To provide moving bed type hydrogen storage alloy utilization facilities which introduce the power meeting an environment change from storage vessels in compliance with the environmental change and state change of storage hydrogen alloys and its utilization method.

This hydrogen occlusion alloy utilization facilities having the moving bed system has the plural hydrogen storage alloy storage vessels 7, 7', 7". The hydrogen storage alloy compositions used in the hydrogen occlusion alloy storage vessels are held at the different compositions by the plural hydrogen storage alloy storage vessels disposed at the equipment. Further, lubricants for accelerating the flow of the hydrogen storage alloys and heat transfer accelerators for accelerating heat transfer are held therein.
