Private fusion energy developers have issued major procurement contracts for high-temperature superconducting tape. The industrial scaling of HTS magnets is crucial for achieving high plasma confinement fields within smaller tokamak footprints.
Supply Chain Bottlenecks
Global manufacturing capacity for specialized rare-earth barium copper oxide tape remains limited. Supply constraints pose a critical schedule risk for pilot reactors slated for late 2020s grid connection tests.
Commercial Readiness
Engineering emphasis has moved from plasma containment duration to thermal hydraulics and steady-state electrical power output efficiency.
