The UK Infinity Fusion Consortium, comprising Type One Energy, Tokamak Energy, and AECOM, was announced to develop the UK's first private-sector fusion power plant, building on the US-based Infinity Two project with a target for commercial operation in 2034.
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.
At the ITER fusion project, experts discussed how artificial intelligence is being used to support construction, maintenance, simulation, and operations, especially given the challenges of scarce and complex data in fusion research.
The US Department of Energy is seeking nominations for the Associate Director of the Fusion Energy Sciences Program, and CFS is in the process of permitting its first commercial fusion plant, the Fall Line Fusion Power Station, in the US. Europe’s fourth Vacuum Vessel sector for ITER has been completed and shipped.
Japan is developing robotic tools for the initial assembly of ITER blanket components, including multifunctional end effectors for gripping, fastening, welding, and cutting, to be used starting in 2032. These tools will operate in a non-radiological environment and inform the development of remote handling systems for maintenance during ITER operation.
The first phase of feeder assembly at ITER, involving the connection of superconducting busbar joints in the Tokamak Building galleries, has been completed, with 50 joints successfully installed. The next phase will occur inside the tokamak pit, where tighter spatial and schedule constraints apply.
Type One Energy submitted its initial licensing application for a commercial fusion project at the TVA Bull Run Energy Complex in Tennessee, marking a regulatory breakthrough in the fusion sector and establishing a pathway for fusion power deployment under existing safety frameworks.
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.
Helion is developing new magnet conductor materials, including high-strength copper alloys and nanolaminate conductors produced via accumulative roll bonding, to create electromagnets capable of withstanding the forces in fusion machines while maintaining high electrical conductivity.
Oxford Sigma published a peer-reviewed paper titled "Qualification Pathways for Fusion Structural Materials" in the Journal of Nuclear Engineering, discussing frameworks for demonstrating material performance in fusion environments and the importance of qualification evidence for fusion system deployment.
Pacific Fusion opened its fusion facility to external users through its Pacific Fusion Users Program, allowing access to its Demonstration System for research and development. The company also published a framework for evaluating progress toward commercial fusion.
The UK government, with Lord Vallance, launched a new fusion strategy during a visit to Tokamak Energy, which includes over £2.5 billion in funding over five years to support fusion research and commercialization.
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.
EX-Fusion announced the start of a project to develop an inertial nuclear fusion module using a blue-violet semiconductor laser, led by founder and director Yoshitaka Mori, as part of Japan's Moonshot Goal 10 initiative.
STARTORUS FUSION completed a major upgrade of Tsinghua University's SUNIST device within three months as a turnkey project, redesigning and standardizing key subsystems to enhance research capabilities.
Helion's Polaris device achieved measurable D-T fusion, reaching plasma temperatures of 150 million degrees Celsius and producing neutron signals ten times higher than D-D fusion, confirming successful D-T fusion operation.
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.
