About

Helion Energy is a fusion energy company working to develop the first commercially viable nuclear fusion power plant. Founded in 2013 and headquartered in Everett, Washington, Helion has pioneered a unique approach to fusion: instead of using deuterium-tritium (D-T) fuel like most fusion programs, Helion uses deuterium-helium-3 (D-He3) fuel with a proprietary field-reversed configuration (FRC) reactor design that simultaneously generates electricity directly through electromagnetic induction — potentially skipping the turbine step that adds complexity to other fusion approaches.

About

Zephyr Fusion is an early-stage nuclear fusion company targeting the decarbonization of industrial heat — the process heat used in steel mills, cement plants, chemical facilities, and other heavy industries that collectively account for approximately 20% of global CO2 emissions. While most fusion programs target electricity generation, Zephyr's approach focuses on delivering high-temperature heat (>1000°C) directly to industrial processes, potentially displacing fossil fuel combustion in applications where electrification is difficult or impossible. The company is developing a compact fusion device designed for co-location with industrial facilities.
