Study of Mg-based materials to be used in a functional solid state hydrogen reservoir for vehicular applications

Abstract

Powders mixtures of nanosized MgH2 and suitable additives, obtained by high energy milling, have been studied as materials to be used in a functional solid state hydrogen reservoir. A prototype of a two stages reservoir is under development (patent pending). The hydrogen release from the main stage, with high capacity Mg-based hydrides, is primed by a primer stage containing commercial hydrides able to operate at room temperature.
