The surest path to limitless, clean fusion energy
What we do
Decades of worldwide, government-sponsored research in fusion science have established the tokamak-based configuration as the highest performing approach to fusion. Yet in the past, tokamaks had to be enormous in size to produce net energy from fusion. CFS is using revolutionary high temperature superconducting magnets developed in collaboration with MIT to build smaller and lower-cost tokamak fusion systems. CFS is manufacturing these magnets and building the world’s first commercially-relevant net energy fusion machine, called SPARC. SPARC will pave the way for the world’s first fusion power plant, called ARC. CFS has assembled a world-class team working to design, build, and scale fusion power plants that will deliver cost competitive, clean fusion energy to combat climate change.
Company's story
Commonwealth Fusion Systems is collaborating with MIT’s Plasma Science and Fusion Center to build SPARC, the world’s first fusion device that produces plasmas which generate more energy than they consume, becoming the first net-energy fusion machine. SPARC will pave the way to safe, carbon-free, limitless fusion power. This compact high-field tokamak will be built with HTS magnets, allowing for a smaller device than previous magnet technology. SPARC is an important step to accelerate the development of commercial fusion energy.
