Different modes of pump operation (ﬁxed or variable speed) are considered, the preliminary sizing of the PV ﬁeld and seawater reservoir is performed, and the results are comparatively assessed over a year-long simulated operation. (unifi.it)

Researchers from the Department of Physics at IIT-Madras have developed critical components for a highly efficient, cost-effective way to electrolyze seawater to generate hydrogen. (aspirantiasacademy.in)

A critical step toward decarbonization of the energy sector is the ability to store energy from intermittent renewable energy sources such as the sun, or wind. (yissum.co.il)
There are several possible applications for SWBs to be used as electrochemical devices for load leveling and peak shaving applications to ensure effective integration between renewable energy sources and the electrical grid. (yissum.co.il)

Turning a nuclear facility into an environmentally friendly energy facility that could store excess renewable energy during the day and power up Southern California at dusk is an exciting prospect-potentially eliminating "Duck Curve" issues for much of the region. (powermag.com)

The competition was launched in 2019 with a prize of 3.3 million US dollars and requires a five-stage competition to develop the best wave energy equipment. (lariva2018.com)
