Hydrogen storage by metal hydrides comprises an intermetallic alloy phase that has the capability to absorb and hold vast amounts of hydrogen by chemical bonding.1 An appropriate hydrogen storage matrix should have the capacity to absorb and release hydrogen without compromising the matrix structure. Metal hydrides are prepared by reaction between a metallic phase and hydrogen. When exposed to hydrogen at certain pressures and temperatures, these phases absorb large quantities of hydrogen gas and form the corresponding metal hydrides. If this is the scenario, the hydrogen is distributed compactly throughout the intermetallic lattice. Metal hydrides represent an exciting process of hydrogen storage, which is inherently safer than the compressed gas or liquid hydrogen storage. Additionally, some intermetallics (including metals and alloys) store hydrogen at a higher volume density than liquid hydrogen.
