Hydrogen production. Green algae as a source of energy. (1/164)

Hydrogen gas is thought to be the ideal fuel for a world in which air pollution has been alleviated, global warming has been arrested, and the environment has been protected in an economically sustainable manner. Hydrogen and electricity could team to provide attractive options in transportation and power generation. Interconversion between these two forms of energy suggests on-site utilization of hydrogen to generate electricity, with the electrical power grid serving in energy transportation, distribution utilization, and hydrogen regeneration as needed. A challenging problem in establishing H(2) as a source of energy for the future is the renewable and environmentally friendly generation of large quantities of H(2) gas. Thus, processes that are presently conceptual in nature, or at a developmental stage in the laboratory, need to be encouraged, tested for feasibility, and otherwise applied toward commercialization.  (+info)

The health impacts of exposure to indoor air pollution from solid fuels in developing countries: knowledge, gaps, and data needs. (2/164)

Globally, almost 3 billion people rely on biomass (wood, charcoal, crop residues, and dung) and coal as their primary source of domestic energy. Exposure to indoor air pollution (IAP) from the combustion of solid fuels is an important cause of morbidity and mortality in developing countries. In this paper, we review the current knowledge on the relationship between IAP exposure and disease and on interventions for reducing exposure and disease. We take an environmental health perspective and consider the details of both exposure and health effects that are needed for successful intervention strategies. We also identify knowledge gaps and detailed research questions that are essential in successful design and dissemination of preventive measures and policies. In addition to specific research recommendations, we conclude that given the interaction of housing, household energy, and day-to-day household activities in determining exposure to indoor smoke, research and development of effective interventions can benefit tremendously from integration of methods and analysis tools from a range of disciplines in the physical, social, and health sciences.  (+info)

Daily average exposures to respirable particulate matter from combustion of biomass fuels in rural households of southern India. (3/164)

Indoor air pollution resulting from combustion of biomass fuels in rural households of developing countries is now recognized as a major contributor to the global burden of disease. Accurate estimation of health risks has been hampered by a paucity of quantitative exposure information. In this study we quantified exposures to respirable particulate matter from biomass-fuel combustion in 436 rural homes selected through stratified random sampling from four districts of Tamil Nadu, India. The study households are a subset of a larger sample of 5,028 households from the same districts in which socioeconomic and health information has been collected. Results of measurements for personal exposures to respirable particulate matter during cooking were reported earlier. This has been extended to calculation of 24-hr exposures with the aid of additional measurements during noncooking times and the collection of time-activity records. Concentrations of respirable particulate matter ranged from 500 to 2,000 micro g/m(3) during cooking in biomass-using households, and average 24-hr exposures ranged from 90 +/- 21 micro g/m(3) for those not involved in cooking to 231 +/- 109 micro g/m(3) for those who cooked. The 24-hr exposures were around 82 +/- 39 micro g/m(3) for those in households using clean fuels (with similar exposures across household subgroups). Fuel type, type and location of the kitchen, and the time spent near the kitchen while cooking were the most important determinants of exposure across these households among other parameters examined, including stove type, cooking duration, and smoke from neighborhood cooking. These estimates could be used to build a regional exposure database and facilitate health risk assessments.  (+info)

The origin, fate, and health effects of combustion by-products: a research framework. (4/164)

Incomplete combustion processes can emit organic pollutants, metals, and fine particles. Combustion by-products represent global human and environmental health challenges that are relevant not only in heavily industrialized nations, but also in developing nations where up to 90% of rural households rely on unprocessed biomass fuels for cooking, warmth, and light. These issues were addressed at the Seventh International Congress on Combustion By-Products, which convened 4-6 June 2001 in Research Triangle Park, North Carolina. This congress included a diverse group of multidisciplinary researchers and practitioners who discussed recent developments and future goals in the control of combustion by-products and their effects of exposure on human and ecologic health. Participants recommended that interdisciplinary, coordinated research efforts should be focused to capitalize on the important potential synergisms between efforts to reduce the adverse human health effects linked to exposures to combustion by-products and broader efforts to reduce greenhouse gas emissions and save energy through efficiency. In this article we summarize the principal findings and recommendations for research focus and direction.  (+info)

Electricity generation by direct oxidation of glucose in mediatorless microbial fuel cells. (5/164)

Abundant energy, stored primarily in the form of carbohydrates, can be found in waste biomass from agricultural, municipal and industrial sources as well as in dedicated energy crops, such as corn and other grains. Potential strategies for deriving useful forms of energy from carbohydrates include production of ethanol and conversion to hydrogen, but these approaches face technical and economic hurdles. An alternative strategy is direct conversion of sugars to electrical power. Existing transition metal-catalyzed fuel cells cannot be used to generate electric power from carbohydrates. Alternatively, biofuel cells in which whole cells or isolated redox enzymes catalyze the oxidation of the sugar have been developed, but their applicability has been limited by several factors, including (i) the need to add electron-shuttling compounds that mediate electron transfer from the cell to the anode, (ii) incomplete oxidation of the sugars and (iii) lack of long-term stability of the fuel cells. Here we report on a novel microorganism, Rhodoferax ferrireducens, that can oxidize glucose to CO(2) and quantitatively transfer electrons to graphite electrodes without the need for an electron-shuttling mediator. Growth is supported by energy derived from the electron transfer process itself and results in stable, long-term power production.  (+info)

Exposure assessment for respirable particulates associated with household fuel use in rural districts of Andhra Pradesh, India. (6/164)

Indoor air pollution associated with combustion of solid fuels seems to be a major contributor to the national burden of disease in India, but relatively few quantitative exposure assessment studies are available. This study quantified the daily average concentrations of respirable particulates (50% cut-off at 4 microm) in 412 rural homes selected through stratified random sampling from three districts of Andhra Pradesh, India and recorded time activity data from 1400 individuals to reconstruct 24-h average exposures. The mean 24-h average concentrations ranged from 73 to 732 microg/m(3) in gas- versus solid fuel-using households, respectively. Concentrations were significantly correlated with fuel type, kitchen type, and fuel quantity. The mean 24-h average exposures ranged from 80 to 573 microg/m(3). Among solid fuel users, the mean 24-h average exposures were the highest for women cooks and were significantly different from men and children. Among women, exposures were the highest in the age group of 15-40 years (most likely to be involved in cooking or helping in cooking), while among men, exposures were highest in the age group of 65-80 years (most likely to be indoors). The data are being used to develop a model to predict quantitative categories of population exposure based on survey information on housing and fuel characteristics. This would facilitate the development of a regional exposure database and enable better estimation of health risks.  (+info)

Potential role of a novel psychrotolerant member of the family Geobacteraceae, Geopsychrobacter electrodiphilus gen. nov., sp. nov., in electricity production by a marine sediment fuel cell. (7/164)

