Abstract: Provided is an operation management system configured to manage delivery of a raw material from a raw material production base where the raw material including a hydride is produced to a plurality of dehydrogenation bases where the raw material is subjected to a dehydrogenation reaction to obtain a hydrogen-containing gas. The operation management system includes: an information acquisition unit configured to acquire first information on a dehydrogenation status in the plurality of dehydrogenation bases; and a delivery plan creation unit configured to create a delivery plan for delivering the raw material to the plurality of dehydrogenation bases on the basis of the first information.

Abstract: Provided is a hydrogen supply system that supplies hydrogen. The hydrogen supply system includes: a dehydrogenation reaction unit that subjects a raw material including a hydride to a dehydrogenation reaction to obtain a hydrogen-containing gas; a circulation system that circulates a reaction inactive fluid to the dehydrogenation reaction unit; and a control unit that controls the hydrogen supply system. The control unit circulates the reaction inactive fluid with the circulation system in a case where production of the hydrogen-containing gas in the dehydrogenation reaction unit is stopped.
