Storage of hydrogen on a large scale (of more than one hundred tonnes of hydrogen) is still relatively scarce nowadays . Such existing large scale storages are underground storage e.g. the salt caverns in Texas, USA and Teeside in the UK. However, this kind of storage is not possible everywhere and presents some drawbacks.
Storage of hydrogen in the form of methane (natural gas) may be a preferable alternative for overcoming the storage problems associated with storing pure hydrogen in geological formations. When there is a surplus of renewable energy in the summer, hydrogen can be produced through water electrolysis.
