China Achieves Fusion Breakthrough: "Artificial Sun" Produces First Plasma Discharge

Beijing, June 22, 2024: In a significant scientific breakthrough, China's private fusion company, Energy Singularity, has made a major leap in the field of fusion energy by building and successfully operating the world's first fully high-temperature superconducting Tokamak in a device nicknamed "artificial sun."

This device, named HH70, is located in Shanghai and is seen as a crucial step forward in developing fusion technology for potentially generating clean energy.

A Tokamak is a doughnut-shaped containment device capable of confining plasma and heating it to replicate the conditions found on the Sun. Its goal is to create a safe and virtually limitless supply of electricity. These devices are often referred to as "artificial suns."

This technology utilizes the extremely high temperatures produced by fusion reactions, where hydrogen atoms are fused into helium, releasing enormous amounts of energy. Tokamaks, which are large and expensive machines, are able to generate magnetic fields that help contain the particles within the plasma.

Significance of the Breakthrough:

Energy Singularity's success is significant because it demonstrates China's leadership in the field of fusion energy. This technology has the potential to provide clean and more sustainable energy compared to traditional sources, potentially aiding in tackling climate change.

Challenges Remain:

However, several challenges need to be overcome before fusion energy becomes commercially viable. Key challenges include heating the Tokamak hot enough to sustain fusion reactions, and doing so without using more energy than is produced.


China's success in fusion technology is a significant scientific achievement. It demonstrates the country's commitment to playing a leading role in the future of clean energy. It's important to note that fusion energy is still in its early stages of development, and there are many hurdles to overcome before it becomes commercially viable.
