The brief

Analyst view
  • HH70 achieved first plasma in June 2024 as the world's first all-HTS tokamak, later sustaining 1,337 seconds of steady plasma.
  • Company holds record for 26.7 Tesla cryogen-free HTS magnet achieved June 2026, the highest field for insulated HTS magnets.
  • HH170 targets 10 Tesla center field and 150 cm major radius, with Q>2 demonstration by 2027.

Technical approach

As reported
HTS Magnets

High-temperature superconductor coils

HTS materials superconduct at ~77 K instead of ~4 K, reducing cooling costs and enabling compact designs.

Compact Design

Smaller, higher-field tokamaks

HTS magnets enable tokamaks with smaller radius but higher field, reducing size and cost vs conventional designs.

Steady-State Operation

Continuous plasma confinement

HH70's 1,337-second run demonstrates steady-state operation, required for commercial fusion reactors.
