Helion Energy

Helion develops a pulsed fusion system that directly recovers electricity like regenerative braking, uses deuterium and helium-3 as cleaner fuel, and operates smaller fusion devices that can adjust power output based on demand, avoiding the energy losses of traditional steam-turbine approaches.

Helion is the first and only private fusion project to reach fusion-relevant plasma conditions of 9+ keV Ions (100 million degrees Celsius), demonstrate 95% energy recovery efficiency, and sustain plasmas with lifetimes greater than 1ms. The company has received investment from Y Combinator and Mithril Capital, with early and sustained support from Mithril.
