Google joined a €411 million (US$468 million) Series C funding round in Munich-based Proxima Fusion, backing the startup’s commercial tokamak reactor development. The capital will underwrite prototype scaling and plasma confinement refinement, integrating long-term fusion power ambitions into Google’s broader clean energy strategy.
Proxima Fusion closed a €411 million (US$468 million) Series C financing on July 7, with Google participating alongside a consortium of technology and energy investors. This infusion will fund prototype reactor builds and expansion of the company’s European pilot facilities.
The Munich-based startup focuses on compact tokamak designs aimed at achieving net-positive fusion output by the late 2020s. Raised funds will accelerate work on plasma confinement, superconducting magnets and modular module testing.
By investing in fusion R&D, Google signals a push beyond renewables toward next-generation energy sources that could reduce long-term power procurement costs. Shareholders may view the move as a strategic diversification that strengthens Google’s ESG profile and future cost savings potential.
