FUSION ENERGY NEWS

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.

Barclays has announced it is supporting the UK Infinity Fusion Consortium, a private, sector-led collaboration formed in May 2026 by Type One Energy, Tokamak Energy, and AECOM to advance a commercial fusion power plant in the UK. The move puts one of Europe’s top five banks, with total assets of £1.54T, behind commercial fusion deployment and complements the UK Government’s Fusion Strategy and STEP program. Alongside the Barclays news, Inertia published its Phase 1 commercialization roadmap. Inertia’s ten Phase 1 goals include scaling target yield to more than 25x, which the company says is enough for a plant to deliver 250MW to the grid, and cutting high-power laser diode costs by roughly 50x. The Fusion Report weighs what a reliable capital source and a concrete engineering roadmap mean for the path to commercial fusion.

Pacific Fusion and Lawrence Livermore National Laboratory announced that Sirius, an impedance-matched Marx generator prototype designed and built at LLNL, has surpassed 3,000 shots under a Cooperative Research and Development Agreement. In the campaign, each pulse of the four-stage prototype delivered 60 gigawatts to a resistive load in a 100-nanosecond pulse at 95% energy efficiency, with the effort focused on component lifetime and reliability. The companies frame the result as evidence that technology developed at a national laboratory can be validated through repeated testing and scaled quickly by industry. Pacific Fusion says it has used the data to build a June prototype that reached roughly 440 GW of peak output power and about 1.1 MV in 80 nanoseconds, and it plans to break ground later this summer on its Demonstration System in Albuquerque, New Mexico. The Fusion Report weighs the milestone against the roughly 31.5 million shots a production pulser would need to run for a year, and the tritium and neutron challenges that remain.

This week Pacific Fusion and Lawrence Livermore National Laboratory reported that the Sirius pulsed power prototype has surpassed 3,000 shots, validating the impedance-matched Marx generator architecture that Pacific Fusion has already scaled into a system delivering the highest peak power ever from a single-step pulsed power driver. Inertia Enterprises opened its new Livermore headquarters, a 50,000 square foot facility housing the world’s first fusion fuel target factory. Oak Ridge National Laboratory, Cleveland Clinic, and IBM completed the first known quantum computations of fusion fuel materials, modeling nine configurations of the tritium breeding salt FLiBe. And General Fusion became the first publicly listed fusion company as GFUZ began trading on the Nasdaq with roughly $150 million in cash. Plus The Fusion Report’s mid-year 2026 funding status and Realta Fusion selects Madison, Wisconsin for its new headquarters and The Realta Forge R&D facility backed by up to $55 million in state and city incentives.

The Fusion Report’s mid-year 2026 funding status finds total lifetime private funding for commercial fusion at $11.52B as of June 30, 2026, up roughly $2.4B from June 2025. Four companies now top $1B in lifetime funding: Commonwealth Fusion Systems ($2.923B), Helion Energy ($1.502B), TAE ($1.321B), and Shine Fusion ($1.040B). Major rounds in the period include CFS at $863M, Helion at $465M, Inertia at $450M, and $240M each for Shine Fusion and Focused Energy. Nuclear fission and SMR startups raised roughly $2B in the same window, while AI captured 70% of global VC funding in Q2 2026 alone. In a July postscript, Proxima Fusion raised €411M ($468M US) in new funding and General Fusion went public on the NASDAQ, lifting industry lifetime funding to $12.18B.
