Lab-scale water-splitting hydrogen production test of modified hybrid sulfur process working at around 550$$^{circ}$$C

Takai, Toshihide ; Kubo, Shinji ; Nakagiri, Toshio ; Inagaki, Yoshiyuki

A thermo-chemical water-splitting hydrogen production process for sodium cooled FBR is under development based on Westinghouse sulfur process. A unique sulfur trioxide electrolysis is introduced in this process intended for the lowering the reaction temperature around the operation temperature of FBR (500$$sim$$550$$^circ$$C). Key engineering issues for eliminating barriers to industrialization of this process were examined using a laboratory-stage apparatus. Adequacy of the components structure and control method was confirmed from the test results. Further it was found that a continuous hydrogen production system based on this process is achievable.
