A hydrogen storage material and process is provided in which catalyzed alkali borohydride materials and partially substituted borohydride materials are created and which may contain effective amounts of catalyst(s) which include transition metal oxides, halides, and chlorides of titanium, zirconium, tin, vanadium, iron, cobalt and combinations of the various catalysts and the destabilization agents which include metals, metal hydrides, metal chlorides and complex hydrides of magnesium, calcium, strontium, barium, aluminum, gallium, indium, thallium and combinations of the various destabilization agents. When the catalysts and destabilization agents are added to an alkali borodydride such as a lithium borohydride, the initial hydrogen release point of the resulting mixture is substantially lowered. Additionally, the hydrogen storage material may be rehydrided with weight percent values of hydrogen of at least about nine percent.
