Renewable energy source is wind, solar etc. The use of hydrogen as fuel reduced eliminate the carbon emissions. sodium alante is used to store the hydrogen due to high capicity. The purpose of this work is to investigate the effect of transition metal (Zr, V, Ni) on hydrogen desorption of NaAlH4.The samples prepared doped catalyst Zr, Ni, V and TiCl3with NaAlH4 under argon atmosphere using ball milling and hand milling for 30 minute. The transition metals is improve the kinetics of the hydrogen desorption in NaAlH4 and the rate of desorption increased with increasing the amount of catalyst . Structural properties were characterized by XRD. The maximum hydrogen capacity is 5.2 wt % . Kinetic measurement was taken by PCT.

Keywords : Sodium Alanate, Hydrogen, Kinetics, Catalyst, Ball Milling , XRD.
