Commonwealth Fusion Systems
Commonwealth Fusion Systems
01 Executive_Summary
Founded 2018, spun out from MIT Plasma Science and Fusion Center (PSFC). Uses high-temperature superconducting (HTS) magnets + tokamak design (NOT FRC). SPARC facility ~75% complete (2025). HTS magnets verified at 20 tesla (world record, Sept 2021). 6 IEEE Transactions papers confirming magnet design (March 2024). Tokamak assembly began March 2025 — cryostat base installed. Target: Q>1 demonstration. ARC power plant: Chesterfield County, Virginia, early 2030s. $2B+ raised (Bill Gates, Eni, others). Competes with FRC approaches for funding but uses fundamentally different technology.
