Problem
Current large‑scale energy generation relies on fossil fuels and nuclear fission, which produce greenhouse‑gas emissions or generate long‑lived waste, and existing fusion research devices are massive, costly, and have not yet demonstrated a path to commercial power.
Solution
Tokamak Energy addresses these challenges by developing compact spherical tokamaks that use high‑temperature superconducting (HTS) magnets to create the strong magnetic fields needed for plasma confinement in a much smaller, more affordable device. Their HTS technology operates at higher temperatures than conventional superconductors, reducing cooling requirements and enabling higher magnetic field strengths. The company’s ST40 prototype has achieved plasma temperatures of 100 million °C, demonstrating the feasibility of reaching fusion‑relevant conditions in a compact form factor. By integrating advanced magnet design, modular engineering, and strategic partnerships, Tokamak Energy aims to deliver a scalable fusion power solution that can be commercialized in the 2030s.
Target Audience
Primary customers include utility companies, government energy agencies, and industrial partners seeking clean, on‑demand power, as well as research institutions and fusion‑technology developers requiring advanced HTS magnet and compact tokamak solutions.
