基于专利引用的碳捕获与封存技术发展研究

Research on Carbon Capture and Storage Technology Development Based on Patent Citation

碳捕获与封存(CCS)技术是一项新兴的低碳技术,把握CCS技术的发展过程及发展趋势对于企业研发投资、对于低炭技术相关产业的发展具有重要意义。针对目前这一领域研究的不足,提出了基于专利引用分析方法的研究思路,即选取USPTO专利库,运用专利发展路径识别算法从专利引用的角度,绘制CCS技术发展图,识别CCS主要发展路径;并按不同发展阶段的CCS技术状态截面图分析CCS技术的特征和发展路径。研究发现了CCS领域的主要技术、发展路径特点、发展趋势及热点。

Carbon capture and storage （ CCS ） is an emerging low carbon technology. Grasping the development process and trend of CCS technology has great significance to enterprise R＆D investment and the development of low carbon technology related industries. In view of the present insufficient research in this field, this article puts forward the research ideas based on patent citation analysis approach. The da- tabase of the United States Trademarks Office （ USPTO） is utilized. We draw the CCS development map and identify the main develop- ment paths of CCS by applying the algorithm of patent development path recognition, which is based on patent citation. We also analyze the characteristics and development paths of CCS according to its sectional view in different development stages. This study finds the main technologies, development path characteristics, trends and hotspots in CCS field.
