Hydrogen storage properties and thermal stability of amorphous Mg70(RE25Ni75)30 alloys

► Amorphous Mg70(RE0.25Ni0.75)30 alloys were produced by melt spinning. ► The hydrogen desorption kinetics were in the order of Pr > La > Nd. ► The dehydrogenation activation energies of samples were low and Pr < La < Nd.
