Proxima Fusion, based in Munich, Germany, announced the completion of a €411 million ($468 million) funding round, with participation from technology giant Google and energy company RWE.This funding, disclosed on July 7, was led by XTX Ventures and East X Ventures, elevating Proxima’s valuation to €2.4 billion ($2.7 billion) and marking it as the best-financed fusion company in Europe.Founded in April 2023 as a spin-off from the Max Planck Institute for Plasma Physics, Proxima Fusion is focused on developing Quasi-Isodynamic (QI) stellarators, a type of magnetic confinement reactor.RWE’s investment of €25 million ($28.6 million) follows a partnership agreement to establish a stellarator fusion power plant at a former nuclear fission site in Gundremmingen, Bavaria.Dr. Markus Krebber, CEO of RWE AG, emphasized the potential for Germany to become a leader in nuclear fusion, urging federal and state governments to create favorable conditions for commercial reactor development.Proxima’s funding will facilitate the construction of its net-energy stellarator demonstrator, named Alpha, near Munich, in collaboration with the state of Bavaria and the Max Planck Institute.Dr. Francesco Sciortino, co-founder and CEO of Proxima Fusion, noted that Europe is competing with the U.S. and China to establish the first fusion power plant. He stated that the financing reflects investors’ recognition of the urgency and opportunity in developing this generational energy technology.Since its inception, Proxima has secured over €650 million ($740 million), including €95 million ($108 million) in public grants. The latest funding surpasses its target to match Bavaria’s commitment of €400 million ($457 million) in public funding.The company plans to focus on completing the Stellarator Model Coil, expanding high-temperature superconducting cable production, and enhancing engineering and manufacturing systems for stellarators. Proxima also intends to hire additional staff across engineering, manufacturing, and operations to expedite progress.Proxima aims to complete Alpha by the early 2030s, which will support the development of its first commercial stellarator fusion power plant, Stellaris, later in the decade.Google’s investment aligns with its broader strategy to explore fusion and nuclear energy as sustainable power sources for its data centers and AI infrastructure, amidst challenges in achieving carbon-free energy goals due to the rapid growth of its AI operations.Other investors in this funding round include KfW Capital, SPRIND, and Burda Principal Investments, with returning investors such as Plural, UVC Partners, and Balderton.
