Abstract
Given the continued climate change and global warming, various technologies for greenhouse gas reduction were discussed worldwide as all 195 countries participated in the Paris Agreement on the reduction of greenhouse gases. The agreement was adopted at the 21st Conference of Parties to the UNFCCC (COP21), which was held in Paris, France, in December 2015, and it revealed that reducing CO2 is the most efficient method of greenhouse gas reduction. Accordingly, carbon capture/utilization/storage (CCUS) technology has been noted as a means of making practical contributions to CO2 reduction, and research and development (R&D) activities in many countries are active in the field of CCUS technology. Therefore, this study aims to provide a basis for CCUS R&D and strategic support measures by analyzing patent trends in technologies related to CCUS. The patent analysis collected a total of 10,137 patents in the United States, Korea, Japan, Europe, and China; the number of patents in the United States was the highest according to patent analysis by country. According to an analysis by technology, capture-related technology was high at 60%, but given the recent increase in technology related to utilization, technology demonstration, R&D, and policy support should be continued.
