Japan Atomic Energy Agency (JAEA)

A collaborative initiative between JAEA and Mitsubishi Heavy Industries to develop and demonstrate hydrogen production using heat from high-temperature gas-cooled reactors via the iodine-sulfur (IS) process. The project aims to establish Japan as a global pioneer in this technology.

JAEA and MHI are working with research institutions and international partners to prepare demonstration facilities for nuclear-assisted hydrogen production that could become models for deployment in hydrogen-hungry nations globally.

An efficient thermochemical cycle for hydrogen production that leverages high-temperature heat from HTGRs. The process operates in a closed cycle with no carbon emissions involved.

A method combining nuclear reactor heat with hydrogen production technology to create low-carbon hydrogen without relying on electricity generation or fossil fuels. This approach decouples hydrogen production from electricity generation.

Advanced nuclear reactors that operate at significantly higher temperatures than traditional light-water reactors, making them ideal for industrial heat applications like hydrogen production. HTGRs are designed with inherent safety features including graphite moderators, helium coolant, and passive heat removal systems.
