Report: Hydrogen or batteries for grid storage? A net energy analysis

Energy storage in hydrogen is a technically feasible option for grid-scale storage, and is already in pilot demonstrations. In order to examine the potential benefits and drawbacks of hydrogen as a grid-scale energy storage technology, through a collaborative study, scientists from Imperial College, Stanford University and Western Washington University have looked at the energy efficiency…

Research Development: Efficient water reduction with gallium phosphide nanowires

A solar cell that produces fuel rather than electricity. Researchers at Eindhoven University of Technology (TU/e) and FOM Foundation have presented a very promising prototype of this in the journal Nature Communications. The material gallium phosphide enables their solar cell to produce the clean fuel hydrogen gas from liquid water. Processing the gallium phosphide in the…