Previous studies have shown that members of the family Geobacteraceae that attach to the anodes of sediment fuel cells are directly involved in harvesting electricity by oxidizing organic compounds to carbon dioxide and transferring the electrons to the anode. In order to learn more about this process, microorganisms from the anode surface of a marine sediment fuel cell were enriched and isolated with Fe(III) oxide. Two unique marine isolates were recovered, strains A1(T) and A2. They are gram-negative, nonmotile rods, with abundant c-type cytochromes. Phylogenetic analysis of the 16S rRNA, recA, gyrB, fusA, rpoB, and nifD genes indicated that strains A1(T) and A2 represent a unique phylogenetic cluster within the Geobacteraceae. Both strains were able to grow with an electrode serving as the sole electron acceptor and transferred ca. 90% of the electrons available in their organic electron donors to the electrodes. These organisms are the first psychrotolerant members of the Geobacteraceae reported thus far and can grow at temperatures between 4 and 30 degrees C, with an optimum temperature of 22 degrees C. Strains A1(T) and A2 can utilize a wide range of traditional electron acceptors, including all forms of soluble and insoluble Fe(III) tested, anthraquinone 2,6-disulfonate, and S(0). In addition to acetate, both strains can utilize a number of other organic acids, amino acids, long-chain fatty acids, and aromatic compounds to support growth with Fe(III) nitrilotriacetic acid as an electron acceptor. The metabolism of these organisms differs in that only strain A1(T) can use acetoin, ethanol, and hydrogen as electron donors, whereas only strain A2 can use lactate, propionate, and butyrate. The name Geopsychrobacter electrodiphilus gen. nov., sp. nov., is proposed for strains A1(T) and A2, with strain A1(T) (ATCC BAA-880(T); DSM 16401(T); JCM 12469) as the type strain. Strains A1(T) and A2 (ATCC BAA-770; JCM 12470) represent the first organisms recovered from anodes that can effectively couple the oxidation of organic compounds to an electrode. Thus, they may serve as important model organisms for further elucidation of the mechanisms of microbe-electrode electron transfer in sediment fuel cells.  (+info)

Evidence for involvement of an electron shuttle in electricity generation by Geothrix fermentans. (8/164)

In experiments performed using graphite electrodes poised by a potentiostat (+200 mV versus Ag/AgCl) or in a microbial fuel cell (with oxygen as the electron acceptor), the Fe(III)-reducing organism Geothrix fermentans conserved energy to support growth by coupling the complete oxidation of acetate to reduction of a graphite electrode. Other organic compounds, such as lactate, malate, propionate, and succinate as well as components of peptone and yeast extract, were utilized for electricity production. However, electrical characteristics and the results of shuttling assays indicated that unlike previously described electrode-reducing microorganisms, G. fermentans produced a compound that promoted electrode reduction. This is the first report of complete oxidation of organic compounds linked to electrode reduction by an isolate outside of the Proteobacteria.  (+info)

TY - JOUR. T1 - Analysis of chitin particle size on maximum power generation, power longevity, and Coulombic efficiency in solid-substrate microbial fuel cells. AU - Rezaei, Farzaneh. AU - Richard, Tom L.. AU - Logan, Bruce E.. PY - 2009/7/15. Y1 - 2009/7/15. N2 - Microbial fuel cells (MFCs) produce bioelectricity from a wide variety of organic and inorganic substrates. Chitin can be used as a slowly degrading substrate in MFCs and thus as a long-term fuel to sustain power by these devices in remote locations. However, little is known about the effects of particle size on power density and length of the power cycle (longevity). We therefore examined power generation from chitin particles sieved to produce three average particle sizes (0.28, 0.46 and 0.78 mm). The longevity increased from 9 to 33 days with an increase in the particle diameter from 0.28 to 0.78 mm. Coulombic efficiency also increased with particle size from 18% to 56%. The maximum power density was lower for the largest (0.78 mm) ...
Microbial fuel cells are batteries in which microorganisms catalyze the conversion of organic fuel (such as lactate) into protons and electrons that power a resistor (e. g., a light bulb) before reducing the terminal electron acceptor (e. g., oxygen is reduced to water). Great improvements in power production and efficiency have been made by engineering inorganic components, such as the electrodes themselves, to be more efficiently utilized by fuel cell-inhabiting organisms. However, other avenues for improvement may exist, that is, engineering the fuel cell-inhabiting organisms themselves. We hypothesized that Shewanella oneidensis MR-1, a model organism used for studying microbial fuel cells, could be shown to evolve under physiological conditions which mimic those found in microbial fuel cells. These physiological conditions include the planktonic lifestyle, the biofilm lifestyle, and transient association between the two - that is, those cells that rapidly detach from and reattach to the ...

Figure 5.6 shows that the introduction of renewable technologies under the Energy [R]evolution scenario increase the future costs of electricity generation compared to the Reference scenario until 2020. This difference will be less than 0.8 US$ct/kWh up to 2020, however. Because of high prices for conventional fuels and the lower CO2 intensity of electricity generation, from 2030 on electricity generation costs will become economically favourable under the Energy [R]evolution scenario and by 2050 costs will be 7.5 US$ct/kWh below those in the Reference version. Under the Reference scenario, on the other hand, unchecked growth in demand, an increase in fossil fuel prices and the cost of CO2 emissions result in total electricity supply costs rising from todays US$ 96 billion per year to more than US$ 555 billion in 2050, compared to US$ 327 billion in the Energy [R]evolution scenario. Figure 5.6 shows that the Energy [R]evolution scenario not only complies with the ASEAN regions CO2 reduction ...
The biocathodic reduction of nitrate in Microbial Fuel Cells (MFCs) is an alternative to remove nitrogen in low carbon to nitrogen wastewater and relies entirely on microbial activity. In this paper the community composition of denitrifiers in the cathode of a MFC is analysed in relation to added electron acceptors (nitrate and nitrite) and organic matter in the cathode. Nitrate reducers and nitrite reducers were highly affected by the operational conditions and displayed high diversity. The number of retrieved species-level Operational Taxonomic Units (OTUs) for narG, napA, nirS and nirK genes was 11, 10, 31 and 22, respectively. In contrast, nitrous oxide reducers remained virtually unchanged at all conditions. About 90% of the retrieved nosZ sequences grouped in a single OTU with a high similarity with Oligotropha carboxidovorans nosZ gene. nirS-containing denitrifiers were dominant at all conditions and accounted for a significant amount of the total bacterial density. Current production ...

I developed a Microbial Fuel Cell (MFC) that unprecedentedly works (i.e., produces electricity) under extreme salinity (≈ 100 g/L NaCl). Many industries, such as oil and gas extraction, generate hypersaline wastewaters with high organic strength, accounting for about 5% of worldwide generated effluents, which represent a major challenge for pollution control and resource recovery. This study assesses the potential for microbial fuel cells (MFCs) to treat such wastewaters and generate electricity under extreme saline conditions. Specifically, the focus is on the feasibility to treat hypersaline wastewater generated by the emerging unconventional oil and gas industry (hydraulic fracturing) and so, with mean salinity of 100 g/L NaCl (3-fold higher than sea water). The success of this novel technology strongly depends on finding a competent and resilient microbial community that can degrade the waste under extreme saline conditions and be able to use the anode as their terminal electron acceptor ...

