Hydrogen Energy Storage - an overview | ScienceDirect Topics

Paul Breeze, in Power System Energy Storage Technologies, 2018. Abstract. Hydrogen energy storage is another form of chemical energy storage in which electrical power is converted into hydrogen. This energy can then be released again by using the gas as fuel in a combustion engine or a fuel cell. Hydrogen can be produced from electricity by the electrolysis of water, a simple process that can
