FUSION ENERGY NEWS

Realta Fusion announced it will build its corporate headquarters and fusion R&D facility, “The Realta Forge,” at OM Station, the former Oscar Mayer plant in Madison, Wisconsin. The state and city committed up to $55 million in incentives: an estimated $37.5 million in state sales and use tax exemptions, up to $15 million in WEDC enterprise zone tax credits, and $2.8 million in city tax increment financing. Realta expects to create over 600 jobs and to break ground before the end of the year on the facility where it will build Hammir, its prototype magnetic mirror fusion machine. The deal follows Wisconsin Act 165, the first standalone state law in American history to exempt fusion energy capital expenditures from state sales tax. The Fusion Report looks at why the hometown choice makes sense and what it signals about Realta’s next funding round.

Proxima Fusion raised 411 million euros ($468 million) led by XTX Ventures and East X Ventures with Google and RWE as strategic investors, a 2.4 billion euro valuation that makes it Europe’s best funded fusion company. Spring Valley and General Fusion shareholders approved the merger that lists General Fusion on Nasdaq as GFUZ, the first publicly traded pure play fusion company. UKAEA and Eni launched RH3OVA, a joint venture selling consultancy and operational services to the global fusion industry. And China completed final tests on the world’s largest superconducting fusion magnet, a 582 ton coil built entirely with domestic supply chains. Plus Helical Fusion signs a construction MoU for Helix KANATA, and Cosylab CEO Mark Plesko on why control systems are the missing backbone of commercial fusion.

Helical Fusion has added a long-established Japanese general contractor to its Helix Program as an Official Partner and signed a memorandum of understanding to collaborate toward the construction of Helix KANATA, the company’s fusion pilot plant targeted for the 2030s. The two firms will examine construction requirements and project execution approaches for future fusion power facilities. The contractor joins the earlier Official Partners announced in April 2026 in building out the industrial foundation for commercial fusion in Japan.

The Fusion Industry Association’s fourth annual supply chain report found fusion supply chain spending rose 24 percent in 2025 to $538 million, launched at the industry’s first supply chain trade show in Santa Fe. General Fusion signed a framework agreement with Italy’s Renexia to site and build commercial Magnetized Target Fusion plants. nT-Tao’s Q2 update logged more than 1,000 experiments and launched a fusion power barge project with ABS and Siemens Energy. LLNL found that circularly polarized lasers could save optics at NIF. The Fusion Report also covers CFS becoming the first international partner in the UKAEA’s £220 million LIBRTI tritium program and Realta’s first-ever direct conversion of plasma energy into electricity by a private fusion company. Plus the tracker at 24 companies and $11.4B in disclosed funding.

Commonwealth Fusion Systems has become the first international partner in the UK Atomic Energy Authority’s LIBRTI program, a £220 million effort to demonstrate net tritium production for fusion power plants. The two organizations will jointly design the experimental setup and run investigations at a new facility being built at UKAEA’s Culham Campus, which will draw on a high-flux neutron source from Shine Technologies. CFS, which describes itself as the best-funded fusion company with more than $3 billion raised, will build the test articles used to validate the tritium breeding blanket design for its ARC power plant planned for Virginia. Tritium breeding blankets are a shared engineering challenge across fusion approaches, and cross-company collaboration on the technology is becoming more common as the industry moves toward first-of-a-kind machines.

Realta Fusion demonstrated direct energy conversion (DEC) of plasma kinetic energy into electricity at the WHAM fusion machine at UW-Madison, drawing current at about 100 volts to light several bulbs. The company describes it as the first such demonstration by a commercial fusion company and points to DEC as a way to raise efficiency and lower cost in its planned mid-2030s plants.
