About
Tokamak Energy is a UK-based private fusion energy company developing compact spherical tokamak reactors and high-temperature superconducting (HTS) magnet technology as a faster, lower-cost path to commercial fusion power. Its approach uses a spherical tokamak geometry — a more compact, donut-shaped design compared to conventional tokamaks — combined with proprietary HTS magnets that enable higher magnetic field strengths at lower cost, which the company believes will accelerate the timeline to net energy gain and commercial viability. Tokamak Energy aims to deliver first fusion power to the grid by the early 2030s.
