Helion Energy
Helion Energy, Inc. is an American fusion research company located in Everett, Washington. It is developing a magneto-inertial fusion technology to produce fusion power and helium-3 via aneutronic fusion, which, if successful, would produce low-cost clean electric energy using a fuel that can be derived exclusively from water.
The company was founded in 2013 by David Kirtley, John Slough, Chris Pihl, and George Votroubek. The management team won the 2013 National Cleantech Open Energy Generation competition and awards at the 2014 ARPA-E Future Energy Startup competition, were members of the 2014 Y Combinator program, and were awarded a 2015 ARPA-E ALPHA contract, "Staged Magnetic Compression of FRC Targets to Fusion Conditions".
Helion was one of five finalists for the 2022 GeekWire Awards for innovation of the year. It was one of five finalists for the 2023 GeekWire Best workplaces of the year.
On May 10, 2023, Helion Energy announced that it had agreed to provide 50 MWe to Microsoft starting in 2028. This is the first commercial agreement for fusion energy. Commentators are skeptical.
In October 2023, Helion and Nucor Corporation, the largest steel producer and recycler in North America, agreed to develop a 500-MWe fusion power plant at one of Nucor's manufacturing facilities. Their target for beginning operations is 2030.
Helion was a finalist for the 2025 GeekWire Awards in the category of Sustainable Innovation of the Year.
Helion's approach uses a linear fusion system with pulsed magnetic compression and differs from the traditional design for fusion reactions, which relies on tokamaks.
The system is intended to operate at 1 Hz, injecting plasma, compressing it to fusion conditions, expanding it, and recovering the energy to produce electricity. The pulsed-fusion system used is said to be theoretically capable of running 24/7 for electricity production. Due to its compact size, the systems would be able to replace current fossil fuel infrastructure without major needs for investment.
