Through a strategic partnership, Mark & Wedell will integrate Faraday Factory Japan‘s cutting-edge REBCO 2G HTS tape into our superconducting current leads, powering the future of fusion energy. The collaboration pushes the boundaries for high-current applications, enabling the next generation of fusion reactors. The first implementation of this technology will be in current leads used at a cryogenic test facility in Europe.
Mark & Wedell (M&W) is proud to announce a strategic partnership with Faraday Factory Japan, a leader in high-temperature superconductor (HTS) technology. Through this collaboration, Mark & Wedell will integrate Faraday Factory’s next-generation REBCO (Rare Earth Barium Copper Oxide) 2G HTS tape into its advanced superconducting current leads, pushing the boundaries of high-current applications for fusion energy.
This partnership marks a significant step forward in developing robust components for fusion energy, a technology that promises a safe, viable, and virtually limitless power source. The design of M&W current leads in combination with Faraday Factory’s 2G HTS tape is uniquely capable of handling electrical currents up to 45 kA which is a critical performance requirement for the powerful magnets used in fusion reactors. By incorporating this cutting-edge material, Mark & Wedell is engineering current leads that can meet one of the toughest challenges in the field. The first implementation of this technology will be in current leads used at a cryogenic test facility in Europe.
The superior performance of Faraday Factory’s HTS tape is achieved through a multiyear development of sophisticated technology based on Ion Beam Assisted Deposition (IBAD) and Pulsed Laser Deposition (PLD) methods. This high-rate process creates a stable output of high quality HTS coatings with unparalleled current-carrying capability. The collaboration, which began in April 2025, leverages this unique material to create current leads capable of operating even under the extreme conditions of fusion reactors.
“With this significant partnership, Mark & Wedell once again demonstrates our unique expertise in optimizing solutions for superconducting current leads,” said Torben Ekvall, CEO of M&W. “This partnership not only expands our capabilities to a new scale but also embraces the next generation of superconducting REBCO tape, reinforcing our commitment to deliver world class current leads.”
Dr. Sergey Lee, CEO of Faraday Factory Japan, commented, “We are delighted to partner with Mark & Wedell, a company renowned for its engineering excellence in cryogenic and superconducting systems. Integrating our advanced superconducting tape product into their high-performance current leads is a perfect synergy of materials science and application engineering. Together, we are providing an essential component for the future of fusion energy.”
Over the past 25 years, Mark & Wedell has provided Big Science customers with current leads designed for currents ranging from 100 Amps (A) to 50,000 A. These customers include CERN, GSI, CEA and INFN etc. For the past few years, M&W has pursued a twotrack strategy that on the one hand continues to deliver and develop products to the Big Science market, and on the other hand pursues opportunities outside of Big Science, especially in the electricity transmission market and emerging Fusion market.
Faraday Factory Japan is a leading developer and manufacturer of advanced secondgeneration (2G) high-temperature superconducting (HTS) tapes. Utilizing proprietary manufacturing processes, the company produces high-performance REBCO tapes designed for demanding applications in fusion energy, medical devices, and nextgeneration power infrastructure.
