The Department of Energy has approved Xcimer Energy's Athena fusion power plant preconceptual technical design. With this milestone achieved, the Denver, Colo.-based company is now moving forward with its plans to develop economical laser inertial confinement fusion using two beamlines, gas laser technology, and a molten salt fusion chamber.

The National Ignition Facility at Lawrence Livermore National Laboratory demonstrated net energy gain from inertial confinement fusion in 2022 using solid-state glass lasers and 192 beamlines.

DOE’s latest fusion strategy aims for commercial energy by the 2030s

June 10, 2026, 1:20PMNuclear News

The Department of Energy has released what it is calling a “finalized” national strategy to accelerate the development and commercialization of fusion energy, with the goal of scaling up the private fusion sector by the mid-2030s.

Released on June 9, the Fusion Science and Technology (FS&T) Roadmap builds on an earlier road map document the DOE released in October 2025, which itself echoed plans issued by the DOE’s Office of Fusion Energy Sciences in 2023 and 2024.

According to the DOE, this finalized road map brings together fusion science, technology, infrastructure, workforce development, and commercialization priorities into a single national strategy, outlining how the DOE, industry, universities, and national laboratories will work together to accelerate the path toward U.S. commercial fusion energy.

Three companies have come together to form the U.K. Infinity Fusion Consortium with the objective of developing the first private sector–led fusion power plant in the United Kingdom using existing “commercially credible” technologies.

The consortium is expected to benefit from the combination of the three partners’ expertise. Tennessee-based fusion start-up Type One Energy brings its 400-MWe Infinity Two stellarator fusion power plant design. British fusion technology company Tokamak Energy has its HTS magnet technology and manufacturing background. Texas-based consulting firm AECOM has international engineering and infrastructure capabilities.

Researchers have developed a model to generate images that serve as synthetic data close-ups of tungsten surfaces under fusion reactor conditions.

Tungsten is a top-choice material for plasma-facing components (PFCs) in fusion machines, so understanding tungsten’s performance is critical to the safety and longevity of component designs.
