It was received considerable research as a hydrogen and energy storage media due to its high gravimetric and volumetric hydrogen density (10 wt%, 148 kg H 2 m −3, respectively). AlH 3 has been utilized as a reducing agent for some chemical reactions, as an additive in the solid propellant to improve the specific impulse, and as a hydrogen …
Meanwhile, although the cryogenic storage method provides a high volumetric capacity, it consumes more energy to maintain cryogenic temperatures, which makes it challenging to apply in practice. Chemical storage via catalytic hydrogenation of small unsaturated organic molecules has been considered an alternative option [ 7, 8 ].
Most interestingly, energy loss (U l) is well maintained at about 8%@550 MV m −1, which is rather close to biaxially oriented polypropylene (BOPP).

A complete LOHC system consists of reversible cycle dehydrogenation and hydrogenation for release and storage of hydrogen respectively. Though hydrogenation system efficiency is high i.e., 98–99%, still dehydrogenation system''s efficiency is dependent on various operational parameters.
The ideal scenario for stationary application would require MH to have high volumetric and gravimetric hydrogen densities. As shown in Figure 2, complex hydrides such as Mg(BH 4) 2, Al(BH 4) 2 and LiBH 4 are capable of meeting high density requirements but are limited by their irreversible nature (Lai and Aguey-Zinsou, 2018).The alternative option is in using …
