A Chinese company announced success in creating the latest fusion reactors

New record in commercial thermonuclear energy

A young Shanghai company *Energy Singularity* announced a significant achievement: its own tokamak HH70, built with high‑temperature superconductors (HTS), set the world record among commercial reactors. During a continuous cycle lasting 1,337 seconds (over 22 minutes) it was possible to maintain a stable plasma current, confirming the device’s reliability.

Parameter Value Commissioning date Cycle duration Number of experiments
- — June 2024 1,337 s (22 min) 5,755

Why HH70 is considered a next‑generation tokamak
* High‑temperature superconductors: all magnets use HTS, allowing operation at higher temperatures compared to traditional low‑temperature superconductors (LTS) used in projects such as ITER.

* Cost‑effectiveness and ease of operation: raising the temperature of the magnetic system reduces cooling requirements and, consequently, maintenance costs.

Key success factors
1. Continuous plasma control optimization – implemented with artificial intelligence (AI).

2. High‑temperature superconductors – provide reliability and energy efficiency for the magnetic system.

The company emphasizes that it is the combination of AI and HTS that became “the two key ingredients” of the record.

Future plans
* HH170 – the next experimental reactor, planned to be launched in 2027.

* Goal: achieve a positive output energy coefficient \(Q = 10\) (energy produced is ten times the energy spent heating the plasma).

* By 2030 the company intends to move toward building a full‑scale thermonuclear power plant on HTS.

Comparison with other projects
Many new generations of tokamaks and reactors are being implemented worldwide, promising to “ignite an artificial sun” in the first half of the 2030s.

The flagship ITER project, however, has postponed reactor launches until the late 2030s or even the 2040s, showing a slower progression.

Conclusion: *Energy Singularity* successfully demonstrated that high‑temperature superconductors combined with AI can significantly accelerate the development of thermonuclear energy and bring it closer to commercial application.
