About

Commonwealth Fusion Systems (CFS) is a fusion energy company spun out of MIT's Plasma Science and Fusion Center in 2018, commercializing decades of fusion research through a proprietary approach using high-temperature superconducting (HTS) magnets. CFS's strategy centers on making fusion magnets much stronger than previously possible: HTS magnets can achieve field strengths of 20+ Tesla (more than twice conventional magnet capability), which allows fusion reactors to be dramatically smaller and cheaper — potentially shrinking a fusion power plant from stadium-scale to building-scale. The company's first demonstration reactor, SPARC, is under construction in Devens, Massachusetts.
