Potential of the HTGR hydrogen cogeneration system in Japan

Nishihara, Tetsuo ; Mori, Tomoaki; Kunitomi, Kazuhiko 

Japan Atomic Energy Agency (JAEA) has been carried out the design study of the HTGR hydrogen cogeneration system (GTHTR300C). GTHTR300C is 600MWth and the hydrogen production plant utilizes 370MW to supply 52,000m$$^{3}$$/h of hydrogen. Industrial hydrogen production capacity in Japan will decrease by 15 Bm$$^{3}$$/y in 2030. And the hydrogen demand for fuel cell vehicle in 2030 is estimated at 15Bm$$^{3}$$/y at a maximum. This hydrogen shortage is a potential market for the GTHTR300C. Hydrogen cost of the GTHTR300C is estimated at 20.5 JPY/m$$^{3}$$ which has a economic conpetitiveness against other industrial hydorgen processes. 38 units of the GTHTR300C can supply a half of this shortage which accounts for the 33% of hydrogen demand for FCV in 2100.
