About Proxima Fusion
Proxima Fusion is a fusion energy company developing power plants based on quasi-isodynamic (QI) stellarators with high-temperature superconducting magnets. It was spun out of the Max Planck Institute for Plasma Physics in 2023 — the institute's first-ever spin-out — and builds directly on the results of the Wendelstein 7-X experiment, the world's most advanced stellarator. Its roadmap runs through the Stellarator Model Coil demonstration magnet in 2027 to Alpha, a net-energy demonstrator planned near Munich for the early 2030s, followed by Stellaris, a first commercial fusion power plant planned for the site of RWE's decommissioned nuclear plant in Gundremmingen, Bavaria, under an agreement with RWE, the Free State of Bavaria and the Max Planck Institute.
