Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Along with hydrogen production and use, an energy transition will involve the synchronous upscaling of renewable electricity, batteries, and energy use technologies. For hydrogen, the platinum group metals used in PEM electrolysers and fuel cells are critical. Targets for hydrogen demand beyond 2050 are much greater.