The GeO2 electrode shows a low coulombic efficiency in the first cycle (43%), which is mainly caused by a poor Ge oxidation kinetics (Ge + 2Li2O → GeO2 + 2Li+ + 2e-). The X-ray absorption spectroscopy (XAS) data illustrate that ...
The ability of Pelobacter carbinolicus to oxidize electron donors with electron transfer to the anodes of microbial fuel cells was evaluated because microorganisms closely related to Pelobacter species are generally abundant on the anodes of microbial fuel cells harvesting electricity from aquatic sediments. P. carbinolicus could not produce current in a microbial fuel cell with electron donors which support Fe(III) oxide reduction by this organism. Current was produced using a coculture of P. carbinolicus and Geobacter sulfurreducens with ethanol as the fuel. Ethanol consumption was associated with the transitory accumulation of acetate and hydrogen. G. sulfurreducens alone could not metabolize ethanol, suggesting that P. carbinolicus grew in the fuel cell by converting ethanol to hydrogen and acetate, which G. sulfurreducens oxidized with electron transfer to the anode. Up to 83% of the electrons available in ethanol were recovered as electricity and in the metabolic intermediate acetate. ...
Under anaerobic conditions, certain bacteria can produce electricity. This behavior can be exploited in microbial fuel cells, with a special focus on wastewater treatment schemes. A weak point is the dissatisfactory power density of the microbial cells. An unconventional solution is now presented by Singaporean and Chinese scientists: as reported in the journal Angewandte Chemie, they coated live, electroactive bacteria with a conducting polymer and obtained a high-performance anode for microbial fuel cells.. The history of microbial fuel cells goes back to the beginning of the 20th century when scientists connected bacteria cells with electrodes to generate electricity. The principle is that, if no oxygen is present, the bacterias metabolism changes to produce protons and electrons instead of carbon dioxide and water. These electrons can be used for current generation in an electrochemical cell. Such microbial fuel cells are currently heavily investigated for sustainable energy production and, ...

Microbial Fuel Cells (MFCs) are emerging as an effective means of treating different types of waste including urine and wastewater. However, the fate of pathogens in an MFC-based system remains unknown, and in this study we investigated the effect of introducing the enteric pathogen Salmonella enterica serovar enteritidis in an MFC cascade system. The MFCs continuously fed with urine showed high disinfecting potential. As part of two independent trials, during which the bioluminescent S. enteritidis strain was introduced into the MFC cascade, the number of viable counts and the level of bioluminescence were reduced by up to 4.43±0.04 and 4.21±0.01 log-fold, respectively. The killing efficacy observed for the MFCs operating under closed-circuit conditions, were higher by 1.69 and 1.72 log-fold reduction than for the open circuit MFCs, in both independent trials. The results indicated that the bactericidal properties of a well performing anode were dependent on power performance and the oxidation
The pollution caused by the use of conventional energy sources represents a serious threat to the existing global ecological system, which stimulates the ongoing search for alternative environmentally safe biochemical energy sources that are able to fulfill the future energy demand. The microbial fuel cell (MFC) technology is one of such alternative energy resources conceptualizing the waste-to-energy principle, which can be used for wastewater treatment with simultaneous recovery of bio-energy using microorganisms as biocatalysts. The Membrane bioreactor (MBR) is another promising technology for wastewater treatment, it is combination of activated sludge process and membrane filtration. The integration of these two technologies will be an efficient one for wastewater treatment and bioelectricity generation. The selection of proton conducting and water permeable membrane are currently the key factors that decide the performance of microbial fuel cell (MFC) and Membrane bioreactor (MBR), ...
The slow kinetics of the electrochemical oxygen reduction reaction (ORR) is a crucial bottleneck in the development of microbial fuel cells (MFCs). This article firstly gives an overview of the particular constraints imposed on ORR by MFC operating conditions: neutral pH, slow oxygen mass transfer, sensitivity to reactive oxygen species, fouling and biofouling. A review of the literature is then proposed to assess how microbial catalysis could afford suitable solutions. Actually, microbial catalysis of ORR occurs spontaneously on the surface of metallic materials and is an effective motor of microbial corrosion. In this framework, several mechanisms have been proposed, which are reviewed in the second part of the article. The last part describes the efforts made in the domain of MFCs to determine the microbial ecology of electroactive biofilms and define efficient protocols for the formation of microbial oxygen-reducing cathodes. Although no clear mechanism has been established yet, several ...

A marine microbial fuel cell (MFC) type biosensor was developed for the detection of assimilable organic carbon (AOC) in ocean water for the purpose of online water quality monitoring for seawater desalination plants prone to biofouling of reverse osmosis (RO) membranes. The anodophilic biofilm that developed on the graphite tissue anode could detect acetate as the model AOC to concentrations as low as 5 µM (120 µg/L of AOC), which is sufficiently sensitive as an online biofouling risk sensor. Although the sensor was operated at a higher (+200 ± 10 mV) than the usual (-300 mV) anodic potential, the presence of oxygen completely suppressed the electrical signal. In order to overcome this outcompeting effect of oxygen over the anode as electron acceptor by the bacteria, hexacyanoferrate (HCF(III)) was found to enable the development of an adapted biofilm that transferred electrons to HCF(III) rather than oxygen. As the resultant of the reduced HCF(II) could readily transfer electrons to the ...

An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery can be recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and both batteries can provide electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

