From November 5th to 10th, during the 7th China International Import Expo (CIIE), “HH70” was showcased in the “Comprehensively Deepening Reforms to Promote Development” section of the China Pavilion at the Expo.

HH70 is the world’s first fully high-temperature superconducting tokamak device independently developed and constructed by Energy Singularity in February 2024, and it successfully achieved first plasma in June. The completion and operation of HH70 have taken the lead in the world in completing the engineering feasibility verification of high-temperature superconducting Tokamak, marking that China has gained a first-mover advantage in the key field of high-temperature superconducting magnetic confinement fusion.
The toroidal magnetic field (B0) of HH70 is 0.6 Tesla, with a plasma major radius of 0.75 meters. Its magnet system consists of 26 high-temperature superconducting magnets. Designed, developed, and constructed by Energy Singularity, HH70 has independent intellectual property rights, with a localization rate exceeding 96%.
