The hitch is that, while an excellent medium for renewable energy storage, hydrogen itself is hard to store. This is because it has a low volumetric energy density compared to other gases — such as natural gas — meaning it takes up significantly more space. Also, hydrogen has a boiling point close to absolute zero and requires cryogenic storage.
Hydrogen offers a potential energy storage medium because of its versatility. The gas can be produced by electrolysis of water, making it easy to integrate with electricity generation. Once made, the hydrogen can be burned in thermal power plants to generate electricity again or it can be used as the energy source for fuel cells.
