A truly stellar source of power.

We are a European startup building the first generation of fusion power plants using QI stellarators.

We build upon decades of advancements in magnetic confinement fusion with some key innovations that will push fusion onto the grid.

We combine advances in stellarator optimization, computational design and superconductivity with the expertise behind the W7-X stellarator at the Max Planck Institute for Plasma Physics.

What we’re doing

Fusion has many obstacles. We believe QI stellarators will overcome them.

QI stellarators will be the power plants of the future, complementing renewables and offering clean, abundant and safe energy for all.

Wendelstein - 7X

Standing on the shoulders of Giants

The world’s most advanced optimized stellarator, W7-X, was completed in 2015 by the Max Planck Institute for Plasma Physics and has since repeatedly broken key performance records.

We bring together fusion scientists from the Max Planck Society with experts across engineering and computer science.

We are the first ever fusion spin-out from the Max Planck Institute for Plasma Physics.

Our Technology


Quasi-Isodynamic Stellarators

QI Magnetic Field Contours

Optimized, quasi-isodynamic stellarators are unique amongst fusion devices due to their intrinsic stability and potential for continuous operation.

The quasi-isodynamic configurations pioneered at the Max Planck Institute for Plasma Physics ensure that no electric currents persist in the toroidal direction in the confined plasma.

This has far reaching consequences for the handling of power exhaust, and leads to the complete absence of current-driven disruptions (sudden losses of confinement) that affect tokamaks.

In recent years, public research has demonstrated that the historical drawbacks of stellarators (e.g. low heat and fast particle confinement) can now be overcome. The path to QI stellarator power plants is now open.


High-Field Magnets

High Temperature Superconductors (HTS)

High-temperature superconductors are revolutionizing magnetic confinement fusion.

Leveraging this 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 bringing Europe to the forefront of fusion R&D. 


Simulation-First Approach

Virtual Prototype Environment

Stellarators were exceedingly difficult to design in the past, until the advent of modern computing. 

The vast number of free parameters in stellarator designs used to make them impossible. No more.

We are building a cloud-based stellarator optimization and design framework.

This allows us to rapidly iterate over magnetic configurations and engineering designs at lower costs and higher speed than ever before.
