Hexana is developing an energy platform combining modular sodium-cooled fast reactors and a thermal storage system. It is a subsidiary of the CEA (French Alternative Energies and Nuclear Energy Commission). The startup targets industrial consumers of high-temperature heat and decarbonized electricity on a large scale. Its power plant has the ability to store heat at high temperatures before its eventual conversion into electricity. This capability enables more flexible energy production and adaptability to fluctuating demand without relying on fossil fuels or reactor load adjustments.
