Development of hydrogen production technology using a high-temperature gas-cooled reactor at JAEA

Myagmarjav, O.  

The high-temperature gas-cooled reactor (HTGR) has excellent safety features and can generate heat above 900$$^{circ}$$C, which can be used not only for power generation but also for effective heat utilization including low-cost carbon-free hydrogen production. JAEA possesses the high temperature engineering test reactor equipped with world-leading technologies, which has achieved an operation of world highest 950$$^{circ}$$C for 50 days. Also, JAEA succeeded in producing hydrogen continuously for 150 hours using a thermochemical iodine-sulfur process herein necessary heat was supplied from electric heaters instead of heat from HTGR. JAEA will continue to develop innovation technologies for realizing decarbonization and hydrogen society.
