Abstract: On a global scale, hydrogen storage is getting increasing attention as an alternative energy source technology in contrast to conventional fuels. A pivotal component in this work is the utilisation of metal hydrides, which need to be meticulously obtained to optimise their storage and sensing capabilities. This paper comprehensively reviews various metal hydrides and discusses the consideration of catalysts and alloys. The review also investigates a comparative analysis of different metal hydrides in terms of their absorption and desorption characteristics, encompassing kinetics, storage capacity, cycle stability, operational temperature, and pressure requirements. Lastly, the review outlines future research directions and recommendations.

Keywords: absorption; catalysts; desorption; hydrogen energy; hydrogen storage; metal hydrides.
