CFS was founded in 2018 as a spin-off from the Massachusetts Institute of Technology (MIT) Plasma Science and Fusion Center (PSFC). After initial funding of $50 million in 2018 from Eni, CFS closed its Series A in 2019 with a total of $115 million in funding from Eni, Breakthrough Energy Ventures, Khosla Ventures, and others. CFS raised an additional $84 million in Series A2 funding from Temasek, Equinor, and Devonshire Investors, as well as from previous investors.
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. This magnet technology will then be used to construct SPARC, a demonstration net energy tokamak. It then plans to build a power plant based on the ARC design. Both SPARC and ARC plan to use deuterium-tritium fuel.
