    Hydrogen is considered to be clean fuel for various energy sources in the near future. One of technical problems in this area is its effective storage. MgH2 is very perspective material whose main advantage is high hydrogen storage capacity (theoretically 7.6 wt. % H2). However, there are negative features of this material as a hydrogen storage medium: before all, it is its poor hydrogen de-sorption kinetics. Therefore, much effort has been devoted in the past to find out possible ways how to enhance the MgH2 de-sorption rate and how to shift this material close to technical applications. It is known that nickel and Mg2Ni enhance hydrogen de-sorption from MgH2. This paper continues our previous works on hydrogen de-sorption from Mg-Ni –based materials. It is devoted to the investigation of separate catalytic effect of Mg2NiH4 and Mg2Ni upon the hydrogen de-sorption from the principal component of the material - MgH2. It was found that catalytic efficiency of Mg2NiH4 is much higher than that of Mg2Ni.
