Stellaria’s innovative project receives a key boost as the French startup, born out of the collaboration between CEA and Schneider Electric, has closed a €23 million funding round aimed at accelerating the development of its molten salt reactor. With this capital, Stellaria plans to finalize its ambitious timeline that foresees the first fission reaction in 2029 and commercial deployment in 2035.
International support and industrial strategy
Investors backing this new phase include the U.S. fund At One Ventures and the French firm Supernova Invest, along with long-standing partners such as Schneider Electric, CEA Investissements, Exergon and Technip Energies. This financial backing will enable the company to double its workforce and strengthen its laboratory in Grenoble, thus consolidating its position as a key player in the industrial decarbonization.
The reactor that Stellaria is developing is based on molten salts with fast neutrons, a technology that promises passive safety, reduced capital costs and flexibility in fuel use. These features make it a practical option for energy-intensive industries such as steel, chemicals or artificial intelligence-powered data centers.
Molten salt reactor will ensure stable power
The French startup’s goal is to ensure reliable and predictable electricity at predictable prices for electro-intensive sectors. Its design will allow it to operate for more than 20 years without refueling and with the capacity to destroy more waste than it generates, offering a next-generation energy solution.
The favorable regulatory context in France under the France 2030 program program paves the way for Stellaria to submit its application for authorization to the nuclear safety authorities. The planned industrial demonstrator will be the next step in its commercial expansion.
With the support of industrial players such as Schneider Electric and Technip Energies, Stellaria aims to consolidate its position as a reference in clean, low-carbon next-generation nuclear energy.
