  • prices
  • Geographic PPIs for natural gas distribution are useful because prices in this industry tend to change based on local market conditions that result from differences in demand, infrastructure, and weather. (bls.gov)
  • 2016
  • With the release of Producer Price Index (PPI) data for October 2016 on November 16, 2016, the Bureau of Labor Statistics (BLS) introduced indexes for natural gas distribution by region into the official PPI aggregation structures. (bls.gov)
  • primarily
  • Primarily, gas is stored by the process of physical adsorption. (spe.org)
  • The weights for the natural gas distribution indexes are derived primarily from value-of-shipments data, currently from the 2007 U.S. Census Bureau Economic Census . (bls.gov)
  • energy
  • It is an unconventional energy resource, which has become an increasingly important source of natural gas globally and has the potential to grow as a major energy source in the next decade. (spe.org)
  • Shale gas is an important unconventional energy source for our future needs. (spe.org)
  • The stakeholder input process for guiding research and development needs via the Natural Gas Vehicle Technology Forum (NGVTF) to the U.S. Department of Energy and the California Energy Commission is reviewed. (osti.gov)
  • unconventional
  • Previously, adsorption was considered an unconventional mode of gas storage and the effects of gas desorption were usually ignored in conventional reservoir engineering. (spe.org)
  • emissions
  • Current high-level natural gas engine development gap areas are highlighted, including efficiency, emissions, and the certification process. (osti.gov)
  • vehicle
  • A review of current natural gas vehicle offerings is presented for both light-duty and medium- and heavy-duty applications. (osti.gov)
