Commonwealth Fusion Systems

Develops and commercializes fusion energy systems

About Commonwealth Fusion Systems

Commonwealth Fusion Systems focuses on developing fusion energy as a clean and sustainable power source. The company utilizes advanced magnet technology, created in partnership with MIT, to build smaller and more affordable fusion systems called tokamaks. These devices use magnetic fields to confine plasma in a toroidal shape, which is an effective method for achieving fusion. Currently, CFS is manufacturing high-temperature superconducting magnets and constructing SPARC, the first commercially-relevant net energy fusion machine. The success of SPARC is intended to lead to the development of ARC, the first fusion power plant. CFS differentiates itself from competitors by its commitment to scientific integrity and a mission-driven approach, focusing on delivering cost-competitive fusion energy to help combat climate change. The ultimate goal is to provide a reliable and abundant energy source for energy providers and industries that require significant power.
