We are a European startup building the first generation of fusion power plants using quasi-isodynamic (QI) stellarators—the clearest, most robust path to putting fusion on the grid.
Stellarators are the power plants of the future, promising clean, safe, and abundant fusion energy for all.
We're leveraging decades of research in magnetic confinement fusion, combining advances in stellarator optimization, computational design, and high-temperature superconducting (HTS) magnet technology with the expertise behind the record-breaking W7-X stellarator at the Max Planck Institute for Plasma Physics (IPP).
The world’s most advanced optimized stellarator, W7-X, was completed in 2015 by the Max Planck Institute for Plasma Physics (IPP) and has since repeatedly broken key performance records.
Proxima brings together fusion scientists from the Max Planck Society with experts across engineering and computer science as the first-ever spin-out from IPP.
QI stellarators can be designed to run stably in continuous operation, a key advantage over tokamaks.
The QI configurations pioneered at the Max Planck Institute for Plasma Physics ensure that no electric currents persist in the toroidal direction in the confined plasma, eliminating current-driven disruptions.
In recent years, public research has demonstrated that the historical drawbacks of stellarators—such as low heat and fast particle confinement—can now be overcome.
The path to QI stellarator fusion power plants is now open.
High-temperature superconducting (HTS) magnets are revolutionizing magnetic confinement fusion.
Leveraging HTS technology requires detailed engineering analysis, enabled by modern computational design capabilities.
In partnership with the industry that has led the development of W7-X and ITER, we are collaborating with partners, companies, and suppliers across the continent to bring Europe to the forefront of fusion R&D.
Stellarators were exceedingly difficult to design in the past, until the advent of supercomputing.
The vast number of free parameters in stellarator designs used to make them impossible. No more.
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.
