Stavila, Vitalie; Klebanoff, Leonard E.

A method and a system is provided for obtaining solid-state hydrogen storage and release in materials with at least theoretical loaded hydrogen densities of 11 wt % or greater that can deliver hydrogen and be recharged at moderate temperatures enabling incorporation into hydrogen storage systems suitable for transportation applications. These materials comprise ternary boride materials comprising certain light transition metals and alkaline or alkaline earth metals, and ideally have no or very little phase separation. A process of making these materials is also provided.
