The hydride materials are very promising materials for the near-term perspective. The main hydride materials applications in terms of the properties required are following [1-4]: 1. Hy-storage application. Stationary storage usually implies bulk storage and large amounts of alloy (desire easy requirements for the one-time activation, good resistance to gaseous impurities, pressure-composition-temperature (PCT) properties should be roughly in the ambient temperature and pressure area, low alloy cost tends to be an important property). 2. Application for hydrogen compression. The compression of gaseous H2 using thermal swings of hydride beds is an open-ended process and generally requires the alloy to have good impurity resistance (impure H2 pumped) and cyclic stability (high temperatures involved). H/D cycling is relatively fast, so good kinetics and heat transfer are desired. If rapid cycling can be achieved, then relatively small inventories of alloy are needed and alloy cost becomes secondary to other properties. 3. Application for hydrogen separation. Separation can be divided into two classes: (I) H2 separation from other gases; and (II) H-isotope separation. The first class can be further divided into gross separation, purification and gettering. All three subclasses require impurity tolerance, tailored PCT properties and other properties that are application specific. 4. There are a number of lesser-known hydride applications: liquid H2 control and boiloff capture, cryocooling, chemical catalysis, ammonia synthesis, methane synthesis, diamond synthesis [5], permanent magnet production and others. The biggest commercial application is the metal hydride battery [6]. [1] Sandrock G. A panoramic overview of hydrogen storage alloys from a gas reaction point of view. J.
