Description
Proxima Fusion – founded in 2023 and based in Munich, Germany – is a startup developing commercially scalable fusion energy using quasi-isodynamic (QI) stellarator technology. The company now employs more than 90 people across sites in Munich, the Paul Scherrer Institute near Zurich, and the Culham fusion campus near Oxford.
A spin-out from the Max Planck Institute for Plasma Physics (Max Planck IPP) – the institution behind the world’s most advanced optimised stellarator, Wendelstein 7-X – Proxima maintains close collaboration with Max Planck IPP as well as a broad network across the European fusion ecosystem. Key partners include the Karlsruhe Institute of Technology, Forschungszentrum Jülich, the Paul Scherrer Institute, and several private-sector contributors.
In early 2025, the company unveiled Stellaris, its commercial stellarator power plant concept. Proxima aims to complete its Stellarator Model Coil by early 2027, bring its Alpha demonstration device online by 2031, and introduce the first commercially viable Stellaris power plant in the mid- to late 2030s.
