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. |