Microbial fuel cells (MFCs), which convert organic waste to electricity using microbes, could be used to make the wastewater infrastructure more energy efficient and sustainable. However, the chemical catalysts which catalyse the oxygen reduction reaction (ORR) at the cathode of MFCs are expensive and unsustainable. Mixed community aerobic biocathode biofilms are an alternative to chemical catalysts. However, little is known about the bacteria, their metabolism, and their mechanisms of electron transfer with the electrode. A novel 4-electrode method was used to determine the minimum potential for production of peroxide on a porous carbon felt biocathode support. Biocathodes with a high onset potential for the ORR of +0.4 V vs Ag/AgCl were then cultivated in poised-potential half-cells at working electrode potentials of -0.1 and +0.2 V vs Ag/AgCl. These biofilms show what may be an electrode potential-dependent switch in an electron transfer mechanism from -0.1 to +0.2 V vs Ag/AgCl. The biofilms ...
0019] As shown in the lower portion of FIG. 2, conventional ball milling of K2FeO4 heats the particles and converts some to the ferric state. Chemically synthesized, re-crystallized K2FeO4 was milled in a Restch PM 100 planetary ball in a steel vessel with steel grinding balls at approximately 500 revolutions per minute (rpm) ball milling for approximately 45 minutes. The resulting nanometer-size particles and 10 weight percent carbon (based on the total amount of K2FeO4 and carbon) were used to form a cathode. The cathode had a decreased coulombic efficiency (approximately 37%) compared to the coulombic efficiency of a comparable cathode made using non-milled K2FeO4 (53% coulombic efficiency). However the discharge voltage increased and the coulombic efficiency increased to approximately 47% when the milling time was shortened to approximately 15 minutes. As seen an the upper portion of FIG. 2, at a lower mill speed of approximately 300 rpm for approximately 30 minutes, the coulombic efficiency ...
Physicist: Electrical energy is nothing special. Just like the chemical energy in our bodies, it breaks down into heat. For example, the heat given off by light bulbs (or electric heaters for that matter!) is a result of electrical energy. When electricity is flowing to a light bulb, thats where the electrical energy is going; its turning into light. When you pull the plug (so to speak) what tiny, tiny amount of electrical energy there is in the wires runs out almost immediately.. The term electrical energy is actually a little vague. So, to be specific, in our nervous system there are tiny ion pumps that maintain an imbalance of charges between the inside and outside of the nerve cells. When a nerve cell fires, charges are allowed to suddenly flow through the cell membrane in a process called an action potential. The way electricity flows along nerve cells is different from the way it flows down a telegraph wire (inside-to-outside instead of along), but whatever. The point is, there ...
Bioelectrochemical systems (BES), including their most important variant, the microbial fuel cell (MFC), are rapidly developing and promising technologies for renewable energy production and wastewater treatment, among other applications (1, 2). The MFC technology aims at generating electrical current through extracellular transfer of electrons, which microorganisms liberate from organic substrates. Microorganisms oxidize organic compounds, and the electrons from the intracellular electron transport chains are transferred to an external electron acceptor (i.e., an anode poised at a suitable potential) (3). One of the challenges facing MFC performance is the efficiency of microbial electron transfer to an anode. The most commonly described transfer mechanisms are direct electron transfer via direct cell contact or protein nanowires and mediated electron transfer via secondary or primary metabolites (4-9). Attempts to improve the biological efficiency of MFCs have therefore focused on ...
This paper describes the detrimental effect of photosynthetically evolved oxygen on anodic current generation in the presence of riboflavin upon illumination of a mixed phototrophic culture enriched from a freshwater pond at +0.6 V vs standard hydrogen electrode. In the presence of riboflavin, the phototrophic biomass in the anodic compartment produced an electrical current in response to light/dark cycles (12 h/12 h) over 12 months of operation, generating a maximum current density of 17.5 mA.m(-2) during the dark phase, whereas a much lower current of approximately 2 mA.m(-2) was generated during illumination. We found that the low current generation under light exposure was caused by high rates of reoxidation of reduced riboflavin by oxygen produced during photosynthesis. Quantification of biomass by fluorescence in situ hybridization images suggested that green algae were predominant in both the anode-based biofilm (55.1%) and the anolyte suspension (87.9%) with the remaining biovolume ...
As populations continue to grow, the amount of waste produced also increases; 61 percent of energy is wasted by the U.S. economy each year, and most of it can be attributed to our relatively inefficient power plants.1 Fuel cells are capable of reducing waste to increase efficiency and produce marketable energy. Processed municipal waste produces anaerobic digested gas, commonly known as biogas, which can be used as a fuel for fuel cells cell fuel. While hydrogen is the most common fuel type for fuel cells, biogas such as methane, natural gas, propane and diesel can be used as well. Biogas is an ideal option for fuel cells because it is easily stored and produces almost zero net carbon dioxide emissions. When biogas is fed into fuel cells, heat, electricity, and water are produced,2 providing on-site power for the facility. Some fuel cells are efficient enough to create excess hydrogen that can be sold to fuel cell stations and be utilized by fuel cell electric vehicles (FCEV).. The Orange County ...

One of the biggest barriers to greater adoption of hydrogen fuel cell technology is cost.. Not only is hydrogen more expensive than gasoline, diesel and natural gas, the fuel cells themselves are expensive.. A Vancouver company that has been quietly working on fuel cell efficiency since 2001 claims it has a solution that could bring the cost of hydrogen fuel cells down by 25% and has chosen this weeks Hydrogen and Fuel Cells Conference 2013 to go public.. The biennial conference, organized by the Canadian Hydrogen Fuel Cell Association, will draw more than 600 fuel cell scientists and business leaders from 40 countries to Vancouver.. PowerDisc will be among the Canadian companies demonstrating their technology at the conference.. The companys eFlow technology addresses one of the problems inherent in hydrogen fuel cells: an uneven consumption of oxygen and resulting unequal distribution of current, which requires manufacturers to overbuild fuel stacks to make up for the inefficiency.. Weve ...
At the Beijing Motor Show 2018, a new methanol fuel cell supercar was yesterday, 25 April, presented to the public. The company behind the methanol fuel cell car is the German/Chinese joint venture Gumpert Aiways Automobile GmbH that has made the fuel cell integration in close collaboration with the Danish fuel cell developer and manufacturer SerEnergy A/S. SerEnergy has supplied the fuel cell system and been responsible for designing and carrying out the integration of the system.. For the Danish methanol fuel cell company SerEnergy, the collaboration with Gumpert Aiways started in mid-2017. The two companies quickly found that they shared a vision, and with a joint understanding, it didnt take long before the first steps of the development were carried out. The first car, a proof of concept test car, was designed and built in Ingolstadt, Germany, and the designers and developers at SerEnergys headquarters in Aalborg, Denmark, was deeply involved throughout the process designing the fuel cell ...

Humans are highly electrical creatures. For example, the health of our hearts and brains is measured by their electrical activity using EKGs and EEGs. Every cell in our body carries an electrical charge. Our central nervous system and autonomic nervous system both utilize electrical signaling to transmit critical biological messages. In fact, the sophisticated communications of our nervous system act very much like a human Internet.. So what happens when we are exposed to dirty electricity? Scientists believe this chaotic electrical energy can couple to our bodies and create biological harm. For example, the artificial electromagnetic fields from dirty electricity and other EMF pollution may interfere with the natural electrical communication in our bodies, interrupting essential biological functions and triggering a variety of adverse health symptoms and more serious problems over time.. Research shows that exposure to dirty electricity can lead to inflammation, headaches, lack of focus, ...
The depletion of fossil fuel reserves, global warming, energy security and the need for clean, cheap fuels has made developing sources of renewable energy a global research priority. Microbial Fuel Cells (MFCs) have the potential to generate renewable electricity from a vast array of carbon sources such as waste-water, agricultural by-products and industrial pollutants. In MFCs electrons from microbial metabolism flow from the bacteria toward an anode then on through an external circuit finally converting oxygen into water at the cathode closing the cycle. The optimization of MFC systems is a highly multidisciplinary area of research and two complementary areas of work are required - firstly to design more efficient hardware for the cells by traditional engineering and secondly to understand and improve the interaction and electron transport between microbes and electrode via biological engineering. One of the most important engineering challenges in MFC development is the efficient electron ...
The Tricolor project wants to increase the use of biomass for sustainable heat or electricity production. At the core of the project are transnational networks through which experience and knowledge will be shared.. Today, the potential of the available bioenergy is not fully used, and the project argues that an increase would favor the climate and create job opportunities. Renewable energy is high on the European agenda and efficient use of woody biomass is a common strategic field of interest in the Baltic Sea region. During the last decades, the traditional use of wood for heating has developed in Sweden, Estonia and Ukraine. Despite this progress, some common challenges remain. They include energy wood supply, information support and business models in biomass and cooperation. To meet these challenges, channels for knowledge sharing and cooperation within the area must be developed.. The project aims to strengthen and expand an existing transnational network. The network will focus on ...
A secondary electrochemical cell with at least one positive electrode includes an active material and one negative electrode, which are held directly in a hermetically tight housing which has at least one detector element or which is dynamically connected to one such detector element. The detector element is designed or can be set to acquire a predetermined unallowable operating state of the secondary electrochemical cell, and in an unallowable operating state of the secondary electrochemical cell, to actuate at least one switching element which prevents recharging and/or discharging of the secondary electrochemical cell. By making the housing as a hermetically tight protective housing, which is part of an implantable medical device, contamination of surrounding tissue with toxic substances and hazard to the implant wearer by the malfunction of the secondary electrochemical cell can be precluded under all operating conditions with simultaneously great reduction of all dimensions.

