선박의 탄소 포집, 저장, 활용 기술의 특허 동향 분석

As the seriousness of the climate crisis has emerged, technological development is accelerating with the aim of carbon reduction in all industrial sectors. Among them, Carbon Capture, Utilization, and Storage (CCUS) technology is of particular interest, and it is important to understand CCUS technologyused in the shipping field, which provides essential transportation at low cost. Therefore, this paper investigated trends in patent applications by country, technology, and major applicants of ship CCUS technologyand tried to grasp trends in collection / preservation / transportation / utilization technologies through in-depth analysis. To this end, domestic and foreign patents for “ship CCUS” filed by July 2023 were analyzed and 43 core patents were selected to examine the development flow of each technology. Patents related to collection technology were most common, with carbon dioxide-absorbing substances predicted to continue to be developed. In the case of transportation and storage technology, technology development is using a combination of various strategies (capture+storage, capture+transport+storage, etc.) rather than focusing on one technology. Through this paper, we expect to understand the current status of CCUS technologymore comprehensively and use it as a reference for research and development and planning to improve future market competitiveness.
