Sep 30, 2026, 12:01 AM ET * As part of the long-term supply agreement, Fujikura is investing in the expansion of its manufacturing capacity to provide more than 10,000 km (3 GA-m) of HighTemperature Superconducting (HTS) tape to support the commercial rollout of CFS' ARC power plants. * The agreement is the largest of its kind for HTS tape, a key milestone for the ARC power plant supply chain. DEVENS, Mass. and TOKYO, Sept. 30, 2026 /PRNewswire/ - Commonwealth Fusion Systems (CFS), the global leader in fusion energy, today announced a landmark supply agreement with Fujikura Ltd. as it accelerates the commercial rollout of ARC fusion power plants. CFS agreed to purchase more than 10,000 km (3 GA-m) of high-temperature superconducting (HTS) tape from Fujikura that the company will use in the development of its ARC power plants, starting with the first grid-scale plant being developed at the Fall Line Fusion Power Station in Chesterfield County, Virginia. Fujikura is investing in the expansion of its manufacturing capacity to enable the delivery of the HTS tape at scale. The agreement is the largest of its kind for HTS tape. "This partnership with Fujikura demonstrates how we're actively placing orders and getting ready to execute our ARC power plant once our SPARC fusion machine achieves Q>1," said Bob Mumgaard, CEO and Co-founder of Commonwealth Fusion Systems. "We're pleased to find partners like Fujikura that understand our manufacturing priorities, share our sense of urgency, and are willing to make the investments necessary to help us scale so that together we can meet future demand for this crucial energy source worldwide." The supply agreement is a major milestone toward the construction of ARC power plants and will help to strengthen the industrial supply chain essential to bring commercial fusion power to market. It also marks an important step in U.S.-Japan collaboration and in building the industrial ecosystem needed to support commercial fusion energy. "With this agreement, Fujikura will continue to strengthen its position as a key supplier of HTS tape for ARC power plants while building a long-term business platform for the 2030s and beyond, when commercial fusion power plants are expected to begin operation," said Naoki Okada, Representative Director, President and CEO of Fujikura Ltd. "Through these efforts, Fujikura aims to help support a sustainable energy future." About Commonwealth Fusion Systems Commonwealth Fusion Systems is the world's largest and leading private fusion company. The company's marquee fusion project, SPARC, will generate net energy, paving the way for limitless carbon-free energy. The company has raised $4 billion in capital since it was founded in 2018. SPARC(R), ARC(TM), and Fall Line(TM) Fusion Power Station are trademarks of Commonwealth Fusion Systems(R). About Fujikura Fujikura Ltd., founded in 1885, is a global technology company with more than 100 group companies worldwide. Building on over a century of expertise in connectivity technologies, Fujikura provides advanced solutions for optical communications, electronics, and automotive applications. Today, the company supports the rapid expansion of digital infrastructure and contributes to the development of next-generation energy technologies, including fusion energy. About Fusion Energy Fusion energy is released when light atomic nuclei, such as deuterium and tritium, fuse to form another nucleus, such as helium, in a reaction similar to the one that powers the sun. One gram of fusion fuel is estimated to produce energy equivalent to burning approximately eight metric tons of oil. Fusion is attracting growing attention because it is considered the "holy grail" of energy production. It is an "always on" power source that has no emissions, is scalable, safe, and can be sited essentially anywhere. The fuel can be sourced from seawater, making it essentially unlimited and easily accessible - meaning fusion can provide permanent energy security as well. Fusion power plants that use magnetic confinement require extremely strong magnetic fields to hold plasma at temperatures of about 100 million degrees Celsius. Fujikura's HTS tape combines high current-carrying performance with high mechanical strength in intense magnetic fields, making it suitable for the powerful superconducting magnets used to confine and control the plasma. By enabling stronger magnetic fields, HTS magnets can help make fusion power plants compact, which is expected to reduce the capital costs and make commercial fusion power plants more affordable and easier to build. Fujikura has already supported CFS' research and development by supplying HTS tape. *1 High-temperature superconductors (HTS) Fujikura's HTS is based on its proprietary IBAD (Ion Beam Assisted Deposition) process, developed in 1991. It exhibits zero electrical resistance even at liquid-nitrogen temperature (−196°C) and can carry large currents despite its small cross-section. Because it maintains a high critical current even in high magnetic fields, it is an essential material for realizing compact, high-field fusion energy reactors. *2 Magnetic-confinement (tokamak) approach A torus-shaped fusion energy device that uses a strong magnetic field to confine ultra-high temperature plasma. The strong magnetic fields are generated by toroidal field coils, poloidal field coils, and a central solenoid coil, all of which use high-temperature superconductors.

Commonwealth Fusion Systems' Brandon Sorbom and Helion's David Kirtley on bringing fusion to the grid at TechCrunch Disrupt 2026. CFS' Brandon Sorbom and Helion's David Kirtley join the Smart Systems Stage at TechCrunch Disrupt 2026 to discuss the breakthroughs moving fusion forw For decades, commercial fusion power has seemed perpetually out of reach. Now two companies are building toward something much more concrete: putting fusion-generated electricity on the grid. Commonwealth Fusion Systems (CFS) is building SPARC, a demonstration fusion machine intended to pave the way for its first commercial power plant, ARC. Helion is developing Orion, a 50-megawatt fusion power plant intended to supply electricity to Microsoft beginning in 2028. At **TechCrunch Disrupt 2026**, CFS co-founder and chief science officer Brandon Sorbom and Helion founder and CEO David Kirtley will take the **Smart Systems Stage for "Bringing Fusion to the Grid."** They'll discuss the breakthroughs moving fusion forward, the challenges that remain, and what it will take to deliver fusion power to the grid at scale. Want to hear what stands between today's fusion breakthroughs and commercial power? **Grab your pass and bring your co-founder, partner, or peer for 50% off their pass.** Discover the insights shaping the future of fusion, together. Moving fusion from science to commercial power. Sorbom co-founded CFS in 2018 with the goal of commercializing fusion energy in time to help combat climate change. As chief science officer, he leads the company's scientific direction and R&D and helps advance the design of ARC. The idea has roots in his work at MIT, where Sorbom was lead author of the paper proposing the original ARC design while earning his Ph.D. in nuclear science and engineering. Today, CFS is working toward ARC through SPARC, the company's demonstration fusion machine. In April, CFS became the first fusion company to apply to PJM Interconnection, the largest U.S. wholesale electricity market - a necessary step toward eventually connecting ARC to the grid. In July, the company raised another $1 billion, bringing its total funding to $4 billion. For founders and technology leaders, Sorbom brings a perspective that spans the journey from academic research to designing a commercial fusion power plant, and the scientific and engineering challenges that have to be solved along the way.

Putting fusion power to the test. Kirtley founded Helion to develop fusion technology that could ultimately deliver electricity at commercial scale. An NSF and NASA Advanced Concepts Fellow, he has expertise in high-Beta plasmas for energy and space propulsion applications and today leads Helion as it works toward commercial fusion power. In February, Helion announced that its Polaris prototype had heated plasma to 150 million degrees Celsius. The company is now developing Orion, a 50-megawatt fusion power plant intended to supply electricity to Microsoft as early as 2028. In June, Helion announced a key regulatory milestone on the path to building and operating the plant. Its Series G funding round, initially announced at $465 million in June, closed at $500 million in September. That timeline puts the questions at the heart of the Disrupt session into sharp focus. Scientific milestones matter, but commercial fusion also has to make the leap to a functioning power plant capable of reliably delivering electricity to customers.