Electrical energy comes from renewable and nonrenewable sources; it is generally inexpensive and readily available, but it leaves many appliances and heating units defunct when power supplies are...
A fuel cell is an electrochemical cell that converts the chemical energy from a fuel into electricity through an electrochemical reaction of hydrogen fuel with oxygen or another oxidizing agent.[9] Fuel cells are different from batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy comes from chemicals already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied.. The first fuel cells were invented in 1838. The first commercial use of fuel cells came more than a century later in NASA space programmes to generate power for satellites and space capsules. Since then, fuel cells have been used in many other applications. Fuel cells are used for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas. They are also used to power fuel cell vehicles, including forklifts, automobiles, ...
In experiments, biofuel cells have harnessed membranes of living bacteria to separate anode from cathode--enabling them to share an electrolyte chamber like a lead-acid battery. Now, researchers at the Pacific Northwest National Laboratory have purified the essential protein performing a fuel-cell membranes electronic function, clearing the way to commercialize biofuel cells sans bacteria. The team purified the bacterium down to the essential protein in the cell wall--eliminating the need to keep the bacterium alive. The only missing element was a fuel source, which biomass could supply, lab scientists reasoned. Now they propose biofuel cell arrays to harvest biomass in tiny reactors. The reaction creates a mobile electron carrier that shuttles electrons to the protein-coated electrodes, generating electricity as it neutralizes the biomass. The proposed biofuel cells would use a cheap porous hematite electrode in which the bacterias purified protein could be bound. The coated electrodes would ...
Something big may be brewing on the sewage treatment circuit thanks to a new design that puts bacteria on double-duty-treating wastewater and generating electricity at the same time. The key is an innovative, single-chambered microbial fuel cell. A fuel cell operates akin to a battery, generating electricity from a chemical reaction. But instead of running down unless its recharged, the cell receives a constant supply of fuel from which electrons can be released. Typical fuel cells run off of hydrogen. In a microbial fuel cell, bacteria metabolize their food-in this case, organic matter in wastewater-to release electrons that yield a steady electrical current.
One of the remaining challenges driving polymer electrolyte membrane hydrogen fuel cell research is the durability of the Pt oxygen reduction reaction (ORR) catalyst. Pt is inherently unstable; minute amounts (in the order of ng/cm2 are dissolved every time the fuel cell is started, goes from idle to load, or shut-down. In addition, corrosion of carbon-based materials (ubiquitous inside fuel cells) occurs during the start-up and shut-down and also contributes to the steady decline of fuel cell performance. Adding oxygen evolution reaction (OER) catalysts, of which only Ru and Ir are stable in the acidic conditions of the fuel cell, can decrease Pt loss and carbon corrosion by mitigating the degradation mechanism which occurs during the start-up and shut-down phases. There are two challenges in developing this materials solution (there are other solutions, based on hardware systems) to the fuel cell durability problem: 1) finding the right mixture of Ru and Ir, (Ru is cheaper, more active, but ...
Methods and systems for fuel, chemical, and/or electricity production from electrochemical cells are disclosed. A voltage is applied between an anode and a cathode of an electrochemical cell. The anode includes a metal or metal oxide electrocatalyst. Oxygen is supplied to the cathode, producing oxygen ions. The anode electrocatalyst is at least partially oxidized by the oxygen ions transported through an electrolyte from the cathode to the anode. A feed gas stream is supplied to the anode electrocatalyst, which is converted to a liquid fuel. The anode electrocatalyst is re-oxidized to higher valency oxides, or a mixture of oxide phases, by supplying the oxygen ions to the anode. The re-oxidation by the ions is controlled or regulated by the amount of voltage applied.
Ancient cultures understood that the body possessed a special energy that was responsible for life. The Chinese called this life force energy, Qi. I believe that what they were talking about is bioelectricity.. Bioelectricity. Electricity is a force that results from the interaction between positive and negative charges. Like charges repel while opposites attract. In the body there are different atoms and molecules that have positive or negative charges associated with them. We call these charged particles ions. Bioelectricity (the kind of electricity used in the body) is generated by the movement of these ions.. It is the controlled flow of ions that allows signals to be carried by the nerves of our brains and nervous systems. That means that every thought we have is a result of bioelectricity. This same basic process is responsible for the contraction of our muscles. So, every movement we make and every beat of our hearts are powered by electricity. But there are still deeper implications of ...

TY - JOUR. T1 - Current as an indicator of ammonia concentration during wastewater treatment in an integrated microbial electrolysis cell - Nitrification system. AU - Zhao, Nannan. AU - Angelidaki, Irini. AU - Zhang, Yifeng. PY - 2018. Y1 - 2018. N2 - A key challenge for ammonia monitoring during nitrogen removal process is the extra cost and toxic reagent consuming. Herein the feasibility of current generated by an integrated microbial electrolysis cell (MEC) - nitrification reactor as an indicator of initial ammonia levels (NH3/NH4+) in wastewater was explored. In this loop system, ammonia was first oxidized to nitrate in the nitrification reactor, and then the effluent was introduced into the cathode of MEC where nitrate was reduced as electron acceptor. The correlation between current and ammonia concentration was first investigated with synthetic ammonia-rich wastewater. A good linear relationship (R2 = 0.9419) was observed between current (0.5130-3.906 mA) and ammonia levels (0-62.1 mg ...
Up until now, the issue of using hydrogen fuel cells as alternative sources of power has been a matter of debate. They required fossil fuels for production, needed external inputs of electricity to operate, and were too expensive to be considered as an all-encompassing solution to the global climate crisis. Enter the mighty microbe and a team of brilliant US researchers to provide a little hope for hydrogen.. An article recently published in the National Academy of Sciences describes the newly developed MEC, or Microbial Electrolysis Cell which generates its own hydrogen without the aid of external electricity. Through a process called Reverse Electrodialysis, the cell uses fresh and saltwater membranes to generate and collect power from charged particles created between the gradients. In addition, the microbes manufacture hydrogen gas and small amounts of electricity by breaking down organic material.. This technology has implications far beyond transportation. Without drawing power from the ...

