Helion

About

Founded in 2013, Helion is a private headquartered in Everett, United States with approximately 200-500 employees specializing in Hydrogen.

Helion Energy is developing a novel approach to nuclear fusion using field-reversed configuration (FRC) plasmas and magneto-inertial fusion. Unlike traditional fusion approaches, Helion's pulsed, non-ignition system directly recovers electricity through electromagnetic induction rather than heat-based steam turbines. The company uses deuterium and helium-3 as fuel, which minimizes neutron production and radioactive waste. Helion's sixth prototype, Trenta, achieved 100 million degrees Celsius (9 keV) plasma temperatures and completed 10,000 high-power pulses during a 16-month continuous operation. The company's seventh prototype, Polaris, achieved 150 million degrees Celsius and demonstrated measurable thermonuclear deuterium-tritium fusion. Helion has secured a power purchase agreement with Microsoft to deliver 50+ megawatts of fusion electricity starting in 2028 and is constructing what it claims will be the world's first commercial fusion power plant in Malaga, Washington.
