| 1. A method of reversibly storing hydrogen, the method comprising:
providing a mixture comprising a stable hydrogen storage hydride and a destabilizing hydride, wherein said stable hydride
is capable of releasing hydrogen at a first energy level (E1); and
reacting said stable hydride with said destabilizing hydride to provide at least a first hydrogen storage material and to
release hydrogen at a second energy level (E2); wherein E2 is less than E1, and exposing the first hydrogen storage material to hydrogen to form the stable hydrogen storage hydride and the destabilizing
hydride.
