Abstract
Liquid hydrogen is produced while reducing emission of carbon dioxide to the atmosphere. Provided is a liquid hydrogen production device including: a carbon dioxide cycle plant (), which includes a turbine () using a carbon dioxide fluid as a driving fluid, and is configured to drive the turbine () to generate motive power with use of a carbon dioxide cycle in which the carbon dioxide fluid discharged from the turbine () is increased in pressure and heated and is then re-supplied to the turbine (); and a liquefaction plant () configured to cool gaseous hydrogen by heat exchange with a refrigerant, to obtain liquid hydrogen. The motive power generated by driving of the turbine () is used as motive power to be consumed in the liquefaction plant ().
