Thermochemical hydrogen production process is the technology to decompose water with high efficiency by combination of some chemical reactions, using thermal energy at a lower temperature than that required for direct thermal decomposition. The Iodine-Sulfur (IS) process is one of the thermochemical processes, which is composed of three chemical reactions. Japan Atomic Energy Agency (JAEA) has been developing the IS process to demonstrate nuclear hydrogen production by connecting to a High Temperature Gas-cooled Reactor (HTGR), which can supply a high temperature heat of 950C. Furthermore, in order to use a solar heat as a thermal energy, the development of membrane reactor technology is underway by industry-university cooperation in the Cross-ministerial Strategic Innovation Promotion Program (SIP) of Cabinet Office. This lecture presentation describes the current status of development on the IS process.
