The Tough Tech problem we are solving
Fusion energy is considered the holy grail of energy: its energy density is orders of magnitude higher than fossil fuels without any carbon emissions; it uses less land and is more reliable than renewable energy; and it doesn't produce radioactive waste or come with the risk of catastrophic meltdown like nuclear fission energy. However, fusion reactors have never been able to produce more energy than they consume. 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.
About our solution
Commonwealth Fusion Systems (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, which is expected to demonstrate net energy by 2027. SPARC will pave the way for the world’s first fusion power plant, called ARC. The company's first grid-scale ARC reactor is currently under construction in Chesterfield County, Virginia, and is expected to power about 150,000 homes by the early 2030s.
