This work is aimed at the development of simple and efficient technology for hydrogen generation by hydrolysis of magnesium hydride. The first part is focused on the experimental study of the influence of commonly used organic acids (acetic, citric and oxalic) in dilute aqueous solutions on the hydrolysis of commercial magnesium hydride powder. It was followed by study of hydrolysis, in pure water and aqueous solutions of citric acid, of MgH2 prepared by reactive ball milling in hydrogen of magnesium with additives of graphene-like materials (GLM) including the ones doped by nano-nickel catalyst (Ni/GLM). Finally, a method and apparatus for generating pressurised H2 by the hydrolysis of the materials on the basis of Mg or MgH2 in acidic solutions is briefly described.
