Core Insights - The world's largest coal-fired carbon capture demonstration project at Huaneng Gansu Zhengning Power Plant has completed a 72-hour trial run and is officially operational, marking a significant leap in China's carbon capture, utilization, and storage (CCUS) technology from "ten-thousand-ton demonstration" to "million-ton industrial application" [1][2] Group 1: Project Overview - The project is a major national technology demonstration initiative and one of the first green low-carbon demonstration projects approved by the National Development and Reform Commission [1] - It focuses on carbon capture from the flue gas of Unit 1 of Huaneng Gansu Zhengning Power Plant, achieving a carbon dioxide purity of over 99% [1] - The captured carbon dioxide can be compressed to a supercritical state for underground geological storage and utilized in oil field enhanced recovery, green fuel synthesis, and mineralized building materials, thus completing the entire "capture-utilization-storage" industrial chain [1] Group 2: Technological Innovations - The project has overcome multiple technical bottlenecks in key areas such as carbon capture, compression, and storage, achieving several "global firsts" and "domestic innovations" [1] - Core equipment has been fully domestically produced, enhancing the project's sustainability and reducing reliance on foreign technology [1] - An innovative "two-tower integration" design for the composite absorption tower has been adopted, integrating flue gas pre-washing and carbon capture, which addresses energy consumption issues associated with traditional processes [1] Group 3: Efficiency and Impact - The project has developed China's first eight-stage integrated gear-type carbon dioxide compressor, capable of meeting supercritical pipeline transportation requirements, significantly improving transportation efficiency while reducing energy consumption and costs [2] - The carbon capture rate of the project exceeds 90%, with an annual capture capacity of 1.5 million tons of carbon dioxide, equivalent to the annual emissions from 600,000 cars [2] - This initiative supports large-scale industrial deep emissions reduction for coal-fired power plants, promoting green and clean development in the coal power sector and aiding in achieving carbon neutrality goals [2]
