Type One Energy, Tokamak Energy and Construction Giant AECOM Form the UK Infinity Fusion Consortium
/ May 7, 2026
Type One Energy, Tokamak Energy, and AECOM have formed the UK Infinity Fusion Consortium, a private-sector-led effort to build a 400 MWe stellarator-based fusion power plant in the United Kingdom by 2034. The plant is the second to use Type One Energy’s stellarator design and the second fusion plant announced for the UK, after the STEP tokamak.
Zap Energy is becoming an integrated nuclear platform, pairing its sheared-flow-stabilized Z-pinch fusion machine with a 10 to 15 MW sodium-cooled microreactor on the fission side. The company also named Zabrina Johal as CEO. The Fusion Report sat down with Zap’s Ryan Umstattd to unpack the strategy, the funding picture, and the technology overlap.
This week’s fusion briefing covers Zap Energy’s new CEO and pivot to integrated fission-fusion, Commonwealth Fusion’s first-ever PJM interconnection filing, a joint CEO letter pressing Brussels for a coordinated fusion strategy, a new commentary on the $50/MWh cost bar, and nT-Tao’s MoU with Israel’s national water company to explore fusion-powered desalination.
The Fusion Decathlon Part 5: Who Are the Winners? Actually, No One Yet…
/ April 30, 2026
In the finale of The Fusion Report’s Decathlon series, we hand out the medals. Sort of. Events 8 (funding) and 9 (regulation) are essentially complete. Events 1 and 2 (plasma performance and drivers) sit at the halfway mark, with KSTAR, EAST, JET, Polaris, and SPARC closing in. Events 3 through 6 are barely underway. No clear winner yet.
The Shot Clock to Put Electricity on the Grid: Inside Fusion 2035 on May 7
/ April 29, 2026
On Wednesday, May 7, The Fusion Report hosts Fusion 2035: The 9-Year Shot Clock, a half-day webcast bringing seven companies onto one stage to pressure-test the mid-2030s commercial timeline. Inertia, TAE Technologies, Thea Energy, Type One Energy, Realta Fusion, Peak Nano, and E&P Technologies each take 20 minutes, followed by a 45-minute live panel moderated by Mike Heumann of Ignition Research.
Helical Fusion Closes Series B Round, Launches Helix Program Official Partners
/ April 28, 2026
Japan’s Helical Fusion closed its Series B at JPY 2.7 billion ($17M US), bringing total funding to roughly JPY 9.8 billion ($61.4M US). The company also launched the Helix Program Official Partners with three founding industrial collaborators: NICHIAS, Hasetora Spinning, and Seno Kisen. Manufacturing for the Helix HARUKA demonstration magnets is now underway.
Commonwealth Fusion Systems CEO Bob Mumgaard pegged SPARC’s turn-on to 2027 and teed up construction of the company’s 400 MW Virginia commercial plant to begin immediately after, in a Reuters NEXT interview. The UK Atomic Energy Authority took a strategic position in First Light Fusion’s £25 million first close, and General Fusion scheduled its April 29 Analyst Day at the Nasdaq MarketSite as its proposed $1 billion SVAC combination nears close. Peak Nano and E&P Technologies co-authored a piece on how impedance-matched generators are reshaping the capacitor stack behind inertial confinement fusion.
The Fusion Decathlon Part 4: More Magnetic Fusion Energy (MFE) Solutions
/ April 23, 2026
Part 4 of The Fusion Report’s Decathlon series covers three more magnetic confinement approaches. Z-pinch machines run massive currents through plasma. Field-reversed configurations form self-stabilizing plasma rings. Magnetic mirrors trap plasma in open-ended bottles. Meet the companies betting on each: Zap Energy, Helion, TAE Technologies, Realta Fusion and more.
