The invention provides a hydrogen storage material consisting essentially of a hydride of lithium and magnesium, the material having the general formula: LiMgHwherein: (i) x is in the range of from 0.17 to 0.93; (ii) y is in the range of from 0.07 to 0.83; and (iii) n is not greater than (x+2y); with the proviso that n is not (x+2y) when (a) x=y; (b) x=2y or (c) 2x=y. Methods of producing the hydrogen storage material and its use to store hydrogen reversibly or irreversibly are also provided.

Hydrogen storage materials

A doped hydrogen storage material according to the general formula:MgBMHwherein: The doped hydrogen storage materials are used for storing hydrogen, and also disclosed is a method for reversibly desorbing and/or absorbing hydrogen.

Doped hydrogen storage material

The present invention relates to a doped hydrogen storage material according to the general formula:MgBMHwherein: (i) the ratio of x/y is in the range of from 0.15 to 1.5; (ii) z is in the range of from 0.005 to 0.35; (iii) x+y+z equals 1; (iv) M=is one or more metals selected from the group of selected Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn; (v) n is no more than 4y; and wherein x/y does not equal 0.5 and at least part of the doped hydrogen storage material is amorphous. The present invention further relates to the use of doped hydrogen storage materials according to the invention for storing hydrogen and a method for reversibly desorbing and/or absorbing hydrogen.
