What SuperPower does

SuperPower Inc. is a U.S.-based manufacturer of second-generation high-temperature superconducting (2G-HTS) wires built on REBCO (Rare Earth Barium Copper Oxide) technology. Founded in 2000 as a spinout of Intermagnetics General Corporation and headquartered in Glenville, New York, the company has operated as a wholly-owned subsidiary of Japan's Furukawa Electric Co., Ltd. (TSE:5801) since February 2012. Its product portfolio centers on 2G-HTS wire offered in two formulations: the AP formula (critical current 120-160 A/4mm at 77K self-field) for general applications and the HM formula (80-120 A/4mm at 77K self-field) optimized for in-field performance at cryogenic temperatures of 4.2K and 20K. Wires are available in widths of 2 to 12 mm and piece lengths up to 900 meters, manufactured through a vertically integrated process using magnetron sputtering, IBAD (Ion Beam Assisted Deposition), MOCVD REBCO deposition, and proprietary non-contact TapeStar critical current measurement.

The company serves enterprise customers in fusion energy, ultra-high-field NMR spectroscopy, scientific research, and adjacent high-field magnet applications. Named customers include Tokamak Energy (ST80-HTS and ST-E1 fusion pilot plant), Bruker (1.1 and 1.2 GHz NMR magnets), the National High Magnetic Field Laboratory, and General Atomics. Revenue is generated through direct hardware sales of specialty superconducting wire on a quote-based pricing model, with distribution handled via Furukawa Electric's regional sales agencies across Europe, Japan, China/Hong Kong/Taiwan, and India. The Quick Ship inventory program supports shorter lead-time orders. Technical milestones include delivery of 9.7 km of wire for the Albany Cable Project, a 790 m single-piece length achievement, cables exceeding 10,000 Amperes in demonstration, and magnetic field intensity exceeding 40 Tesla in collaboration with NHMFL.

SuperPower's go-to-market is enterprise field sales targeting technical buyers at fusion developers, national laboratories, and scientific instrument manufacturers. The 20+ year technology track record, proprietary MOCVD/IBAD process IP, capital-intensive 48,000 sq ft manufacturing facility, and access to Furukawa Electric's global sales and parent balance sheet constitute the structural basis of its commercial position. Strategic priorities articulated through partnerships and public programs center on fusion energy as the primary growth vertical, with secondary positioning in scientific instrumentation, energy and grid applications, and future mobility concepts.

Core offering

SuperPower Inc. manufactures and sells second-generation high-temperature superconducting (2G-HTS) wires based on REBCO (Rare Earth Barium Copper Oxide) technology. The wires transport current with zero resistivity at cryogenic temperatures and are sold in multiple widths, lengths, and formula variants (AP and HM) for fusion, NMR, accelerator, and power applications. The company also offers a Quick Ship inventory service for shorter wire lengths ready within one week.

Product overview

SuperPower Inc. is a leading manufacturer of second-generation high-temperature superconducting (2G-HTS) wires based on REBCO (Rare Earth Barium Copper Oxide) technology. The company's core product portfolio consists of 2G-HTS wire offerings available in two formula variants: the AP formula (standard performance, 120-160 A/4mm at 77K self-field) and the HM formula (optimized for in-field performance at cryogenic temperatures of 4.2K and 20K for fusion applications). Products are offered in various widths (2-12mm), piece lengths (200-900m), and stabilizer configurations (Stabilizer-Free SF type or Surround Cu Stabilizer SCS type). The company also provides a Quick Ship inventory service for shorter wire lengths with rapid delivery. All products are manufactured at the company's facility in Glenville, NY and supplied through Furukawa Electric Group's global sales network.
