NREL sets new world efficiency record for solar hydrogen production: 16.2%

Green Car Congress

Scientists at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) recaptured the record for highest efficiency in solar hydrogen production via a photoelectrochemical (PEC) water-splitting process. Structure of an IMM photocathode configured for water splitting with TEM cross-section of the active layers.

New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

As reported in an open-access paper in Nature Communications, the wafer-level photochemical diode arrays exhibited solar-to-hydrogen efficiency of ~3.3% Previous direct solar water splitters have achieved a little more than 1 percent stable solar-to-hydrogen efficiency in fresh or saltwater. in neutral (pH?~?7.0)

NREL shows graded catalytic-protective layer boosts longevity of high-efficiency photocathodes for renewable hydrogen

Green Car Congress

Their works demonstrates the potential of utilizing a hybridized, heterogeneous surface layer as a cost-effective catalytic and protective interface for solar hydrogen production. Using a photoelectrochemical (PEC) device is a promising way to produce hydrogen. Nature Energy 2, Article number: 16192 doi: 10.1038/nenergy.2016.192.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. They are highly automated production islands that directly convert wind energy to hydrogen, with a few of them processing the gas into fuels and other goods.
