Munich Start-up Proxima Fusion Raises 411 Million Euros for Fusion Reactor

From Max Planck Spin-off to Unicorn

The demonstration reactor, named "Alpha," is to be built in Garching near Munich in the early 2030s. Initial components are already being manufactured; according to the company, the first magnet is to be completed by the end of next year. The costs for "Alpha" alone are estimated at around two billion euros.

The funding round simultaneously fulfilled the conditions for the Free State of Bavaria – as already agreed in February – to provide an additional 400 million euros. Proxima Fusion is also hoping for a federal funding tender for the project in the fall. This would significantly broaden the public funding landscape.

"Alpha" Reactor in Garching and Power Plant in Gundremmingen

In the medium term, the company plans to build a commercial fusion power plant in Gundremmingen in Franconia, which is to feed electricity into the grid by the end of the 2030s. However, information on the location varies: one source places the project in Gundremmingen in Swabia, without resolving this discrepancy further.

Co-founder and CEO Francesco Sciortino sees the capital round as a signal for Europe's competitiveness: "Die internationale Investorengemeinschaft hat ein starkes Signal gesendet: Sie vertraut nicht nur auf die wissenschaftliche Exzellenz Europas, sondern auch auf unsere Fähigkeit, daraus weltweit wettbewerbsfähige Industrieunternehmen aufzubauen." He further explained: „Diese Finanzierung zeigt, dass Deutschland und Europa in der Lage sind, internationales Kapital für strategische Zukunftstechnologien zu mobilisieren."

Voices from the Company

Sciortino also sees fusion technology as an industrial opportunity on a large scale. Fusion technology has the potential „eine ähnliche wirtschaftliche Bedeutung zu erlangen wie einst die Automobilindustrie". The comparison with Germany's former key industry is programmatic: Proxima Fusion sees itself as a global leader in stellarator technology.

Fusion as a Global Future Technology

Fusion energy is based on the merging of atomic nuclei – the same process that powers the sun and stars. Compared to conventional nuclear fission, it is considered cleaner, and unlike fossil fuel power plants, it does not cause direct CO2 emissions. However, the technology is not yet commercially mature; billions have already flowed into fusion start-ups in the USA and China worldwide.

Against this backdrop, Proxima Fusion positions itself as one of the few European companies that seriously intends to keep pace in the international race for the first commercially usable fusion energy. The valuation of more than 2.4 billion euros and unicorn status are regarded in the start-up world as markers that professional investors believe in the project's success despite the long-term risks.

With the combination of private risk capital, state funding from Bavaria, and possible federal funding in the fall, Proxima Fusion has a piece-financing profile that is unusual in Europe for an industrial start-up. If "Alpha" demonstrates critical plasma physics on schedule in the early 2030s, this would be a decisive intermediate step on the path to a commercial power plant in Gundremmingen.
