| Outline of Final Research Achievements |
Mg hydride which has the high volumetric density of hydrogen is an attractive option to store energy because of its light weight and low material costs. However, the Mg-H system has thermodynamic and kinetic limitations associated with hydrogen absorption and desorption processes: the high stability of the MgH2 phase and the slow diffusion of hydrogen in Mg and MgH2 at moderate temperatures and pressures. Nanometer-sized Mg hydride clusters may form in a self-organized way by the hydrogenation of a non-equilibrium Mg-Ti alloy. In this study we have synthesized Mg-Ti-X (X: Cr, Mn) and Mg-Fe-Si hydrides and the Mg hydride is destabilized by the interface energy.
