Demonstration of Clean Hydrogen Production using nuclear heat at Fast Breeder Test Reactor (FBTR), IGCAR

On 26 June 2026, IGCAR demonstrated the world’s first production of clean hydrogen using nuclear heat at the Fast Breeder Test Reactor (FBTR). The Copper‑Chlorine thermochemical cycle, developed by BARC, was coupled with the FBTR’s secondary sodium heating loop to generate carbon‑free hydrogen. The Ministry of Atomic Energy highlighted that this nuclear‑assisted hydrogen process can provide a stable baseload alternative to renewable‑powered electrolysis, supporting co‑generation of electricity and hydrogen, and aligning with India’s National Green Hydrogen Mission and Net‑Zero targets. The achievement also reinforces indigenous clean‑energy capabilities and the broader three‑stage nuclear programme aimed at long‑term energy security.
