Proxima Fusion, the European nuclear fusion startup, has unveiled together with its partners the concept for its innovative commercial fusion plant, Stellaris. Designed to operate continuously and reliably, Stellaris represents a breakthrough in the development of clean and safe energy , based on quasi-isodynamic (QI) stellarizer technology.
An integrated commercial fusion plant concept
Stellaris ’ design is based on the advances made with the Wendelstein 7-X (W7-X) experiment in Germany, the most advanced QI stellarator to date. This approach overcomes the limitations of traditional tokamaks by eliminating plasma instabilities, ensuring a stable and continuous energy supply.
By applying high-temperature superconductors (HTS), Stellaris is able to generate stronger magnetic fields and significantly reduce the size of reactors, optimizing efficiency and reducing construction and operating costs.

The project is the result of a collaboration between Proxima Fusion and the Max Planck Institute for Plasma Physics (IPP), which has been driving research and development in this field for decades. In addition, the Proxima Fusion engineering team includes experts from companies such as Google, Tesla, McLaren and SpaceX, accelerating the application of advanced technologies in fusion reactor design.
Details of the Stelaris concept were published in Fusion Engineering and Design magazine.
Goal: Unlimited and secure energy in the next decade
Proxima Fusion plans to build a demonstration reactor, Alpha, by 2031, with the goal of delivering fusion power to the grid in the 2030s. This development represents a decisive step toward commercializing nuclear fusion as a viable source of clean and safe energy.
The Stellaris concept has already been validated through electromagnetic, structural, thermal and neutron simulations, ensuring that it meets key physical and engineering constraints. With this innovation, Proxima Fusion reaffirms its commitment to leading the global energy transition through commercial nuclear fusion.
