Abstract

MgH2 has too high an operating temperature for many hydrogen storage applications. However, MgH2 ball-milled with Ge leads to a thermodynamic destabilisation of >50 kJ mol−1(H2). This has dramatically reduced the temperature of dehydrogenation to 130 °C, opening up the potential for Mg-based multicomponent systems as hydrogen stores for a range of applications.
