The thermochemical water splitting iodine-sulfur (IS) process has potential for producing a large amount of hydrogen without restriction of resources and CO $_{2}$ emission in the upcoming hydrogen society. The IS process harnesses heat energy in ranges of temperature, which is generated by High Temperature Gas-cooled Reactors (HTGRs) or solar energy. For application of solar energy, innovative membrane techniques are required to recover total thermal efficiency because temperature (ca. 600 $^{circ}$ C) of heat derived from the solar energy is lower than that of HTGRs (ca. 900 $^{circ}$ C). This paper summarizes current R&D of key devices of membranes and catalysts, and of process evaluation.
