The second unit of the “Chaotan One” power project was connected to the grid on May 30 at Liupanshui, Southwest China’s Guizhou Province. The project uses pressurized carbon dioxide to capture industrial exhaust and convert it into electricity.
The grid connection indicates that the construction of the world’s first demonstration project for supercritical carbon dioxide waste-heat power generation technology has been fully completed. The project, built by China National Nuclear Corporation, now has 30 megawatts of installed capacity.

The project’s first unit began commercial operations on Dec 20, 2025, and it has performed well so far. All indicators meet or exceed the design specifications, enabling the whole system and core devices to operate stably for a long time and under various circumstances.
With the second unit connected to the grid, the entire project will soon begin formal commercial operations.
