CFS Sells Fusion Magnet Tech to Realta
2 Apr
Summary
- CFS announced a significant deal to sell superconducting magnets to Realta Fusion.
- This deal is CFS's largest of its kind to date, boosting revenue.
- Both companies leverage advanced magnet technology for fusion reactor designs.
Commonwealth Fusion Systems (CFS) has entered into its largest agreement to date, selling high-temperature superconducting magnets to the fusion startup Realta Fusion. This deal highlights CFS's strategy to commercialize its advanced magnet technology to generate revenue.
CFS previously supplied magnets for the WHAM experiment, which underpins Realta's magnetic mirror reactor approach. This reactor design confines plasma using powerful magnets, with Realta planning to expand its size for increased power output. These magnets are less powerful and cheaper than those used in other designs, potentially lowering per kilowatt-hour costs.
CFS itself is developing tokamak reactors, with its first commercial-scale plant, Arc, planned for Virginia. The company's founding in 2018 stemmed from the realization that new high-temperature superconductors could enable viable tokamak designs. Similarly, Realta was founded when physicists saw this new magnet technology as a game-changer for magnetic mirror reactors.
In addition to Realta and WHAM, CFS has licensed its magnet technology to Type One Fusion for a stellarator reactor design. These agreements will help CFS recoup its significant investment in a specialized magnet factory built over seven years. The factory, which produced magnets for CFS's Sparc demonstration reactor, will remain operational between projects.
CFS has raised nearly $3 billion, positioning it favorably to fund key facilities like its magnet factory. By offering its technology as a service, CFS not only supports the broader fusion industry but also secures further investment.
