Commonwealth Fusion Systems
Building compact tokamak fusion power plants
Commonwealth Fusion Systems (CFS) is a leading commercial fusion energy company that emerged from MIT in 2018. The company focuses on developing compact tokamak-based fusion power plants utilizing high-temperature superconducting (HTS) magnets. CFS aims to provide cost-competitive, clean fusion energy to help combat climate change and reduce reliance on fossil fuels.
CFS has raised over $2 billion in private capital, making it the most funded fusion company to date. The company operates from a 60-acre campus in Devens, Massachusetts, where it conducts research and manufacturing. Its key projects include SPARC, the first commercially relevant net energy fusion device, and ARC, a follow-on fusion power plant designed to deliver grid-scale power. CFS emphasizes collaboration with suppliers, researchers, and policymakers to foster a global ecosystem for clean energy solutions.
