FUSION ENERGY NEWS

The first wall is the innermost boundary facing a fusion plasma, and no material yet does everything asked of it. Tungsten leads on heat handling but can embrittle under neutron damage, while steels, vanadium alloys, silicon-carbide composites, and ultra-high-temperature ceramics each trade one strength for another. A newer approach abandons the solid surface entirely in favor of flowing liquid metal. ITER has switched from beryllium to tungsten in its revised baseline, European suppliers have opened series-production lines, and Germany’s DINERWA project is developing next-generation alloys for high-heat-flux testing. Yet no fusion first wall has established a commercial operating record, and that gap, between industrialization and a bankable power plant, is where the real question sits.

MIT prices out fusion profitability, Fuse posts a record neutron yield, and Germany funds three fusion hubs. Plus EVs and the real US case for fusion.

The Fusion Report examines what will actually drive US demand for commercial fusion energy when it is expected to start coming online in the mid-2030s. The author argues that counting on AI is a mistake: most optimistic forecasts show electricity demand growth from AI starting to level off in the mid- to late-2030s, and the IEA cites a headwinds case in which data-center energy demand plateaus beyond 2030, reaching about 700 TWh by 2035. Nearer-term answers for decarbonizing electricity already exist, including solar plus battery storage, which the US EIA’s conservative baseline projects will account for at least 14% of total US electricity by 2035, and advanced nuclear fission. The author suggests stronger framing for fusion’s US case: roughly 100 GW of generation capacity is projected to retire by 2035, including 40% of the remaining US coal power plants, and if US EV adoption reached 50%, charging would increase total annual electricity consumption by roughly 13%-15% (500 TWh-600 TWh). The conclusion: fusion’s business strategy needs to start focusing on real opportunities instead of illusory ones.

This week TAE Technologies signed a strategic helium-3 supply and commercialization agreement with Black Moon Energy, a lunar-development company planning a robotic delineation mission to de-risk commercial-scale helium-3 production as TAE prepares to site its 50 MWe Da Vinci power plant. China’s Institute of Plasma Physics completed testing of the largest fusion magnet ever built, a 582-ton toroidal field coil destined for its BEST tokamak. UKAEA’s MAST Upgrade completed its most ambitious experimental campaign yet, producing more than 1,100 plasmas and achieving record plasma pressure while suppressing the edge instabilities that threaten commercial fusion machines. Oak Ridge National Laboratory licensed four cryogenic pellet fueling inventions to stellarator developer Type One Energy. And UC Santa Barbara teamed with Lawrence Livermore to accelerate plasma simulations with AI. Plus The Fusion Report examines the AI-driven DRAM shortage and what Andy Burnham becoming UK Prime Minister means for the UK’s $3.3B fusion program.

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.
