Munich-based fusion energy startup Marvel Fusion has raised an additional €50 million in its Series B funding round, bringing the total to €113 million. This development positions Marvel Fusion as the best-funded fusion energy company in Europe and marks a critical step toward realizing its ambitious plans to revolutionize clean energy.
The funding extension attracted major investors, including EQT Ventures, Siemens Energy Ventures, and the European Innovation Council (EIC) Fund, which is making its first-ever equity investment in fusion energy. Existing backers Tengelmann Ventures and Bayern Kapital also increased their stakes in the company.
Building the Future of Fusion Energy
Founded in 2019, Marvel Fusion is pioneering a laser-based nuclear fusion technology that aims to provide clean, safe, and sustainable energy. Using inertial confinement fusion, the company employs ultra-short pulse lasers to ignite fusion reactions within nano-structured fuel capsules. This innovative approach could pave the way for a new era of carbon-free power generation.
With the latest investment, Marvel Fusion is moving beyond research and development toward industrial deployment. The company is currently constructing a €139 million laser facility in collaboration with Colorado State University. It also plans to build a prototype fusion plant by 2032, with full commercial operations targeted for 2036.
Industry Partnerships Strengthen Fusion Efforts
Marvel Fusion has also deepened its collaboration with Siemens Energy, a leading global energy technology company. Together, they are developing the conceptual design of a fully integrated fusion power plant. Siemens Energy will contribute expertise in heat transfer and power generation systems, reinforcing the feasibility of laser-based fusion technology.
“We have long been involved with Marvel Fusion, and we look forward to continuing our joint efforts to bring fusion energy to reality,” said Juha Pankakoski, Executive Vice President Global Functions at Siemens Energy. “When that day arrives, Siemens Energy is committed to being at the forefront.”
Marvel Fusion is also ramping up efforts to scale laser production, a critical component in achieving commercially viable fusion energy. With two laser prototypes currently in development, the company is actively forging partnerships to advance high-energy laser systems that can meet the high-gain energy requirements for competitive electricity generation.
Strategic Investment Amid Global Energy Challenges
The investment comes at a time of growing geopolitical tensions and rising energy demands, pushing Europe to strengthen its energy sovereignty. The European Commission has underscored the strategic importance of fusion energy, stating that it is “no longer a research subject” but rather “an industrial challenge with immense potential for Europe’s industry, competitiveness, and strategic autonomy.”
Svetoslava Georgieva, Chair of the EIC Fund Board, highlighted the significance of the investment: “The European Innovation Council’s participation in Marvel Fusion demonstrates our commitment to high-impact innovation and fusion technology as a strategic priority for Europe’s future.”
Fusion energy, once commercialized, has the potential to transform the global energy landscape by providing a reliable, carbon-free power source. With its latest funding boost, Marvel Fusion is accelerating its mission to turn this vision into reality.
