• €32M Series A funding will accelerate Renaissance Fusion’s nuclear fusion reactor development and High Temperature Superconductors (HTS) commercialization.
• Renaissance Fusion is pioneering simplified stellarator reactors and proprietary liquid metal wall technology to deliver compact, low-maintenance fusion energy.
• The company aims to commercialize HTS technology for energy, storage, and medical imaging—generating near-term revenue ahead of full reactor deployment in the 2030s.

Renaissance Fusion, Europe’s first magnetic confinement fusion startup, has raised €32 million ($33.2 million) in Series A funding to advance its nuclear fusion reactor and High Temperature Superconductors (HTS) technology. Crédit Mutuel Impact’s “Révolution Environnementale et Solidaire” fund led the round, with participation from Lowercarbon Capital.

CEO and CTO Francesco Volpe said the company is working to make fusion energy as commonplace as ice is today.

“I believe we are working on something similar: a world where fusion seems magic today but will be common in a very near future.”
Renaissance Fusion targets commercial fusion reactors in the 2030s to deliver abundant, low-cost, low-carbon electricity.

What’s Happening:

• Renaissance Fusion, founded in 2020 near Grenoble, is advancing three core technologies: simplified stellarators, proprietary liquid metal walls, and HTS.
• The funding will enable the company to:
  • Manufacture and commercialize HTS.
  • Develop a reduced-scale stellarator reactor module.
  • Refine liquid metal wall technology, critical for shielding, tritium breeding, and efficient heat extraction.

Deputy Director Philippe Magaud of the CEA Institute for Magnetic Fusion Research emphasized the partnership’s strategic importance:

“Renaissance Fusion is one of two fusion companies, and the only one in magnetic fusion, selected by France 2030. It has a first-mover advantage in the European Union.“

Why It Matters:

• HTS commercialization: Renaissance Fusion’s wide, engraved HTS magnets generate strong magnetic fields, enabling smaller, simpler, and cheaper reactors.
• Liquid metals: These shield the reactor, breed fuel (tritium), and extract heat for electricity generation. Renaissance Fusion is the only magnetic fusion company advancing this tech.
• Simplified stellarators: The design allows for steady-state operation with lower complexity and maintenance.

Sabine Schimel, Managing Director at Crédit Mutuel Impact, underscored the potential:

“Once commercialized, nuclear fusion will have a huge environmental and economic impact. We are proud to contribute to the growth of this industry, which requires massive investment.”

What’s Next:

• Renaissance Fusion aims to generate near-term revenues by selling HTS, crucial for disrupting energy generation, transmission, storage, and medical imaging.
• The company plans to scale its technology partnerships, including an active collaboration with CEA, backed by a €10M “Innovative Nuclear Reactor” grant from BPI France.

Co-founder Martin Kupp summed up the company’s momentum:

“This funding round will help us achieve major milestones on our way to build our compact, low-maintenance stellarators.”

Bottom Line:

Renaissance Fusion is positioning itself as a leader in next-gen nuclear fusion and HTS production. Its simplified stellarator technology and HTS commercialization strategy are accelerating the path toward clean, scalable energy solutions with global impact.
