In a significant leap for clean energy technology, China has successfully put into operation the world’s first coal-fired power generation unit to achieve a thermal efficiency exceeding 50%. This milestone coincides with a historic shift, as coal’s share in China’s power generation fell below 50% for the first time in the first half of this year.
Efficiency Breakthrough
The announcement was made by Li Chao, Deputy Director of the Policy Research Office of the National Development and Reform Commission (NDRC), during the NDRC’s August press conference. The newly operational unit represents a major advancement in the efficiency of coal-fired power plants, a sector undergoing significant transformation.
This development is part of a broader national strategy. The NDRC plans to intensify efforts in implementing a three-year action plan focused on energy conservation and carbon reduction in the coal power industry. The goal is ambitious: by the end of 2028, the proportion of coal power facilities meeting energy efficiency benchmarks is targeted to increase by 15 percentage points.
Technological Prowess
The groundbreaking unit is the No. 1 unit of the 630℃ ultra-supercritical plant at Datong Yuncheng, developed by China Datang Corporation. It stands at the forefront of China’s advanced clean coal power generation technology.
Beyond achieving over 50% thermal efficiency, the project also successfully tackled a critical technical challenge: the welding of a new generation of domestically produced G115 steel. This achievement paves the way for the large-scale, independent application of this advanced material in domestic power engineering projects.
This breakthrough follows earlier reports, such as the completion of single-unit debugging for the world’s first 630℃ thermal power unit in March of this year, signaling the final push towards its grid connection and power generation.
Industry Transformation
The dual development – a record-breaking efficiency milestone for a single unit and a declining overall share of coal in the energy mix – highlights China’s commitment to modernizing its energy sector. While coal’s dominance wanes, the remaining coal power infrastructure is becoming significantly more efficient and environmentally conscious.
The NDRC’s continued focus on energy-saving and carbon-reduction upgrades in the coal sector underscores a strategic approach to balancing energy security with environmental sustainability. The push for higher efficiency benchmarks aims to reduce the carbon footprint of coal power, making it a more viable component of China’s energy landscape during the transition to cleaner sources.
This technological leap not only showcases China’s engineering capabilities but also sets a new global standard for coal-fired power generation, potentially influencing future energy infrastructure development worldwide.
