Zap Energy vs Helion Energy
Side-by-side comparison of AI visibility scores, market position, and capabilities
Zap Energy is a fusion startup using sheared-flow-stabilized Z-pinch technology; raised $300M+; ranked #1 fusion company on TIME's GreenTech list; expanding into fission in 2026.
About
Zap Energy is a nuclear fusion company based in Everett, Washington, pioneering a radically simpler approach to fusion power. Unlike most fusion efforts that rely on complex and expensive magnetic confinement systems (tokamaks), Zap Energy uses sheared-flow-stabilized Z-pinch technology — a compact, magnet-free method that passes high-current electrical pulses through plasma to compress and heat it to fusion conditions. Founded by University of Washington researchers, the company has advanced through multiple generations of its FuZE device, most recently achieving plasma pressures up to 1.6 gigapascals in its FuZE-3 prototype.
Helion Energy is a leading private nuclear fusion company pursuing the world's first commercial fusion power plant, with a power purchase agreement with Microsoft for 2028 delivery. HQ: Everett, WA.
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.
