Shanghai-based fusion startup Energy Singularity has achieved a milestone and set a global record for a commercially constructed nuclear fusion device with its HH70 high-temperature superconducting (HTS) tokamak. The device demonstrated the ability to sustain a plasma current for 1,337 seconds.
Established in 2021, Energy Singularity marked a milestone for Chinese fusion energy in 2024, launching the world’s high-temperature superconducting (HTS) tokamak. Since its inception, the device has conducted 5,755 experiments and achieved remarkable results.
In this regard, Dong Ge, co-founder of Energy Singularity, said: “This breakthrough is not just about time; it shows that the deep integration of HTS and AI control technologies has achieved technical feasibility and paves the way for high efficiency of future fusion power plants.”
The innovative HH70 device boasts an impressive 96 percent localization in its intellectual property and serves as a crucial experimental platform. Building on this success, the company is now developing its successor, with the ultimate goal of achieving net profits in fusion energy.
