The Tennessee Valley Authority (TVA) and Type One Energy signed initial contracts for Project Infinity, a fusion power plant development, to supply the Tennessee Valley with clean energy by the mid-2030s. TVA will assist in manufacturing and construction for the fusion machines at its facilities.
Helion has begun initial construction of Orion, the world's first fusion power plant, in Malaga, Washington, with the goal of delivering at least 50 MW of carbon-free electricity to Microsoft, marking a milestone after over a decade of development.
The company announced the operation of a high-power laser experimental facility at Kyoto Katsura in January 2025, aimed at developing laser fusion technology and industrial laser processing applications.
Ignition Computing announced the first stable release of IMAS-ParaView, a software tool that enables visualization of IMAS data in ParaView, which is available under the LGPL-3.0 license and can be installed from PyPI.
Novatron Fusion Group (NFG) officially inaugurated NOVATRON 1 at the KTH Royal Institute of Technology in Stockholm, marking the first private, fully integrated fusion plasma system in the EU and a milestone for Nordic fusion energy development.
Novatron Fusion Group published a scientific paper in Nuclear Fusion describing a 'triple-force' magnetic mirror approach that could improve plasma confinement efficiency by up to 1000 times, potentially advancing mirror machine technology for fusion energy.
EX-Fusion announced it raised approximately 2.6 billion yen in a Series A funding round, including 2.3 billion yen in equity and 300 million yen in loans, bringing its total funding to 5.6 billion yen.
Novatron Fusion Group is developing advanced diagnostic systems in collaboration with UKAEA as part of the TauEB project to measure plasma confinement time in their fusion experiments, aiding performance verification and operational adjustments.
Pacific Fusion announced progress on its Demonstration System (DS), which is on track to achieve net facility gain — more fusion energy output than energy input — by 2030, with the system expected to be 100 times higher gain and 10 times less costly than the previous record holder, the National Ignition Facility.
HB11 Energy has signed an $8.2 million agreement with the University of Adelaide to develop a high-efficiency laser for fusion energy applications, aiming to demonstrate over 10 percent wall-plug efficiency and establish a national laser fusion facility in Adelaide.
