Mitsubishi Heavy Industries announced on April 22 that it will mass-produce hydrogen using a High Temperature Gas Reactor (HTGR), a next-generation nuclear reactor. Mitsubishi will start a demonstration experiment in 2022, and aim for implementation in the first half of the 2030s. Both cost reduction and decarbonization can be achieved when hydrogen is produced from power generated at a nuclear power plant. Mitsubishi plans for the hydrogen to be used in steel and other industries that emit large amounts of carbon dioxide (CO2).
Hydrogen is produced at a power generation facility using an HGTR at the Japan Atomic Energy Agency (JAEA)’s High Temperature Engineering Test Reactor (HTTR). A full-scale hydrogen plant, to be connected to a HTGR, will be constructed after March 2024. Mitsubishi is expected to invest about 30 billion yen in the demonstration experiment up until 2030.
