Electrolysis of water
Electrolysis of water is using electricity to split water into oxygen ( O. 2) and hydrogen ( H. 2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurised into convenient ''tanks'' or ''gas bottles'', hydrogen can ...
