HYDROGEN PRODUCTION SYSTEM, HYDROGEN STORAGE AND TRANSPORTATION SYSTEM PROVIDED WITH THE SAME, AND HYDROGEN PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To stably obtain energy consumed for production of raw material water for water electrolysis at a low cost when hydrogen used for hydrogenation of aromatic compounds is produced by water electrolysis.SOLUTION: A hydrogen production system 1 comprises: a power generator 11 that generates power using renewable energy; a water electrolysis device 12 that produces hydrogen by electrolysis of raw material water using the power; a hydrogenation device 14 that adds the hydrogen to aromatic compounds by a hydrogenation reaction to generate organic hydride; and a fresh water generator 13 that produces the raw material water by an evaporation method. The fresh water generator 13 is constituted to use heat of reaction in the hydrogenation device 14 in the production of the raw material water.
