Proxima Fusion GmbH is a fusion energy company based in Munich. It is developing the first generation of fusion power plants based on quasi-isodynamic (QI) stellarators, an approach to magnetic confinement fusion that aims to provide a path to commercial energy production.
The company's technical work spans stellarator optimization, computational design, and high-temperature superconducting (HTS) magnet technology. Its engineering approach is simulation-first, incorporating machine-learning-enabled engineering, integrated modeling workflows, and plasma behavior prediction to advance its designs.
Proxima Fusion's primary product concept is Stellaris, a peer-reviewed, first-of-a-kind design for a commercial stellarator power plant. The company operates at the intersection of advanced physics, superconducting technology, and computational engineering to translate stellarator research into a viable energy technology.