Electricity production is measured at the terminals of all alternator sets in a station. In addition to hydropower, coal, oil, gas, and nuclear power generation, it covers generation by geothermal, solar, wind, and tide and wave energy, as well as that from combustible renewables and waste. Production includes the output of electricity plants that are designed to produce electricity only as well as that of combined heat and power plants.This page has the latest values, historical data, forecasts, charts, statistics, an economic calendar and news for Electricity production (kWh) in Nicaragua.
In this investigation the electricity generation and the electricity capacity of energy mix for sub Saharan Africa from 2020 to 2040 including CO2 emission from (coal, oil, gas) (Total Final Consumption, transport) and power generation were analyzed. These energy sources include conventional and renewable energy sources such as coal, oil, gas, hydro, nuclear, bioenergy, solar PV, and other renewables. We developed a linear regression equation based on the least-square method of estimation to forecast the value of energy and CO2 emission. We fit a linear trend to the energy time series including CO2 emission to show how simple linear regression analysis can be used to forecast future value. The predicted results from 2020 to 2040 show that the electricity capacity and the electricity generation from gas, hydro, solar PV and other renewables will dominate compared to nuclear and bioenergy. Some forms of energies contributions such as nuclear and bioenergy will remain insignificant. The gas will
We report a MEMS (Micro-Electro-Mechanical Systems)-based microbial fuel cell (MFC) that produces a high power density. The MFC features 4.5-μL anode/cathode chambers defined by 20-μm-thick photo-definable polydimethylsiloxane (PDMS) films. The MFC uses a Geobacter-enriched mixed bacterial culture, anode-res
Microbial electron transfer has recently gained considerable attention, as it is fundamental in the development of bioelectrochemical applications for renewable bioenergy and bioremediation of waste. Until now, most attention has been focused on the metal reducing bacteria Shewanella oneidensis and Geobacter sulfurreducens, which are capable of extracellular electron transfer over micrometer distances. Yet large-scale applications of these bioelectrochemical systems are still limited. Due to their capability for long-distance electron transport (LDET; centimeter scale), cable bacteria have emerged as a new and unique opportunity for electromicrobiological research. Recently, cable bacterium filaments have been found attached to the anode of a benthic microbial fuel cell, suggesting they can interact with electrodes and hence may play a potential role in bioelectrochemical systems. Unraveling the electron transfer mechanism of cable bacteria is therefore necessary to see if and how they can be ...
The hydrogen fuel cell is a clean and efficient way to store energy and produce electricity.. With this system, students have a real example of new energy technology.. Using a bulb or solar energy, the solar panel in this system converts the light energy into electricity.. This energy is then used for electrolysis, which produces oxygen and hydrogen from water. The hydrogen is stored in a tank to be used later with the fuel cell.. The hydrogen is used as a fuel by the fuel cell, the oxygen being the combustive. The process that takes place in the fuel cell can be considered the reverse reaction to the electrolysis of water: water, electricity and heat is then produced from hydrogen and oxygen.. In the case of this system, the electricity produced by the fuel cell is used to operate a ventilator. This fuel cell has a performance level of about 50%.. The electrolyzer, like the fuel cell, is based on a proton exchange membrane (PEM). This membrane is composed of a solid polymer electrolyte ...

Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient refueling and less of a carbon footprint.. Researchers at the University of Delaware are working on technology to make fuel cells cheaper and more powerful so that fuel cell vehicles can be a viable option for all someday. Traditional fuel cell research involves hydrogen fuel cells, but the UD researchers are engineering fuel cells that utilize ammonia instead.. In a new analysis published in the journal Joule, a team of engineers at the Center for Catalytic Science and Technology found that among fuels produced from renewable energy, ammonia has the lowest cost per equivalent gallon of gasoline.. As a nitrogen-based liquid fuel, ammonia is cheaper to store and distribute than hydrogen and avoids the carbon dioxide emissions of other liquid fuels, which are expensive to ...
Early work with biofuel cells, which began in the early 20th century, was purely of the microbial variety.[1] Research on using enzymes directly for oxidation in biofuel cells began in the early 1960s, with the first enzymatic biofuel cell being produced in 1964.[1][4] This research began as a product of NASAs interest in finding ways to recycle human waste into usable energy on board spacecraft, as well as a component of the quest for an artificial heart, specifically as a power source that could be put directly into the human body.[5] These two applications - use of animal or vegetable products as fuel and development of a power source that can be directly implanted into the human body without external refueling - remain the primary goals for developing these biofuel cells.[6] Initial results, however, were disappointing. While the early cells did successfully produce electricity, there was difficulty in transporting the electrons liberated from the glucose fuel to the fuel cells electrode ...
14 Single- and multi-​walled carbon nanotubes from different sources were characterized in detail, and the characteristics obtained were carefully analyzed. The carbon material with the highest capacitance, and also other superior properties (Taunit-​M from NanoTechCenter, Russia)​, was chosen for further modification and fabrication of buckypaper based electrodes. These electrodes were biomodified with plant and fungal laccases, as well as fungal bilirubin oxidase. The designed biocathodes were studied in simple buffers and also in a complex physiol. fluid (human serum)​. Biocathodes based on immobilized fungal laccase were bioelectrocatalytically inactive in chloride contg. media at neutral pH. In spite of the quite high current densities realized using biodevices based on plant laccase and fungal bilirubin oxidase, the limited thermal stability of the enzymes renders the biocathodes inadequate for practical applications in implanted situations ...
Electricity, defined by Merriam-Webster, is as follows: a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expensed in terms of the movement and interaction of electrons.. Generally speaking, when thinking of electricity, we think of it as something external to our human bodies: the naturally occurring lightning and human created technology being two said instances. There is, however, a form of electricity that is prevalent in every living creature: bioelectricity.. Bioelectricity is the electric phenomena related to living organisms. It is bioelectricity that enables a shark to map the ocean floor. It is bio-electromagnetic phenomena that enable migratory birds to travel great distances at the same time each year with the accuracy we have only been able to reproduce with maps and GPS. It is bioelectricity that enables the electric eel to generate large fields of current outside their ...

Morupule B Power Station, a coal-fired power station built by the China National Electric Engineering Corporation, has been credited to spurring electricity production in Botswana, Statistics Botswana said Wednesday.
In the operation of many common devices and processes, more than 60% of consumed energy is wasted in many common processes. These loses come in many forms including heat, friction, and vibration. Energy harvesters are devices that can recapture some of this waste energy and convert it into electrical energy. This work will focus on electrostatic energy harvesting devices that recapture vibrational energy. Electrostatic energy harvesters recapture mechanical energy when a conductive mass translates or deforms in an electric field. Polymer ionic liquid gel beads may serve as a useful replacement for fluid droplets in electrostatic energy harvesters.. This work uses a recently developed method for reliable synthesis of polymer gel beads. These beads are synthesized using a micro-reactor, which generates monomeric droplets in a silicon oil carrier fluid. The monomer solution also contains a photoinitiator and cross linker, which enables the monomer to polymerize when exposed to UV light. The present ...

Image:Bacon.jpg,thumb]] With the present interest in fuel cells - devices for directly generating electricity by chemically combining a fuel and oxygen - it is possible to forget that this technology goes back a long way. The first known example was the gas battery, invented by William Robert Grove in the mid-19th century. But perhaps the most interesting figure to pioneer fuel cell technology in the early to mid-twentieth century was Francis Thomas Bacon. Francis Thomas Bacon was a forerunner in fuel cell technology. A descendant of the famous early modern English philosopher and champion of science Francis Bacon, F.T. Bacon was born in Billericay, UK, on 21 December 1904. Trained as an engineer at Trinity College, Cambridge, and employed by steam turbine builder C.A. Parsons in the 1930s, Bacon was fascinated by the ability of fuel cells to directly convert chemical into electrical energy. Although they were then considered a mere scientific curiosity, he became convinced of their ...
Researchers at Penn State University, led by Dr. Bruce Logan, have found that methane can be directly produced using a biocathode containing methanogens in electrochemical systems (abiotic anode) or microbial electrolysis cells (MECs; biotic anode) by a process called electromethanogenesis.

