A reversible hydrogen storage composition having an empirical formula of: Li.sub.(x+z)N.sub.xMg.sub.yB.sub.zH.sub.w where 0.4.ltoreq.x.ltoreq.0.8; 0.2.ltoreq.y.ltoreq.0.6; 0<z.ltoreq.0.4, x+y+z=1 and "w" varies from 0 to 2x+2y+4z. This composition shows greater low temperature reversible hydrogen storage compared to binary systems such as MgH.sub.2--LiNH.sub.2.
