In a historic leap for clean energy innovation, the world’s first commercial supercritical carbon dioxide (scCO₂) power generation unit began operations in Liupanshui, Guizhou Province, on December 20, 2025. Developed by the China National Nuclear Corporation (CNNC), the project, named Super Carbon No.1, represents a transformative advancement in thermoelectric conversion technology.
The system heats and pressurizes liquid carbon dioxide into a supercritical state, a phase where it exhibits properties of both liquid and gas, to drive electricity-generating turbines. This method achieves higher efficiency and lower emissions compared to traditional coal-fired plants, aligning with global decarbonization goals.
Analysts highlight the unit’s potential to reshape Asia’s energy landscape, particularly for industrial hubs seeking sustainable alternatives. "This milestone underscores China’s commitment to pioneering climate solutions," said a CNNC spokesperson. The technology is expected to attract overseas investors eyeing scalable clean energy projects.
Guizhou, known for its renewable energy initiatives, now positions itself as a testing ground for next-generation power systems. Researchers and business leaders alike will monitor the unit’s performance, which could inform similar ventures across the region.
