Helion

Helion Energy, Inc. is a fusion research company based in Everett, Washington, founded in 2013. The company is focused on developing magneto-inertial fusion technology to produce clean and affordable electricity from aneutronic fusion, utilizing fuel derived from water. Helion aims to build the world's first fusion power plant, positioning itself to replace fossil fuels with reliable baseload fusion power for various applications, including homes and businesses. The company is advancing its fusion reactor technology through staged magnetic compression of Field Reversed Configuration (FRC) plasmas. Key prototypes include Polaris, which is set to be operational by mid-2025, and the under-construction Copernicus, aimed at demonstrating net energy viability. Helion also plans to design the Orion prototype, a 50 MW fusion plant intended to supply power to Microsoft datacenters by 2028. The company is targeting commercial plants for deployment in the early 2030s and is exploring additional solutions like energy storage and EV powertrain components.
