近年来,储热技术被广泛认为是实现碳中和、碳达峰的一项关键技术备受关注.通过从CNKI、Web of Science等数据库中筛选储热技术相关文献,运用CiteSpace软件进行知识映射,展开系统分析、统计及可视化,绘制出储热技术研究力量合作网络图谱,展示该技术研究力量的分布与科研合作情况.同时针对关键词进行分析,总结储热技术的研究热点、研究前沿及发展趋势,指出相变储热和混合储热模式是未来研究的重点.针对储热材料稳定性差、使用寿命短,有机相变材料成本高、安全性低,系统设备初始造价高、成本回收期长等储热技术现存问题,从政策干预和市场需求角度提出了改进建议.
Research prospect of heat storage technology
In recent years,heat storage technology has been widely considered as a key technology to achieve carbon neutrality and car-bon peaking.By selecting relevant literature on heat storage technology from databases such as CNKI and Web of Science,using CiteSpace software for knowledge mapping,conducting systematic analysis,statistics,and visualization,and a network graph of coopera-tion in heat storage technology research forces was drawn,showcasing the distribution and scientific research cooperation of the technolo-gy research forces.At the same time,analyze the keywords,summarize the research hotspots,frontiers,and development trends of thermal storage technology,and point out that phase change thermal storage and hybrid thermal storage modes are the focus of future research.Considering the existing problems of thermal storage technology,such as poor stability,short service life,high cost and low safety of or-ganic phase change materials,high initial cost of system equipment,and long cost recovery period,improvement suggestions from the perspective of policy intervention and market demand were proposed.
