Commonwealth Fusion Systems

Commonwealth Fusion Systems (CFS) was spun out of MIT in 2018 to develop and commercialize fusion energy. The company is headquartered in Devens, Massachusetts, and has raised over $2 billion to build compact tokamak fusion power plants. Its core technology relies on high-temperature superconducting (HTS) magnets to create the conditions necessary for fusion.

The company's primary projects are SPARC and ARC. SPARC is designed to be the world's first commercially relevant net energy fusion machine, intended to demonstrate net energy gain. This is a critical step toward ARC, the company's planned commercial fusion power plant. The first ARC facility is slated for Chesterfield County, Virginia, and is designed to deliver 400 megawatts of clean, zero-carbon power to the electrical grid.

CFS operates at the intersection of fusion energy, power generation, and clean energy. The firm aims to combine decades of academic fusion research with private sector speed and agility to bring fusion power to market. Its stated mission is to accelerate the transition to fusion energy as a means of combating climate change.
