Commonwealth Fusion Systems is an American company aiming to build a compact fusion power plant based on the ARC tokamak concept.[1] The company is based in Cambridge, Massachusetts.

History[edit]

CFS was founded in 2018 as a spin-off from the Massachusetts Institute of Technology (MIT) Plasma Science and Fusion Center (PSFC).[2] After initial funding of $50 million in 2018 from Eni,[1] CFS closed its Series A in 2019 with a total of $115 million in funding from Eni,[3] Breakthrough Energy Ventures, Khosla Ventures, and others.[4][5] CFS raised an additional $84 million in Series A2 funding from Temasek, Equinor, and Devonshire Investors, as well as from previous investors.[6]

Technology[edit]

The company plans to focus on proving new yttrium barium copper oxide (YBCO) high-temperature superconducting magnet technology, demonstrating a large-bore, high-field (20 Tesla) magnet in 2021.[6] This magnet technology will then be used to construct SPARC, a demonstration net energy tokamak.[7] It then plans to build a power plant based on the ARC design.[1] Both SPARC and ARC plan to use deuterium-tritium fuel.
