2060 Fusion Power Integration via High-Temperature Superconducting Tokamak Designs

Advancing Compact Fusion Reactors Using Rare-Earth Barium Copper Oxide (REBCO) Magnets

The Promise of Fusion Energy

The quest for sustainable, large-scale energy solutions has led to significant advancements in nuclear fusion technology. Unlike fission, fusion offers a virtually limitless energy source with minimal radioactive waste and no greenhouse gas emissions. By 2060, the integration of high-temperature superconducting (HTS) tokamak designs could revolutionize grid-scale energy deployment, making fusion power a tangible reality.

High-Temperature Superconducting Tokamaks: A Paradigm Shift

Traditional tokamaks rely on low-temperature superconductors, which require extensive cryogenic cooling systems. High-temperature superconducting materials, such as Rare-Earth Barium Copper Oxide (REBCO), operate at higher critical temperatures, reducing cooling costs and improving magnetic field strength. This breakthrough enables:
