Last October, Pacific Fusion emerged from stealth with a splashy $900M Series A and a commitment to build an inertial fusion machine based on the technologies that made the National Ignition Facility (NIF) and the Z Machine successful. Now, the company has come out with a roadmap to build a net gain facility by 2030—and […]
The time has finally come: Commonwealth Fusion Systems is assembling SPARC. The megafunded fusion company has been working on the components of its flagship tokamak for the last several years, and now it’s putting the pieces together. This week, the company announced the installation of the cryostat base in the SPARC facility—the first piece of […]
A young fusion firm in Sweden has closed a funding round in its quest to harness the power of the atom. Novatron Fusion is working toward building a stable and easily manufacturable fusion machine using magnetic confinement. Last week, it closed a €10M funding round to push it into the next stage of development: building […]
First Light Fusion is going through changes. Until recently, the fusion developer planned to build a fusion plant of its own, but a few weeks ago announced it would take a different tack. Instead of pursuing a commercial fusion machine, First Light will commercialize its amplifier technology to support the burgeoning fusion sector. “If the […]
Another batch of funding has hit the fusion sector, and this time around, it’s supporting a simplified version of the twistiest concept around. Renaissance Fusion, a French stellarator developer, announced last week that it’s raised a €32M ($34.7M) funding round to advance development of its fusion machine concept and work toward a demo plant (h/t […]
In a country where it’s tough to find broad bipartisan support for most anything, fusion energy has managed to buck the trend. At least, that’s how it sounded from the stage Wednesday afternoon at the Fusion Industry Association meeting, where the US House Fusion Energy Caucus co-chairs and vice chairs reassured the industry that they’re […]
The world needs more energy—we think we can all agree on that. That new energy ought to be clean, firm, and abundant. The fusion industry is rising to meet that challenge. Realta Fusion is tackling the problem via the magnetic mirror approach, which—like many fusion concepts—was explored back in the ‘70s before falling off the […]
No man is an island, and the same goes for commercial fusion developers. Turns out there’s no need to go it alone. This week, Type One Energy, an Oak Ridge, TN-based stellarator developer, announced that it secured an exclusive license from leading tokamak fusion company Commonwealth Fusion Systems (CFS). Type One will use the latter’s […]
We’ve got what you’ve all been waiting for, folks: the first fusion megaround of 2025. Helion announced this week that it has raised a $425M Series F round. The Washington-based fusion company, famously backed by OpenAI’s Sam Altman, is working to develop commercial fusion on a much shorter timeline than its competitors. Lightspeed Venture Partners […]
The past year has been a big one for the fusion sector. It was a huge year for fundraising, with more than $2B in investor dollars flowing into the sector, and for regulatory development, with US regulators making rules to ensure that fusion tech is ultimately treated differently than reactors on the other side of […]
