二氧化碳能用来发电了！“超碳一号”示范工程在贵州六盘水首钢水城钢铁厂成功投运

Core Viewpoint - The successful operation of the world's first commercial supercritical carbon dioxide power generation unit, "Super Carbon No. 1," marks a significant advancement in the commercialization of supercritical carbon dioxide power generation technology, transitioning from laboratory to practical application [2]. Group 1: Technology Overview - "Super Carbon No. 1" generates electricity by heating and pressurizing liquid carbon dioxide to a supercritical state, which allows it to store more energy and reduces flow resistance, leading to a simpler and faster response process compared to traditional steam generation methods [4][6]. - The supercritical carbon dioxide power generation process consists of four steps: compression, heating, expansion, and cooling, which collectively create a high-temperature, high-pressure environment to enhance internal energy [6]. Group 2: Efficiency and Output - Compared to existing sintering waste heat steam power generation technology, "Super Carbon No. 1" can improve power generation efficiency by over 85%, resulting in an additional annual output of more than 70 million kilowatt-hours [7]. Group 3: Future Applications - A new energy storage and power generation demonstration project combining molten salt storage and supercritical carbon dioxide power generation is expected to commence construction in Xinjiang in the first half of 2026, utilizing surplus wind and solar power [8]. - The supercritical carbon dioxide power generation technology has promising applications in offshore oil and gas drilling platforms and large vessels, offering advantages such as high efficiency, compact systems, fewer auxiliary systems, and a 50% reduction in space requirements [8]. - The technology is positioned to play a crucial role in energy conservation and carbon reduction efforts in traditional industries like steel and cement, which are significant energy consumers and carbon emitters [8].
