A review. Hydrogen as an energy carrier is very versatile in energy storage applications. Developments in novel, sustainable technologies towards a CO2-free society are needed and the exploration of all-solid-state batteries (ASSBs) as well as solid-state hydrogen storage applications based on metal hydrides can provide solns. for such
The concept of hydrogen storage plays a pivotal role in this scenario, as surplus energy or solar energy can be utilized to produce hydrogen gas which is absorbed by the metal hydrides. When it is needed, the stored hydrogen is released from the metal hydrides, generating heat applicable to various uses.

To explore the hydrogen storage capacity, we further study the structural information of stable structures such as TiH 4 and VH 4. From Fig. 1, the calculated lattice parameters of TiH 4 are a = 2.894 Å and c = 3.809 Å, respectively.
Metal hydrides have higher hydrogen-storage density ( 6.5 H atoms / cm 3 for MgH 2) than hydrogen gas ( 0.99 H atoms / cm 3) or liquid hydrogen ( 4.2 H atoms / cm 3) [3]. Hence, metal hydride storage is a safe, volume-efficient storage method for on-board vehicle applications.
