The company is currently operating its Lawson Machine 26, which reached a temperature of approximately 8.4 million degrees Celsius.
Germany's University of Rostock and Helmholtz-Zentrum Dresden-Rossendorf have launched the High Energy Density Initiative (HEDI), a research hub focused on studying matter under extreme conditions relevant to nuclear fusion. The initiative includes establishing a new Institute of High-Energy-Density Physics and involves international collaborations and funding from the German government and regional states.
General Fusion and Renexia announced a framework agreement to collaborate on the commercial deployment of fusion energy technology in Italy, including potential siting, development, and construction of fusion power plants.
The Fusion Industry Association's 2026 report states that supply chain spending in the nuclear fusion sector increased by 24% in 2025, but targeted incentives are needed to support capacity building in the next decade.
The Fusion Industry Association reported that fusion supply chain spending increased by 25% to USD 538 million in 2025, with ongoing concerns about access to specialist materials and fuel systems.
General Fusion has achieved plasma heating to approximately 8.4 million degrees Celsius (0.72 keV) using its LM26 Magnetized Target Fusion machine, marking progress toward its technical milestones. The results are submitted for peer review and demonstrate significant plasma compression and heating during the experiment.
General Fusion's LM26 machine demonstrated compressional heating of a deuterium plasma during experiments, resulting in more than a three-fold increase in electron temperature and a ten-fold increase in density across 11 compression shots.
Lancaster University in England has introduced a nuclear operations simulator capable of modeling both fusion and fission reactors, with software developed by Tokamak Energy, GSE Solutions, Westinghouse, and Norway’s Institute for Energy Technology. The simulator will be available for use in the fall 2026 semester for educational purposes.
ITER's welding engineers are developing procedures and strategies for welding components of the tokamak, addressing challenges such as accessibility, shrinkage, and space constraints, with the goal of defining standards that may influence future fusion projects.
Oxford Sigma joined the Steering Committee for the MatDB4Fusion platform, a global database for fusion materials data supported by CATF and OECD-NEA, to help guide its development and governance.
Xie Huasheng, a fusion theorist and plasma simulation scientist, founded VeloAlpha to develop FusionAlpha, a simulator that uses artificial intelligence to improve the accuracy and efficiency of fusion reactor design testing on computers.
Germany has launched a multimillion-dollar fusion research hub called the High Energy Density Initiative (HEDI), involving the University of Rostock and Helmholtz-Zentrum Dresden-Rossendorf, to study matter under extreme conditions similar to those inside stars and planets.
The central magnet bundle for the NSTX-U spherical tokamak at Princeton Plasma Physics Laboratory was delivered to the facility in New Jersey and is being prepared for installation, with experiments expected to begin in 2027.
