During his State of the State address on February 17, Wisconsin Gov. Tony Evers announced the launch of a new nuclear siting study that will be undertaken by a partnership between the Public Service Commission (PSC) of Wisconsin and the Department of Nuclear Engineering and Engineering Physics at the University of Wisconsin–Madison.

Two start-ups working to commercialize fusion energy made headlines last week. Helion Energy announced that its Polaris prototype fusion energy machine recently demonstrated measurable deuterium-tritium fusion and achieved a plasma temperature of 150 million degrees Celsius (MºC). Newcomer Inertia Enterprises announced that it has raised $450 million in its Series A fundraising round.

The Department of Energy’s newly published Genesis Mission National Science and Technology Challenges describes 26 challenges and corresponding AI solutions designed to advance the artificial intelligence–focused Genesis Mission, which was established by presidential executive order last November to develop an “integrated platform that connects the world’s supercomputers, experimental facilities, AI systems, and unique datasets across every major scientific domain to double the productivity and impact of American research and innovation within a decade.”

California-based Pacific Fusion, in partnership with Sandia National Laboratories, has reported “removing a significant roadblock to practical fusion power at scale” by achieving pulser-driven inertial confinement fusion (ICF) with a simpler, less expensive approach than previously used.

Lawrence Livermore National Laboratory has designed a model to help assess the economic impact of future fusion power plant operations—specifically, the operation of inertial fusion energy (IFE) power plants. Further, it has made its Generalized Economics Model (GEM) for Fusion Technology—an Excel spreadsheet—available for download.

Many people are familiar with Godzilla as a giant reptilian monster that emerged from the sea off the coast of Japan, the product of radioactive contamination. These days, there is a new Godzilla, but it has a positive—and entirely fact-based—association with nuclear energy. This one has emerged inside the Tokamak Assembly Preparation Building of ITER in southern France.

Commonwealth Fusion Systems makes no small plans. The company wants to build a 400-MWe magnetic confinement fusion power plant called ARC near Richmond, Va., and begin operating it in the early 2030s. And the plans don’t end there. CFS wants to deploy “thousands” of fusion power plants capable of accelerating a global energy transition.

Oak Ridge National Laboratory has announced a partnership with Japan’s Kyoto Fusioneering to develop technology for speeding the deployment of commercial fusion energy through the creation of a breeding blanket test facility. The lab said that the partnership will “leverage ORNL’s expertise in supercomputing, advanced manufacturing, materials science, and fusion research, and complement KF’s UNITY test facilities.”

Princeton Plasma Physics Laboratory is leading a new initiative with the goal of using AI technology to accelerate the development of fusion energy research through high-fidelity computer simulations. The project includes national laboratories, universities, technology companies, and other partners.

Simulation, Technology, and Experiment Leveraging Learning-Accelerated Research enabled by AI (STELLAR-AI) has been developed as part of the Department of Energy’s Genesis Mission, which was established by presidential executive order last year to speed up the application of AI in scientific research.

General Fusion has entered into a definitive business combination agreement with Spring Valley Acquisition Corp. (SVAC) that would make General Fusion the first publicly traded pure-play fusion firm, the company announced on January 22. The business combination is projected to be completed in mid-2026.

Commonwealth Fusion Systems, a fusion firm headquartered in Devens, Mass., is collaborating with California-based computing infrastructure company NVIDIA and Germany-based technology conglomerate Siemens to develop a digital twin of its SPARC fusion machine. The cooperative work among the companies will focus on applying artificial intelligence and data- and project-management tools as the SPARC digital twin is developed.

Trump Media & Technology Group, the American media and technology company majority owned by President Trump, and California-based fusion company TAE Technologies, announced on Thursday the signing of a definitive merger agreement to combine in an all-stock transaction valued at more than $6 billion.

Fusion technology company Thea Energy announced this week that it has completed the preconceptual design of its fusion power plant, called Helios. According to the company, Helios is “the first stellarator fusion power plant architecture that is realistic to build and operate with hardware that is available today, and that is tolerant to the rigors of manufacturing, construction, long-term operation, and maintenance of a commercial device.”

Cornyn

Padilla

Sens. Alex Padilla (D., Calif.) and John Cornyn (R., Texas) have introduced bipartisan legislation to formally establish the Office of Fusion at the Department of Energy. This move seeks to codify one of the many changes put forward by the recent internal reorganization plan for offices at the DOE.

Companion legislation has been introduced in the House of Representatives by Reps. Don Beyer (D., Va.) and Jay Obernolte (R., Calif.), who are cochairs of the House Fusion Energy Caucus.

Details: According to Obernolte, “Congress must provide clear direction and a coordinated federal strategy to move fusion from the lab to the grid, and this legislation does exactly that.”

A new report from the F4E Fusion Observatory highlights the robust growth of investments in private companies that are developing fusion energy technologies. The report, Global Investment in the Private Fusion Sector, is an updated release of a previous F4E Fusion Observatory report, published “in response to the unprecedented acceleration of investments in fusion companies since June 2025, which are consolidating fusion as a fast-growing emerging market.”

Global funding: According to the report, the cumulative global funding in private fusion companies between June and September 2025 increased from €9.9 billion to €13 billion (about $11.6 billion to $15.17 billion). Funding for the private fusion sector in September was more than eight times greater than in 2020. The report also identifies 77 companies that are in the “fusion private ecosystem.”

Fusion energy for commercial use is a technology that is yet to be realized, but one company is already setting its sights on taking it from land to sea.

The University of California, through its Initiative for Fusion Energy, has awarded $8 million in multicampus research grants, in partnership with UC-managed national laboratories, to fund research aimed at accelerating progress toward fusion energy.

Canada’s Fusion Fuel Cycles Inc. (FFC), a joint venture between Canadian Nuclear Laboratories and Japan’s Kyoto Fusioneering, announced that it has officially entered the construction phase of its flagship project, the Unique Integrated Testing Facility (UNITY-2), at CNL’s Chalk River Laboratories in Ontario.

In the report Fusion Forward: Powering America’s Future issued earlier this month by the Special Competitive Studies Project’s (SCSP) Commission on the Scaling of Fusion Energy, it warns that the United States is on the verge of losing the fusion power race to China.

Noting that China has invested at least $6.5 billion in its fusion enterprise since 2023, almost three times the funding received by the U.S. Department of Energy’s fusion program over the same period, the commission report urges the U.S. government to prioritize the rapid commercialization of fusion energy to secure U.S. national security and restore American energy leadership.

SCSP is a nonpartisan, nonprofit initiative making recommendations to strengthen America’s long-term competitiveness in emerging technologies. Launched in fall 2024, the 13-member commission is led by Sens. Maria Cantwell (D., Wash.) and Jim Risch (R., Idaho), along with SCSP president and commission co-chair Ylli Bajraktari.

Helical Fusion, a Japan-based fusion start-up that is developing a stellarator fusion power reactor, has announced it has successfully demonstrated its high-temperature superconducting (HTS) coil under relevant magnetic conditions.
