Abstract: To reduce the emission of carbon dioxide and improve the energy efficiency in a hydrogen supply system. The hydrogen supply system (1) comprises: a reformer (5) for performing steam reforming of a hydrocarbon; a shift reaction unit (6) for producing a gas containing hydrogen and carbon dioxide by causing a water gas shift reaction of a gas obtained from the reformer; a first absorber (36) for absorbing the carbon dioxide contained in the gas obtained from the shift reaction unit in an absorption liquid; a hydrogenation reaction unit (8) for producing a hydrogenated aromatic compound by causing a hydrogenation reaction of an aromatic compound with a gas that has passed through the first absorber; and a regenerator (37) for separating the carbon dioxide from the absorption liquid by re-circulating the absorption liquid from the first absorber and heating the absorption liquid with heat generated from the hydrogenation reaction.
