At 21:45 on May 30, the second unit of the “SuperCarbon-1” Global Demonstration Project—the world’s first 2×15 MW supercritical carbon dioxide (sCO₂) waste heat power generation project—successfully achieved grid-connected power generation at the plant of Shougang Shuicheng Iron & Steel Group in Liupanshui, Guizhou Province, following the smooth issuance of the grid connection command.
This marks the full completion of the world’s first supercritical CO₂ waste heat power generation technology demonstration project, jointly developed by the China Nuclear Power Research and Design Institute (CNPRI) of China National Nuclear Corporation (CNNC), Jigang International, and Shougang Shuicheng Iron & Steel.
After both units are fully put into operation, the “SuperCarbon-1” demonstration project will have a stable installed capacity of 30 MW, becoming the world’s largest, most technologically advanced, and most operationally mature benchmark project for supercritical CO₂ power generation.
The first unit of the “SuperCarbon-1” Global Demonstration Project was officially put into commercial operation on December 20, 2025. To date, it has operated stably for more than five months, with all performance indicators meeting or exceeding design standards. The reliability of core equipment and system stability have withstood long-term practical tests under multiple operating conditions. The second unit, after intensive commissioning, has successfully connected to the grid and will soon enter formal commercial operation. The full completion of the “SuperCarbon-1” Global Demonstration Project has fully proven the technological advancement, system reliability, and operational flexibility of supercritical CO₂ waste heat power generation technology.
