Commercial Fusion Energy

Technical Overview

REBCO HTS magnets are revolutionizing the development of tokamak fusion reactors, enabling players like ITER, Commonwealth Fusion's SPARC, and TAE Technologies to push the boundaries of clean energy.

Our advanced high-field D-shaped toroidal field coils are capable of generating 20+ Tesla magnetic fields at 20K. REBCO is currently the only known material capable of sustaining the 20T+ magnetic confinement fields required for compact, net-energy-positive fusion reactors.

Benefits & Applications

  • Compact Reactor Size: Enables designs up to 40% smaller than traditional Low Temperature Superconductor (LTS) architectures.
  • No Liquid Helium Needed: Higher operational temperatures mean expensive, complex liquid helium cooling systems are entirely eliminated.
  • Faster Ramp Rates: Exceptional thermal stability translates to dramatically faster magnetic field ramp rates.
  • Global Deployments: Being applied in leading projects including ITER (France), SPARC (MIT/CFS), General Fusion, and TAE Technologies.
