In recent years, supercritical CO power cycles have received a large amount of interest due to their exceptional theoretical conversion efficiency above 50%, which is leading a revolution in power cycle research. Furthermore, this high efficiency can be achieved at a moderate temperature level, thus suiting concentrating solar power (CSP) applications, which are seen as a core business within supercritical technologies. In this context, numerous studies have been published, creating the need for a thorough analysis to identify research areas of interest and the main researchers in the field. In this work, a bibliometric analysis of supercritical CO for CSP applications was undertaken considering all indexed publications within the Web of Science between 1990 and 2020. The main researchers and areas of interest were identified through network mapping and text mining techniques, thus providing the reader with an unbiased overview of sCO research activities. The results of the review were compared with the most recent research projects and programs on sCO for CSP applications. It was found that popular research areas in this topic are related to optimization and thermodynamics analysis, which reflects the significance of power cycle configuration and working conditions. Growing interest in medium temperature applications and the design of sCO heat exchangers was also identified through density visualization maps and confirmed by a review of research projects.
近年来，超临界二氧化碳动力循环因其超过50%的卓越理论转换效率而备受关注，这正引领着动力循环研究的一场革命。此外，这种高效率可以在适度的温度水平下实现，因此适合聚光太阳能发电（CSP）应用，而聚光太阳能发电被视为超临界技术的核心业务。在此背景下，已经发表了大量研究，因此需要进行全面分析，以确定该领域的研究热点和主要研究人员。在这项工作中，对1990年至2020年间科学网中所有索引出版物进行了关于用于聚光太阳能发电应用的超临界二氧化碳的文献计量分析。通过网络映射和文本挖掘技术确定了主要研究人员和研究热点，从而为读者提供了超临界二氧化碳研究活动的客观概述。将综述结果与最近关于用于聚光太阳能发电应用的超临界二氧化碳的研究项目和计划进行了比较。结果发现，该主题中热门的研究领域与优化和热力学分析相关，这反映了动力循环配置和工作条件的重要性。通过密度可视化图还发现了对中温应用和超临界二氧化碳热交换器设计的兴趣日益浓厚，并通过对研究项目的综述得到了证实。