Microbially catalyzed oxidation-reduction reactions drive nutrient cycling and energy flux on Earth. Photoautotrophs, which include the cyanobacteria (oxygenic) and purple and green sulfur bacteria (anoxygenic), transform light energy into chemical energy and are responsible for substantial global primary productivity. Anoxygenic phototrophs, in particular, play a crucial role in biogeochemical cycling in anoxic illuminated environments because of their ability to oxidize an array of inorganic compounds for CO2 fixation. Electron donors include molecular hydrogen, nitrite, and reduced sulfur compounds. Recent evidence has also suggested that solid-phase conductive substances (SPCSs), including rust (mixed-valent iron minerals) and their proxies (poised electrodes), can serve as electron donors for anoxygenic phototrophs. This phenomenon is called phototrophic extracellular electron uptake (EEU) and is the reverse process of extracellular electron transfer (EET) performed by metal-reducing bacteria.
Besides moving forward in transportation, fuel cells are also making headway powering buildings, especially if The Cube makes it successfully to market.. Maryland-based Redox Power Systems, which is developing The Cube, thinks it has the answer. The company, which started up last year, is commercializing University of Maryland technology that could potentially be game-changing for distributed energy.. The Cube fuel cell is slightly bigger than a dishwasher (10% of the size of fuel cells today) and costs 90% less than fuel cells currently on the market. It connects to a natural gas line and electrochemically converts methane to electricity, says Forbes. and produces both heat and electricity. It has no engine and virtually no moving parts and operates silently and constantly.. Eric Wachsman, director of University of Marylands Energy Research Center, developed the solid oxide fuel cell technology, which can provide safe, efficient, reliable, uninterrupted power, on-site … and, the holy grail ...
In a study published March 9 in Nature Chemistry, University of Wisconsin-Madison chemistry Professor Kyoung-Shin Choi presents a new approach to combine solar energy conversion and biomass conversion, two important research areas for renewable energy.. For decades, scientists have been working to harness the energy from sunlight to drive chemical reactions to form fuels such as hydrogen, which provide a way to store solar energy for future use. Toward this end, many researchers have been working to develop functional, efficient and economical methods to split water into hydrogen, a clean fuel, and oxygen using photoelectrochemical solar cells (PECs). Although splitting water using an electrochemical cell requires an electrical energy input, a PEC can harness solar energy to drive the water-splitting reaction. A PEC requires a significantly reduced electrical energy input or no electrical energy at all.. In a typical hydrogen-producing PEC, water reduction at the cathode (producing hydrogen) is ...
We present the fabrication of an ultra-low cost, disposable, solvent-free air cathode all-paper microbial fuel cell (MFC) that does not utilize any chemical treatments. The anode and cathode were fabricated by depositing graphite particles by drawing them on paper with a pencil (four strokes). Hydrophobic parchment paper was used as a proton exchange membrane (PEM) to allow only H+ to pass. Air cathode MFC technology, where O2 was used as an electron acceptor, was implemented on the paper platform. The bioelectric current was generated by an electrochemical process involving the redox couple of microbial-activated extracellular electron transferred electrons, PEM-passed H+, and O2 in the cathode. A fully micro-integrated pencil-traced MFC showed a fast start-time, producing current within 10 s after injection of bacterial cells. A single miniaturized all-paper air cathode MFC generated a maximum potential of 300 mV and a maximum current of 11 μA during 100 min after a single injection of Shewanella
Each power source should be marked on its rating plate, Fig.1, with an IP rating which provides information about the degree to which the equipment is protected against water. Normally equipment will be IP21 or IP23. The second number describes protection against water ingress. A power source marked IP21 is protected from vertical drops of water, as for example may occur if the roof leaks. If the equipment is marked IP23, this means that the equipment is protected at up to 60° from the vertical and is thus suitable for outdoor use.. Areas of increased risk are in wet or humid conditions, confined spaces or when the welder is exposed to large areas of bare metal. For use in this type of environment, it is important to use a power source with an S mark, which means that the no-load voltage is below 48V rms AC or 113V peak DC.

