全球首台！二氧化碳能用来发电了

Core Viewpoint - The successful operation of the world's first commercial supercritical carbon dioxide power generation unit, "Super Carbon No. 1," in Liupanshui, Guizhou, marks a significant advancement in power generation technology, utilizing supercritical carbon dioxide for efficient energy conversion [1][2]. Group 1: Technology and Efficiency - "Super Carbon No. 1" is a 15-megawatt supercritical carbon dioxide waste heat power generation project developed by China National Nuclear Corporation and partners, representing a shift from traditional steam-based power generation methods [1]. - The new technology operates with supercritical carbon dioxide at temperatures above 31 degrees Celsius and pressures exceeding 73 atmospheres, enhancing the efficiency of power generation by over 85% compared to previous methods [2]. - The project is expected to generate an additional 70 million kilowatt-hours of electricity annually, increasing revenue by nearly 30 million yuan without changing existing sintering processes [2]. Group 2: Industry Impact and Applications - The steel and cement industries are major energy consumers and carbon emitters, making them key areas for implementing carbon reduction strategies. Efficient utilization of industrial waste heat is crucial for energy conservation and carbon reduction [2]. - The "Super Carbon No. 1" technology offers advantages such as compact systems, fewer auxiliary systems, and faster response times, potentially reducing space requirements by 50% [2]. - The technology is anticipated to revolutionize waste heat utilization not only in the steel industry but also in other sectors like cement and glass, contributing to broader energy efficiency improvements [2]. - Future applications of supercritical carbon dioxide technology are expected to integrate with various heat sources, enhancing its potential in solar thermal power, waste heat power, and energy storage systems, thereby supporting carbon neutrality goals [3].
