July 7 (Reuters) – Magnetic fusion start-up Proxima Fusion has raised €411 million ($469.69 million) from investors including Alphabet’s Google ​and German utility RWE as part ‌of a financing round, the Munich-based start-up said on Tuesday.

• “Proxima’s financing demonstrates that Europe can not only invent breakthrough technologies, but ‌also ​build globally competitive companies ⁠around them,” Francesco Sciortino, ⁠Proxima Fusion’s chief executive, said in a statement

• The round was led by XTX Ventures and East X ​Ventures, with RWE and Google as strategic investors, the company said

• It ⁠added that the ⁠financing round brings Proxima Fusion’s ​valuation to €2.4 billion ($2.7 billion)

• German utility company ​RWE invested €25 million euros in the funding ‌round

• RWE signed an agreement with Proxima to partner on building the first stellarator fusion power plant on ⁠the site of a former nuclear fission power plant in Gundremmingen, Bavaria

• Unlike the burning ⁠of fossil ‌fuels or the fission ⁠process of existing nuclear power ​plants, ‌nuclear fusion offers the possibility ​of abundant ⁠energy without pollution, radioactive waste or greenhouse gases, replicating with lasers or magnets the reaction that fuels the sun
