Abstract: A hydrogen storage vessel (20, 30) comprising an internal volume (21, 31) and an outer shell (32, 32) having an interior wall confining the internal volume (21, 31) containing a hydrogen storage material. The hydrogen storage vessel further comprises a plurality of internal cooling channels (23, 24, 25, 26, 33, 34, 35, 36) communicating with a source of heat transfer medium. The internal cooling channels comprising first internal channels (23, 33) and second internal channels (24, 34, 25, 35, 26, 36) whereby the first internal channels (23, 33) are closer to the outer shell than the second internal channels. A method of absorbing hydrogen is also disclosed including the steps of subjecting the hydrogen storage material to temperature and pressure conditions to initiate hydrogen absorption while supplying hydrogen to the storage vessel; and cooling the hydrogen storage material in proximity to the interior wall to create a lower density of hydrogen storage material in the region in proximity to the interior wall of the internal volume.

Abstract: A range of alloys of Mg and at least one of Cu, Si, Ni and Na alloys that is particularly suitable for hydrogen storage applications. The alloys of the invention are formed into binary and ternary systems. The alloys are essentially hypoeutectic with respect to their Cu and Ni contents, where one or both of these elements are present, but range from hypoeutectic through to hypereutectic with respect to their Si content when that element is also present. The terms hypoeutectic and hypereutectic do not apply to Na if it is added to the alloy. The alloy compositions disclosed provide high performance alloys with regard to their hydrogen storage and kinetic characteristics. They are also able to be formed using conventional casting techniques which are far cheaper and more amenable to commercial use than the alternative ball-milling and rapid solidification techniques which are much more expensive and complex. Each of the individual binary Mg-E systems, where E = Cu, Ni or Si, forms a eutectic comprising of Mg metal and a corresponding Mg x E y intermetallic phase.
