This Week’s Fusion News: July 31, 2026
July 31, 2026
This week the Max Planck Institute for Plasma Physics won €6 million to develop 2-megawatt gyrotrons for Wendelstein 7-X, the U.S. Department of Energy selected 278 Genesis Mission projects including commercial fusion, Oak Ridge National Laboratory and Rutherford Energy Ventures launched FULCRA to build shared fusion testbed infrastructure, and the Fusion Industry Association reported a record $4.48 billion raised across 56 companies in a single year. In The Fusion Report’s coverage, Commonwealth Fusion Systems raised another $1 billion to reach $4 billion in total capital and hired former Moderna CFO Lorence Kim; Thea Energy won a $20 million ARPA-E SCALEUP award for the first domestic modular HTS magnet line as national labs turned quantum supercomputing on the FLiBe salt behind tritium breeding; Barclays backed the UK Infinity Fusion Consortium as Inertia published a ten-goal Phase 1 commercialization roadmap; and Pacific Fusion and Lawrence Livermore pushed the Sirius impedance-matched Marx generator past 3,000 shots.

Where is Battery Energy Storage System Technology Going?
/ May 19, 2026
US grid-scale BESS capacity is now 45 GW, and California alone added 16.9 GW since 2018. Lithium-ion still leads, riding the EV cost curve, but sodium-ion, vanadium redox flow, and iron-air batteries each have a distinct play in stationary storage. Each technology fits a different point on the duration, safety, and cost curves.
Thea Energy operated its first full-scale stellarator shaping coil, and The Fusion Report dug into whether $50/MWh is really the bar for commercial fusion in the US. Fusion lands on China’s 15th Five-Year Plan as a frontier priority, ITER explains how fusion is pushing AI to evolve, Xcimer Energy keeps stacking senior hires, and Stellarex Energy and TAE Technologies both add new joint work with UKAEA.
Thea Energy Announces Successful Operation of Full-Scale Planar Shaping Coils
/ May 14, 2026
Thea Energy has successfully operated its first full-size, full-current, full-field stellarator planar shaping coil at over 6 T and 20 K, hitting Eos-spec performance. The milestone validates the company’s software-controlled magnet approach and its in-house build in Kearny, NJ, where a second facility is planned for 2026 to scale shaping coil production.
How Real is the Need To Hit $50 per Megawatt-Hour for Fusion Energy to Succeed In the US?
/ May 12, 2026
Bob Mumgaard, CEO of Commonwealth Fusion Systems, said fusion needs to hit $50/MWh to succeed. But US wholesale prices swing from $24 to $260/MWh by region, Europe and Japan run $95 to $100/MWh. AI data centers paying behind the meter face $150 to $300/MWh. $50/MWh is a goal, not a requirement. The real bar is facility Q>10.
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.
