面对面丨二氧化碳“烧”出高效电 中国团队攻克世界级难题

Core Viewpoint - The article discusses the successful implementation of the world's first commercial supercritical carbon dioxide (sCO2) power generation system, named "Super Carbon No. 1," at the Shougang Steel Plant in Liupanshui, Guizhou, which utilizes sCO2 as a heat transfer medium for efficient power generation [2][30]. Group 1: Technology Overview - The sCO2 power generation technology represents the forefront of 21st-century power generation technology, offering significant advantages over traditional steam turbine systems, including higher efficiency, smaller size, faster response, and environmental benefits [6][12]. - The "Super Carbon No. 1" project has achieved over 85% efficiency improvement and more than 50% increase in net power generation compared to conventional steam power generation systems [12]. Group 2: Development Journey - The development of sCO2 technology began in 2009, with initial research focusing on its potential in power generation, which was previously uncharted [12][14]. - After years of research and overcoming significant challenges, the technology reached the laboratory testing phase in 2016, followed by small-scale power generation validation in 2019, marking a critical breakthrough [20][22][24]. Group 3: Commercialization and Impact - In August 2022, a partnership with Jisco International was established, leading to the construction of the "Super Carbon No. 1" demonstration project, which commenced in late 2023 [28][30]. - The project is expected to generate over 70 million kilowatt-hours of electricity annually, resulting in an additional revenue of nearly 30 million yuan for the company [30].
