We do not usually get to speak twice in the same week about the same company. Yet, here we are, talking about Proxima Fusion, again, the company that claims to be Europe’s best-funded fusion company.
After securing more than €650 million ($740 million) in cumulative funding, including €95 million in public grants, the developer of next-generation stellarators for commercial fusion energy signed a Memorandum of Understanding (MoU) with Freemelt, a manufacturer and supplier of Electron Beam Powder Bed Fusion (E-PBF) 3D printers.
Through the agreement, Freemelt becomes a member of the Alpha Alliance, a collaboration between industrial companies and research institutes working on the development of Alpha, a stellarator-based fusion demonstrator.
“Fusion is a strategic focus area for Freemelt, and we are pleased to join the Alpha Alliance together with Proxima Fusion and the other partners. This collaboration further validates Freemelt’s position within the fusion ecosystem and provides an opportunity to contribute our expertise in tungsten manufacturing to one of Europe’s most ambitious fusion programmes,” says Daniel Gidlund, CEO of Freemelt.
Alpha’s development pathway
Proxima Fusion focuses on developing stellarator technology for safe, sustainable and cost-effective fusion energy. The company’s Alpha programme aims to demonstrate net energy production in a stellarator capable of steady-state operation. This would represent an important step towards commercial fusion power.
The partners expect the collaboration to progress through successive development phases: design studies, prototyping, testing and future industrialization activities. The MoU provides a framework for cooperation, and the parties intend to establish specific agreements for future projects and deliveries.
“We are pleased to welcome Freemelt to the Alpha Alliance. Freemelt’s expertise in additive manufacturing and tungsten components will be an important contribution to the development of Alpha and our shared ambition to accelerate the path towards commercial fusion energy,” says Lucio Milanese, co-founder and Chief External Affairs Officer at Proxima Fusion.
