A review of catalyst-enhanced magnesium hydride as a hydrogen storage material

•Detailed review of catalytic additives for enhanced hydrogen sorption properties of magnesium hydride•Effect of additives on activation energy, kinetics and thermodynamics•The role of different additives on different kinetic rates of the reaction

Magnesium hydride remains an attractive hydrogen storage material due to the high hydrogen capacity and low cost of production. A high activation energy and poor kinetics at practical temperatures for the pure material have driven research into different additives to improve the sorption properties. This review details the development of catalytic additives and their effect on the activation energy, kinetics and thermodynamic properties of magnesium hydride.
