- Avalanche Energy has secured $29 million in funding to scale its compact fusion technology and expand its FusionWERX commercial test facility.
- The investment strengthens its path toward demonstrating net-energy fusion and deploying modular fusion systems for real-world applications.
Avalanche Energy has secured $29 million in fresh funding to accelerate the commercial development of its compact fusion technology.
RA Capital Management led the funding round. Meanwhile, existing investors Congruent Ventures, Founders Fund, Lowercarbon Capital, and Toyota Ventures all participated fully. In addition, new investors including 8090 Industries and Overlay Capital joined the round.
The funding unlocks a matched $10 million Washington State Department of Commerce Green Jobs Grant awarded in mid-2025. As a result, Avalanche now has the financial runway to scale operations and advance its fusion engineering programmes.
A significant portion of the capital will expand FusionWERX, Avalanche’s commercial-scale fusion test facility in Richland. The company launched the facility in April 2025. Notably, FusionWERX serves the emerging fusion ecosystem by supporting technology testing, workforce development, and component validation.
By 2027, the facility is expected to operate under a broad radioactive materials licence with advanced tritium-handling capabilities. Once fully operational, the site will support materials research, fusion component testing, and Avalanche’s Q>1 deuterium-tritium test programme. Ultimately, the programme aims to demonstrate the world’s first net-energy compact fusion system.
Beyond infrastructure, Avalanche plans to expand its workforce and procure long-lead equipment such as superconducting magnets. At the same time, the company will accelerate development of next-generation devices for material irradiation, mobile power generation, and grid support.
Founded in 2018 by Robin Langtry and Brian Riordan, Avalanche designs compact fusion systems for environments where conventional power solutions struggle. For example, the company targets applications in defence, space, remote installations, and grid-constrained regions. In addition, its modular fusion units support potential uses in space propulsion, underwater unmanned vehicles, data centres, and military facilities.
The company continues to report technical progress. In 2025, the team achieved a major high-voltage vacuum breakthrough by operating a fusion machine at 300 kilovolts. Consequently, the result enabled record electric field strength and improved magneto-electrostatic fusion efficiency.
Avalanche has also published three peer-reviewed papers on its Orbitron plasma confinement concept. Furthermore, the company plans to release additional research findings in 2026. These developments support Avalanche’s rapid engineering model, where design cycles occur in days rather than years.
Chief Executive Officer Robin Langtry said recent plasma physics breakthroughs have accelerated development momentum. He added that the new funding will support licensing for commercial fusion operations and preparation for the company’s Q>1 fusion test programme.
Investors say Avalanche stands out because it focuses on commercial deployment alongside research development. Therefore, they believe the company could help move fusion technology from laboratory research into real-world industrial and energy applications.
