The work included advancing manufacturing processes and producing trial batches of materials such as palladium-based compounds.
General Fusion and General Atomics announced a collaboration to develop advanced diagnostic systems for the LM26 fusion demonstration program, aiming to measure plasma temperatures up to and exceeding 10 keV (100 million degrees Celsius).
Since 2024, the ITER Organization has held three public-private fusion workshops focusing on technological barriers, breakthroughs, and the importance of partnerships to accelerate the development of commercial fusion energy. The latest workshop, held from April 27 to 30, 2026, in southern France, gathered nearly 300 participants to discuss innovation, project management, and collaboration efforts.
Tokamak Energy was confirmed as the Magnet Systems Partner for the UK's STEP Fusion programme, receiving a £70 million contract to deliver magnet work packages up to March 2029. The company will provide high temperature superconducting magnet systems and support the development of fusion technology.
Oxford Sigma, in partnership with UKAEA and through the FORT programme, has developed a component qualification strategy for robotics used in fusion energy, engaging with UK supply chain companies to prepare for future qualification standards. The initiative addresses the lack of existing standards for qualifying robotics in fusion-like radiation environments.
Type One Energy announced progress toward commercial fusion energy, including publishing the first comprehensive physics basis for a stellarator fusion power plant, testing a 77K magnet at MIT, and partnering with the Tennessee Valley Authority to deploy America's first commercial stellarator fusion plant.
Oxford Sigma has launched two new research projects, STUBBI and SHyELD, funded by UKAEA and other partners, to develop high-performance fusion shielding materials using tungsten and metal hydrides. The projects aim to create scalable prototypes and validate their performance under fusion conditions.
Oxford Sigma, in collaboration with STEP Fusion, Rockwood Cryogenics, and Atled Engineering, demonstrated a new quench protection concept for superconducting magnets at the University of Strathclyde, which is a key development for the UK's STEP fusion program aiming to deliver a prototype fusion powerplant by 2040.
