Private fusion energy developers are encountering industrial supply bottlenecks in high-temperature superconducting (HTS) tape. While plasma containment physics remain the core research focus, component manufacturing scalability has emerged as the primary operational bottleneck.
Industrialization Barriers
Global production of rare-earth barium copper oxide tape currently satisfies less than 30% of projected demonstration-plant demands. Consequently, leading fusion ventures are vertically integrating tape fabrication to mitigate project timeline slippage.
