Building stellarators to power the future

Proxima is building the first generation of stellarator fusion power plants – and the industrial platform required to deliver them.

From integrated design and advanced magnet technology to manufacturing, supply chains and program delivery, we are turning Europe’s stellarator advantage into commercial fusion power plants.

Our Vision

A fusion-powered future in which abundant, reliable and clean energy expands what humanity can achieve.

We are pursuing the approach that offers the clearest path to continuous, commercially viable fusion power: QI-HTS stellarators.

Our Programs

From integrated design and advanced magnet technology to manufacturing, supply chains and program delivery, we are turning Europe’s stellarator advantage into commercial fusion power plants.

Alpha

Alpha is Proxima’s demonstration stellarator in which new technologies, manufacturing capabilities, and industrial partnerships converge.

Stellaris

Stellaris is Proxima's concept for a first commercial fusion power plant. Its requirements set our goals, and shape the technologies and industrial capabilities we are developing today.

Europe’s fusion industry

Proxima Fusion develops stellarator technologies as integrated systems. Commercial power plant requirements shape our R&D moonshots, the hardware we build and test, and the industrial capabilities we establish.

Proxima works through connected cycles of simulation, manufacturing, testing and integration.

Europe has world-class strengths in stellarator science, advanced engineering and manufacturing. Proxima Fusion is bringing those strengths together – and building new capabilities alongside our partners in the Alpha Alliance – to deliver Alpha, Stellaris, and future fusion devices.
