Proxima Fusion - Building stellarators to power the future — •Jonathan Schilling — Proxima Fusion, Munich, Germany

Proxima Fusion is Europe’s fastest-growing fusion company, building the first generation of fusion power plants using quasi-isodynamic (QI) stellarators - the clearest, most robust path to putting fusion on the grid. Proxima Fusion is the first spin-out from the Max-Planck-Institute for Plasma Physics and builds on the record-breaking successes of the Wendelstein 7-X stellarator. Its roadmap towards the peer-reviewed Stellaris commercial power plant concept progresses through demonstration milestones including the Stellarator Model Coil and the Alpha demonstration stellarator slated to achieve net energy gain in the early 2030s, culminating in a first-of-a-kind grid-connected fusion power plant within the 2030s. Assembling a world-class team from institutions such as Max Planck IPP, MIT, Google[X], SpaceX, and leading universities, and backed by significant public and private investment, Proxima Fusion accelerates fusion from scientific achievement to industrial-scale reality. Proxima Fusion collaborates across the European fusion ecosystem to solve physics, engineering, and systems-integration challenges, advancing stellarator design, high-performance magnets, and rapid prototyping toward fusion’s transformative impact on global energy. This talk will give an overview of Proxima Fusion’s roadmap and highlight recent achievements.
