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.

지속적인 기후변화와 지구온난화로 인해 2015년 12월 프랑스 파리에서 열린 제21차 유엔기후변화협약(UNFCCC) 당사국총회(COP21)에서 모든 당사국(195개국)이 온실가스 감축에 참여하는 파리협정이 체결됨에 따라 전 세계적으로 온실가스 감축에 대한 다양한 기술이 거론되고 있으며, 그 중에 CO2를 감축시키는 것이 가장 효율적이라고 분석 되었다. 이에 따라 CO2 포집/저장/활용 기술(CCUS)은 CO2 감축의 실질적인 기여를 할 수 있는 수단으로 주목받았으며, CCUS기술 분야에 대해서 많은 국가들의 연구개발 활동이 활발히 이루어지고 있다. 따라서 본 연구에서는 이산화탄소 포집/저장/활용과 관련된 기술의 특허 동향 분석을 통해 CCUS 연구개발 및 전략적 지원방안 수립에 근거를 제시하고자 한다. 특허 분석은 미국, 한국, 일본, 유럽, 중국의 특허를 검색하여 총 10,137건을 수집하였고, 국가별 특허분석 결과 미국의 수가 가장 많았다. 기술별 분석에 따르면 포집에 관한 기술이 60%로 높았지만, 최근에는 활용에 관한 기술이 점점 증가하고 있는 것으로 나타난 만큼 이에 대한 기술 실증과 연구개발 및 정책적 지원이 지속적으로 이루어져야 될 것으로 보인다.
