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," marks a significant advancement in transitioning supercritical carbon dioxide power generation technology from laboratory to commercial application [1]. 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 compared to traditional steam generation methods [3][4]. - The supercritical carbon dioxide power generation process involves four steps: compression, heating, expansion, and cooling, which enhances energy efficiency [4]. Group 2: Efficiency and Output - The efficiency of "Super Carbon No. 1" can improve by over 85% compared to existing sintering waste heat steam power generation technologies, resulting in an additional annual electricity output of over 70 million kilowatt-hours [4]. 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 [5]. - The technology has broad application prospects 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 [6]. - Supercritical carbon dioxide technology can effectively utilize industrial waste heat, contributing to energy conservation and carbon reduction efforts in traditional industries like steel and cement [6].
