World’s First Power Plant Using Supercritical CO₂ Goes Live in China

Super Carbon No. 1 Power Plant Begins Operation

According to НВ — Техно: A 30-megawatt Chinese power plant that relies on supercritical carbon dioxide has officially entered service. The first generator unit was activated on December 20, followed by a second 15-megawatt unit on May 30, both located at the Shougang Shuicheng steel mill in Liupanshui. Known as the Super Carbon No. 1 project, the technology behind it was jointly developed by three entities: the CNNC Institute of Nuclear Energy, Jigang International, and Shougang Shuicheng. This initiative marks a notable step in integrating advanced energy solutions into heavy industry.

Capacity and Technology

The facility’s total output reaches 30 megawatts, combining the operation of both power blocks. The system captures waste heat generated during steel production, making it a key component in efforts to boost energy efficiency within the metallurgical sector.

“With both power units now running, the Super Carbon No. 1 demonstration project will deliver a stable installed capacity of 30 MW, establishing it as the largest, most sophisticated, and most mature supercritical carbon dioxide power generation project currently in operation.” - CNNC representatives

Extended operation has also confirmed the reliability of the project’s core equipment and the stability of the entire system under various working conditions. This technology uses carbon dioxide in a supercritical state as its working fluid, designed specifically to recover excess heat in energy-intensive industries like steelmaking. The Super Carbon No. 1 project could play a significant role in China’s broader efforts to cut emissions and improve energy efficiency.

The launch of the Super Carbon No. 1 power plant represents a meaningful advance in China’s environmental initiatives aimed at reducing greenhouse gas emissions. Employing supercritical carbon dioxide as a working fluid proves to be a promising approach for enhancing industrial energy efficiency, particularly in the energy-heavy steel sector. This project may serve as a blueprint for similar undertakings in other industries and countries pursuing sustainable development.

As China continues to innovate in the energy sector, another significant development is underway with the relocation of a massive offshore power facility measuring 44 meters in height. This ambitious project highlights the nation's commitment to enhancing its energy infrastructure and reducing carbon emissions.
