Hydride storage systems
In metal hydride storage systems the hydrogen forms interstitial compounds
with metals. Here molecular hydrogen is first adsorbed on the metal surface and then incorporated in elemental form (H) into the metallic lattice with heat output
and released again with heat input. Metal hydrides are based on elemental metals such as palladium, magnesium and lantha- num, intermetallic compounds, light metals such as aluminium, or certain alloys. Palla- dium, for example, can absorb a hydrogen gas volume up to 900 times its own volume
I didnt know this! Very interesting
