Metal hydrides (MHs) can act as solid‐state hydrogen storage media, some of them having high gravimetric and volumetric hydrogen densities. The scientific community is currently putting significant efforts into developing hydride materials for onboard vehicular storage. MH materials can be used to generate hydrogen either directly by applying heat or indirectly by reacting with other hydrogen‐containing molecules, such as NaBH4 hydrolysis with water or LiAlH4 aminolysis with ammonia. MHs fall into three basic classes, namely simple hydrides, interstitial hydrides, and complex hydrides. Many metals and alloys are capable of storing large amounts of hydrogen and forming metal hydrides. Magnesium can be alloyed with many transition metals, and the resulting alloys can display promising hydrogen storage properties. One of the innovations developed in the metal hydride hydrogen storage field has been the use of destabilized materials to improve the thermodynamics of hydrogen storage reactions.
