Country: USA | Funding: $2.9B (+)

Commonwealth Fusion Systems is collaborating with MIT to create SPARC - the world's first fusion device that produces plasma that generates more energy than consumes. This compact, high-field tokamak will be built using high-temperature superconducting (HTS) magnets. CFS technology uses the new superconductor Rare Earth Barium Copper Oxide (REBCO) to produce the most powerful and most compact fusion magnets. Once SPARC is built, the company plans to build the world's first fusion power plant capable of generating hundreds of megawatts of power. CFS research is funded by the U.S. Department of Energy.