Li metal is known to suffer from poor coulombic efficiency and severe dendrite growth in conventional electrolytes (30), but because it has the highest gravimetric capacity of all possible anodes (3863 mAh·g−1), there are still numerous efforts to try to enable this anode in a rechargeable battery. Using solvents of low viscosity (31), increased pressure on the electrode (32), and a surface coverage of LiF (33) are all promising methods to improve the Li metal anode cyclability and lower the severity of dendrite formation. The exceptionally low viscosity, high vapor pressure, and LiF chemical reduction products are all properties inherent to the fluoromethane liquefied gas solvent. To explore the effectiveness of the proposed electrolyte system in enabling the Li metal anode, we measured the coulombic efficiency of Li plating and stripping on polished stainless steel electrodes. As shown in Fig. 4B, the fluoromethane-based electrolyte shows a stable and high coulombic efficiency of ~97% over ...
A DC power system receives AC electrical power and DC electrical power from separate first and second sources simultaneously. The DC power system delivers DC electrical power to an output for use by a load requiring DC power. The DC power system includes a converter to convert AC electrical power to DC electrical power and a power sharing control device to control and distribute the DC electrical power to an output. The first source of DC electrical power includes a storage battery, which provides standby DC electrical power to the DC power system. It also includes a power sharing device, which maintains the storage battery fully charged for use at peak loads, when the DC output electrical power is insufficient to meet the DC load. The second source of DC electrical power is a cogenerator such as a fuel cell, a thermo photovoltaic generator or an internal combustion engine and an alternator for generating and delivering DC electrical power to the power sharing device, while producing and delivering
In this paper, an integration design of membrane electrode assemblies in low temperature solid oxide fuel cells (LTSOFCs) is accomplished by using a mixed ionic-electronic conductor. The mixed ionic-electronic conductor is a composite material, LiNiCuZn oxides, Gd2O3 and Sm-doped CeO2 composited with Na2CO3 (LiNiCuZn oxides-NGSDC), which consists of ionic conductor, n-type and p-type semiconductors. The multi-phase composite material can also be used in single layer fuel cell (SLFC) to replace single-phase materials. A SLFC using the LiNiCuZn oxides-NSGDC composite exhibits an OCV of 1.05 V and maximum power density of 800 mW cm-2, which is comparable to the cell performance of conventional LTSOFCs and much higher than that of SLFC reported before. The reasons leading to the good performance are porous structure of electrode and the matching of ionic conductor and semiconductor.. ...
As of late, consumers and companies place emphasized importance on products and services sustainability, but one point worth contemplating is how to manifest sustainability in concrete, realistic terms. All products, bar inherently disposable ones, require inspection, maintenance, and repair. This of course means that cars, elevators, traffic signals, and all variety of devices intertwined in peoples everyday lives receive regular checks. The same concept applies to electricity, a fundamental element of daily life; electric generators, which create electricity, similarly require periodic maintenance. But generators are not only incredibly sophisticated, they can be huge vast and loaded with state-of-the-art-technology - and with all factors considered, conducting an inspection of the device can consume exorbitant amounts of time.. One example can be seen in the realm of thermal power, which accounts for over 60% of all electricity generated in Japan. Thermal power makes use of a massive ...
March 8, 2006. In research aimed at reducing American dependence on petroleum-based fuels, a group of Agricultural Research Service (ARS) scientists has found a way to replace the petroleum used in todays hydrogen fuel cell membranes with naturally occurring products. Justin Barone and colleagues in ARS Environmental Management and Byproduct Utilization Laboratory in Beltsville, Md., have conducted preliminary studies which suggest the possibility of replacing the conventional petroleum-based main membrane in hydrogen fuel cells with biological products.. Hydrogen fuel cells have received a lot of attention as a possible energy conversion mechanism. The coming of whats being called a renewable hydrogen economy is being touted as a feasible alternative to current economic reliance on nonrenewable fossil fuels.. In the hydrogen economy, hydrogen fuel cells would replace internal combustion engines in vehicles, and hydrogen would replace gasoline. However, current hydrogen fuel cell technology ...
There were several new developments today about how Apple will help fuel its new North Carolina data center that powers iCloud. According to a filing today, and as first reported by CNET, Apple tapped Bloom Energy to provide fuel cells to power the data center. Each fuel cell can set off up to 200 kW of power by combining biogas with oxygen and other chemicals. Apple plans to build a 4.8 MW fuel cell farm for its data center that is set to consume a whopping 20 MW of power. Apple will get the other needed energy from an adjacent 174-acre solar farm that is said to bring 20 MW of power toward the plant, according to Apples latest numbers.. Bloom Energy announced today the opening of a new factory in Newark, Del., which will most likely manufacture some- if not most- of the fuel cells that would be used at Apples North Carolina data center. The new factory is set to create hundreds of jobs and open up Bloom Energys business out of California.. Since the Bloom Energy fuel cells require either ...
Two major types of fuel cells vie for vehicle designers attention: PEM, or proton exchange membrane types, and solid oxide fuels cells (SOFCs). PEMs (also known as polymer electrolyte membrane fuel cells) require an expensive catalyst such as platinum, and hydrogen as fuel. Hydrogen itself is costly to produce and runs up the operating cost for such a fuel cell. Nissan Motor Co., Ltd. timed things to coincide with the 2016 Olympics opening in Rio de Janeiro, Brazil for the introduction of their solid oxide fuel cell vehicle, a van that runs on bio-ethanol electric power. Nissans Carlos Ghosn claims this to be a first, with benefits for potential users. The e-Bio Fuel-Cell offers eco-friendly transportation and creates opportunities for … ...
The anaerobic respiratory capabilities of the WT and the recombinant S. oneidensis were also determined under anaerobic conditions with xylose as the sole electron donor and fumarate as the electron acceptor. Similar to the aerobic conditions, the four genetically engineered strains grew faster than that of the WT strain. The recombinant strains XS and GS (harbouring the oxidoreductase pathway) consumed xylose at a rate of ~14.8, and ~17.2 μM/h, respectively, which had a faster xylose consumption rate than that of the strains XE and GE (harbouring the isomerase pathway, ~6.3 and ~9.7 μM/h, respectively) (Fig. 2c, d). Furthermore, the engineered strain GS could intake xylose faster than XS, which indicated that the glucose/xylose facilitator Gxf1 enabled a higher xylose transportation than that of the D-xylose-proton symporter XylT. It was revealed that sugar uptake via facilitated diffusion by Gxf1 required less energy (ATP) than proton symport XylT, and thus the facilitator protein would ...
Today ClimateXChange publishes some analysis Ive done with Keith Bell on security of electricity supply and how we can meet peak electricity demand in Scotland today and throughout the 2020s. Over the coming years we can expect significant changes to the Scottish electricity generation mix with growing renewable penetration and closure of Scotlands existing large power stations. The report shows that, without new schedulable generation capacity in Scotland following the closures of Hunterston and Torness, we will need new capability to import electricity into Scotland at certain times. Ensuring that our future electricity system can meet future demand means we need to think soon about how the electricity system should develop.. The ClimateXChange blog post.

Owing to the serious crossover of methanol from the anode to the cathode through the polymer electrolyte membrane, direct methanol fuel cells (DMFCs) usually use dilute methanol solutions as fuel. However, the use of high-concentration methanol is highly demanded to improve the energy density of a DMFC system. Instead of the conventional strategies (for example, improving the fuel-feed system, membrane development, modification of electrode, and water management), we demonstrate the use of selective electrocatalysts to run a DMFC at high concentrations of methanol. In particular, at an operating temperature of 80°C, the as-fabricated DMFC with core-shell-shell [email protected]@Pt nanocomposites at the anode and core-shell [email protected] nanoparticles at the cathode produces a maximum power density of 89.7 mW cm−2 at a methanol feed concentration of 10 M and maintains good performance at a methanol concentration of up to 15 M. The high selectivity of the electrocatalysts achieved through structural construction ...
Electrolysis behaviors have been investigated based on ceria-based composite electrolytes and fuel cells. The results showed that both proton and oxygen ion conduction exist in the ceria-based composite electrolytes resulting in high current outputs in both fuel cell and electrolysis operations. Corresponding to high current output in the electrolysis cell, a high hydrogen production can be expected. This work has first demonstrated the ceria-based composite electrolyte used for electrolysis process.. ...
Although Iran does have electricity sector problems, these troubles stem from bad policies, not choice of primary energy source. Because most of Irans electricity is generated by natural gas-fired power plants, massive natural gas subsidies have led to unabated consumption and the inability to cover neither maintenance nor new plant construction costs ...
An ambient energy harvesting system, and method of use thereof, includes a magnetic flux-generating assembly (28), a coil (30) positioned adjacent to the magnetic flux-generating assembly (28), and a cantilevered arm (24). Vibration of the cantilevered arm (24) enables relative movement between the magnetic flux-generating assembly (28) and the coil (30) to generate an electric current in the coil (30). An effective flexible length (L) of the cantilevered arm (24) is selected such that applied kinetic energy causes the cantilevered arm (24) to vibrate at approximately its resonant frequency.

Due to low working temperature, high energy density and low pollution, proton exchange fuel cells have been investigated under different operating conditions in different applications. Using platinum catalysts in methanol fuel cells leads to increasing the cost of this kind of fuel cell which is considered as a barrier to the commercialism of this technology. For this reason, a lot of efforts have been made to reduce the loading of the catalyst required on different supports. In this study, carbon black (CB) and carbon nanotubes (CNT) have been used as catalyst supports of the fuel cell as well as using the double-metal combination of platinum-ruthenium (PtRu) as anode electrode catalyst and platinum (Pt) as cathode electrode catalyst. The performance of these two types of electro-catalyst in the oxidation reaction of methanol has been compared based on electrochemical tests. Results showed that the carbon nanotubes increase the performance of the micro-fuel cell by 37% at maximum power density,

A research team led by Professor Keon Jae Lee and Professor Yoon Sung Nam from the Department of Materials Science and Engineering at KAIST has developed the biotemplated design of flexible piezoelectric energy harvesting device, called nanogenerator.. Nature has its own capabilities to spontaneously synthesize and self-assemble universal materials with sophisticated architectures such as shells, sea sponges, and bone minerals. For instance, the natural sea shell, consisting of calcium carbonate (CaCO3), is very rigid and tough whereas the artificial chalk made by the same material is fragile. In addition, most of artificial syntheses are performed under toxic, expensive and extreme environments in contrast to the natural syntheses, which are processed in benign and mild surroundings. If human can mimic these biological abilities, a variety of ecological and material issues can be solved.. The KAIST team modified a M13 viral gene, which is harmless to human and widely exist in nature, to ...
