HPI(SH:600011) Yang Shi Xin Wen Ke Hu Duan·2025-09-26 02:52Core Insights - The world's largest coal-fired carbon capture demonstration project at Huaneng Gansu Zhengning Power Plant has successfully completed a 72-hour trial run and is now in commercial operation, marking a historic leap in CCUS technology from "ten-thousand-ton demonstration" to "million-ton industrial application" [1][2] - The project is a significant national technology demonstration and a first batch green low-carbon demonstration project by the National Development and Reform Commission, aimed at capturing CO2 from the flue gas of the power plant [1] Group 1 - The carbon capture rate of the project exceeds 90%, with an annual capacity to capture 1.5 million tons of CO2, equivalent to the annual emissions of 600,000 cars [2] - The captured CO2 has a purity of over 99% and can be compressed to a supercritical state for underground geological storage, as well as applications in enhanced oil recovery, green fuel synthesis, and mineralized building materials [1][2] - The project has achieved breakthroughs in key technologies, including the world's first "dual-tower" composite absorption tower and the largest deep saline aquifer multi-layer storage system in China, setting a new benchmark for low-carbon transformation in the coal power industry [2] Group 2 - CCUS stands for Carbon Capture, Utilization, and Storage, which is a key technology for achieving carbon neutrality in the future [3] - In coal-fired power plants, CO2 is separated from flue gas through a chemical reaction with alkaline absorbents, followed by dehydration, purification, and compression for various applications [3] - The captured CO2 can be utilized in chemical and biological fields, injected underground to enhance oil recovery, or safely stored in underground or marine environments [3]
