Metal hydrides are considered to be excellent candidates for hydrogen storage applications because of their high hydrogen volumetric density (sometimes higher than in liquid hydrogen) and the possibility to absorb and desorb hydrogen with a small change of hydrogen pressure.

One or the main problem to be solved for utilization of metal hydrides in practical applications is cost of the material. In this presentation we will discuss three ways to reduce cost of metal hydrides: element substitution, addition of a second phase, and use of severe plastic deformation techniques.

Likewise, three types of metal hydrides will be discussed: Titanium-based BCC alloys, magnesium alloys and TiFe alloys.

We will show that, depending on the alloy considered, different strategies should be used I order to reduce the hydride cost.

One of the main aspect covered in this talk will be the improvement of the first hydrogenation kinetics, the so-called activation process. Specific examples on each type of alloy will be presented.
