Magnesium-based hydrogen storage alloys have attracted significant attention as promising materials for solid-state hydrogen storage applications due to their high hydrogen storage capacity, abundant reserves, low cost, and good reversibility.
Pure magnesium has a theoretical hydrogen storage capacity of 7.6 wt.%, but its practical capacity is limited by the slow kinetics and high thermodynamic stability of MgH 2 . Alloying magnesium with other elements can alter the hydrogen storage capacity, depending on the type and amount of the alloying elements.
Magnesium hydrides (MgH 2) have attracted extensive attention as solid-state H 2 storage, owing to their low cost, abundance, excellent reversibility, and high H 2 storage capacity. This review comprehensively explores the synthesis and performance of Mg-based alloys. Several factors affecting their hydrogen storage performance were also reviewed.
The integration of magnesium-based alloys with other hydrogen storage materials, such as metal hydrides and porous adsorbents, can also lead to the development of hybrid hydrogen storage systems with enhanced performance and flexibility.
Pistidda et al. successfully utilized magnesium industrial wastes of the AZ91 alloy and Mg-10 wt.% Gd alloy for the production of hydrogen storage materials . The measured reversible hydrogen storage capacity for the alloys AZ91 and Mg-10 wt.% Gd are 4.2 and 5.8 wt.%, respectively.
Magnesium (Mg)-based materials exhibit higher hydrogen-storage density among solid-state hydrogen-storage materials (HSMs). Highly reliable hydrolysis can be achieved using them for hydrogen production. They can also achieve the integration of hydrogen production and storage via the regeneration.
