CNNP(SH:601985) DT新材料·2025-12-21 16:05Core Viewpoint - The successful operation of the world's first commercial supercritical carbon dioxide power generation unit, "Super Carbon No. 1," marks a significant milestone 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" utilizes supercritical carbon dioxide as the working fluid, achieving efficient and stable power generation through a closed Brayton cycle [3]. - The technology boasts core advantages such as high efficiency, compact system design, fewer auxiliary systems, and strong mobility, addressing technical bottlenecks in the efficient utilization of medium and high-temperature heat sources for small to medium power scales [3]. - The demonstration project is a collaboration between China Nuclear Power Research and Design Institute, Jinan Steel Group International Engineering Technology Co., Ltd., and Shougang Water City Steel Group, featuring a global first set of 2×15 megawatt supercritical carbon dioxide sintering waste heat power generation [3]. Group 2: Performance Metrics - Compared to existing steam power generation technologies for sintering waste heat, "Super Carbon No. 1" improves power generation efficiency by over 85% and net power output by more than 50% [3]. - The system is simplified, requiring 50% less equipment and space, which enhances operational convenience [3]. Group 3: Research and Development - The China Nuclear Power Research and Design Institute has been researching supercritical carbon dioxide power generation technology since 2009, overcoming key technical challenges related to design, manufacturing, and integration [4]. - The institute has established a research and development system for this technology and completed technical validation, forming a collaborative community with leading domestic enterprises and universities [4]. Group 4: Future Projects - In addition to the demonstration project, China Nuclear Group plans to launch a "molten salt energy storage + supercritical carbon dioxide power generation" demonstration project in 2024, which has been selected as a major technological equipment initiative in the energy sector, with expected completion by 2028 [6].
