Jimmy Energy is developing a High-Temperature Gas-Cooled Reactor specifically for industrial process heat — targeting hard-to-decarbonise industrial sectors such as chemicals, cement, and steelmaking. The French nuclear safety authority has begun formal scrutiny of Jimmy Energy's design under the France 2030 investment programme, representing a landmark transition from pure R&D to credible commercialisation. First-of-a-kind deployment targets mid-2030s.
