In a significant move toward commercializing fusion energy, the US-based firm Commonwealth Fusion Systems (CFS) has commissioned a record-breaking 10,000 kilometers of high-temperature superconducting (HTS) tape from Japan’s Fujikura. This massive supply agreement is designed to fuel the development of magnets for the company’s upcoming ARC fusion power plants, with the first grid-scale facility slated for construction in Chesterfield County, Virginia. By locking in this supply, CFS aims to accelerate its timeline, with the company’s leadership expecting to connect the Virginia plant to the grid by the early 2030s.

This deal marks a major expansion of a long-standing collaboration between the two companies, as Fujikura’s technology is already integral to the magnets used in CFS’s Sparc project, which is set to go online in 2027. While financial details remain confidential, the partnership highlights the transition of fusion energy from a purely scientific pursuit into a global industrial enterprise. As CFS looks to scale production, it is leveraging a supply chain of over 1,000 vendors worldwide, viewing this long-term commitment with Fujikura as a cornerstone of the infrastructure needed to bring sustainable fusion power to the commercial market.
