How do you expect the metallic hydrides to be useful for hydrogen storage? Explain.

(N/A) Metallic hydrides are hydrogen-deficient,meaning they do not follow the law of constant composition. It has been established that in the hydrides of $Ni$,$Pd$,$Ce$,and $Ac$,hydrogen occupies the interstitial positions in the metal lattices. This allows for the further absorption of hydrogen into these metals. Metals like $Pd$ and $Pt$ have the capacity to accommodate a large volume of hydrogen. Therefore,they are used for the storage of hydrogen and serve as a potential source of energy.
