Commonwealth Fusion Systems (CFS) hosted visiting officials for a tour and ribbon-cutting ceremony to officially open its new headquarters in Devens, Mass., on February 10. Energy secretary Jennifer Granholm, Sen. Elizabeth Warren (D., Mass.), and Sen. Edward Markey (D., Mass.) were among the national, state, and local leaders invited to celebrate what CFS heralded as a “fusion energy campus.”

The Massachusetts Institute of Technology’s Plasma Science and Fusion Center (PSFC) recently announced it will expand its involvement in fusion energy research and education under a new five-year agreement with Commonwealth Fusion Systems (CFS), a fusion energy company that got its start at MIT and is now building what it says will be the world’s first net-energy fusion machine—the demo-scale SPARC.
“CFS will build SPARC and develop a commercial fusion product, while MIT PSFC will focus on its core mission of cutting-edge research and education,” said PSFC director Dennis Whyte in describing the collaboration.

The U.K. government has just published Towards Fusion Energy: The UK Government’s Fusion Strategy, which sets out the goal of the United Kingdom's moving from “a fusion science superpower to a fusion industry superpower,” with a prototype fusion power plant being built in the country by 2040.
While a slightly ambitious plan, there are now about 20 startup companies working to achieve a Wright brothers’ moment in fusion sooner than that. This includes Commonwealth Fusion Systems, which is aiming for a working fusion power plant by 2030 and is the subject of Rivka Galchen’s October 4 New Yorker article, “Can Nuclear Fusion Put the Brakes on Climate Change?”

A high-temperature superconducting magnet reached and maintained a magnetic field of more than 20 tesla in steady state for about five hours on September 5 at MIT’s Plasma Science and Fusion Center. Not only is the magnet the strongest high-temperature superconducting (HTS) magnet in the world by far, it is also large enough—when assembled in a ring of 17 identical magnets and surrounding structures—to contain a plasma that MIT and Commonwealth Fusion Systems (CFS) hope will produce net energy in a compact tokamak device called SPARC in 2025, on track for commercial fusion energy in the early 2030s.
