(Left) The mixed cobalt manganese oxide, Co2MnO4. (Right) a frame from a video showing hydrogen being produced through electrolysis at the current density of 1000 milliamperes per square centimeter.

Much remains to be done to stimulate the production and use of green hydrogen, produced entirely from sun and wind. Electrolysis, the splitting of water into oxygen and hydrogen, with electricity from ...

This clean fuel is produced by splitting water molecules using renewable electricity, a process called electrolysis. Unlike traditional hydrogen, which is often produced using fossil fuels ...
