The mass production of High-Temperature Superconducting (HTS) tape is poised to become a cornerstone of the future high-tech economy, with the fusion industry leading a significant surge in demand and manufacturing scale-up. Andrew Côté, a nuclear fusion engineer at Stellerator Systems and a scout at Andreessen Horowitz (a16z), underscored this transformative potential, stating, "You have no idea how important mass produced HTS tape will be for the high tech economy of the future."
Côté highlighted the fusion industry as the initial catalyst, projecting that from there, HTS tape will revolutionize transportation, medical imaging, power generation, and transmission, eventually becoming "as cheap as wire at scale." This sentiment is echoed by industry trends, as the nuclear fusion sector is driving an explosive growth in HTS wire demand, anticipated to jump from 5,000 km to 1.5 million km in the next 15 years. This massive increase is pushing manufacturers to ramp up production capabilities.
Companies like Japan's Faraday Factory, now recognized as the world's largest producer of HTS tape, have already delivered over 5,000 km of HTS to fusion companies. The rapid rise of commercial compact fusion devices has triggered this demand, creating substantial opportunities for the HTS tape industry. Pulsed laser deposition (PLD) has been instrumental in the fabrication of REBCO-type HTS wires, with current annual global production capacity exceeding 5,000 km, and some estimates reaching 10,000 km.
HTS tapes are critical for enabling high magnetic fields in compact fusion reactors, which are essential for confining plasma. Beyond fusion, the technology's ability to carry high currents with minimal resistance at relatively higher temperatures than traditional superconductors makes it attractive for diverse applications. These include advanced power grids, more efficient electric motors, and even data centers, where it could address last-mile power challenges.
The scaling up of HTS tape manufacturing is seen as crucial for achieving milestones in fusion energy development, with many fusion companies targeting demonstration plants by 2027–2028. While current HTS tape costs range from $15–30 per meter, the industry's focus on achieving economies of scale aims to significantly reduce these prices, making the technology more accessible across various sectors.
