[Problem] To improve thermal efficiency in a manufacturing device for hydrogen and synthetic natural gas. [Solution] Provided is a manufacturing device (1) for hydrogen and synthetic natural gas wherein: the manufacturing device comprises a synthetic natural gas production device (2) that produces synthetic natural gas from hydrogen and carbon dioxide through a reverse shift reaction and a methanation reaction, and a hydrogen production device (3) that produces hydrogen from a hydrogenated aromatic compound through a dehydrogenation reaction; and in order to use the reaction heat of the methanation reaction, which is an exothermic reaction, in the dehydrogenation reaction, which is an endothermic reaction, the heat is supplied to the hydrogen production device from the synthetic natural gas production device. |
