Magnesium-based hydrogen storage materials have the advantages of high hydrogen storage capacity, abundant magnesium resources and low cost, and are considered to be of promising application prospects. In recent years, numerous researches have focused on improving the performance of hydrogen supply by pyrolysis/hydrolysis of MgH₂ and many good achievements have been obtained. Based on the recent research progress, this paper summarizes the effects of the material/ structure modification and the reaction conditions on pyrolysis/hydrolysis performance of the magnesium-based hydrogen storage materials, and expounds the relationship between composition-microstructure-properties of solid Mg-based hydrogen storage materials. Meanwhile, the Mg-based hydrogen storage systems and their industrial applications are summarized. At last, the current results of the solid state Mg-based hydrogen storage are summarized and some suggestions for the future investigations are proposed.
