Proxima Fusion

Our cloud-based stellarator optimization and design framework, StarFinder, allows us to rapidly iterate on QI stellarator designs at lower costs and higher speed than ever before.

Proxima Fusion is developing quasi-isodynamic (QI) stellarators, a magnetic confinement approach in which toroidal currents cancel out to zero, resulting in uniquely robust features. W7-X is an invaluable prototype and testbed for this concept.

The scientific basis for QI stellarators has been spearheaded by our partners at the Max Planck Institute for Plasma Physics (for example, Helander & Nührenberg, PPCF 2009 and Goodman, Xanthopoulos, Plunk et al., PRX Energy 2024). We believe that QI stellarators using high-temperature superconducting (HTS) magnets offer the clearest path to putting fusion on the grid.

Our peer-reviewed fusion power plant concept, Stellaris, has been published in Fusion Engineering and Design. Stellaris is the first stellarator concept to integrate electromagnetic, structural, thermal, and neutronics simulations, resulting in a fully coherent design.

We believe that fusion has the potential to provide safe, clean, and abundant energy to humanity. That’s why we're taking the technical approach with the clearest path to grid deployment.

Our team of 150+ world-class scientists, engineers, and operators has been assembled from some of the world’s most innovative companies and institutions, including the Max Planck IPP, MIT, SpaceX, Tesla, McLaren, Google X, TUM, EPFL, Stanford, KIT, Harvard, and Cambridge.

We work closely with world-leading fusion research institutions, including the Max Planck Institute for Plasma Physics (IPP) and Karlsruhe Institute of Technology (KIT), leveraging decades of research and experience from the European fusion ecosystem.

Martin Kubie is Chief Engineer and co-founder of Proxima Fusion. Martin has architected and led engineering projects for companies at the frontier of science and technology including in Formula 1 for McLaren Racing and at the Google X spin-off Wing, deploying one of the world's largest fleets of autonomous delivery drones. At Proxima, Martin is now leading the engineering teams that combine rapid prototyping with simulation- and ML-driven design.

Jonathan Schilling is Head of Labs and co-founder of Proxima Fusion. Jonathan has hands-on experience in building advanced models for magnetic confinement fusion experiments, with expertise including experimental plasma physics, theoretical plasma physics, electrical engineering and mechanical engineering. Prior to co-founding Proxima Fusion, Jonathan was a Doctoral Researcher at the Max Planck Institute for Plasma Physics (IPP), where he analyzed plasma behavior in the record-breaking experiments of Wendelstein 7-X.

We are tackling the full breadth of stellarator power plant design, focusing on a simulation-first and rapid prototyping-led approach.

We are working with energy companies and key technologies suppliers across Europe to bring this vision to reality.
