Abstract

CO2 storage is a very important technology for reduction of greenhouse gas emissions and has been considered as almost the only viable and effective option for immediate large-scale CO2 sequestration. Small-scale demonstration project for offshore CO2 storage in the Pohang Basin is the transitional stage R&D program for technological preparation of large-scale CO2 storage project in Korea. Through the extensive exploration research for prospective CO2 storage sites, the offshore strata in the Pohang Basin was recommended for the storage formation of the small-scale demonstration project. The Pohang Offshore Storage Project launched at 2013, and has accomplished the technical demonstration and technological independence in a wide range of CO2 storage technology, such as geophysical exploration, storage site characterization, storage design, offshore platform construction, injection-well drilling and completion, deployment of injection facility, operation of CO2 injection, and CO2 monitoring. The project successfully carried out CO2 test injection in early 2017, and achieved its final goal for technical development and demonstration of CO2 storage in Korea. The realization of CO2 injection in this project is the measurable result and has been recorded as the first success in Korea. The Pohang Offshore Storage Project has a future plan for the continuous operation of CO2 injection and completion of CO2 monitoring system. The project has provided in-house technical and practical expertises, which will be a solid foundation for the commercial-scale CO2 storage business in Korea. Additionally, the project will help to secure national technical competitiveness in growing international technology market for CO2 storage.

신기후체제 출범 이후 온실가스 감축목표 달성을 위한 대규모 CO2 직접 감축의 거의 유일한 방안으로 알려져 있는 대용량 CO2 지중저장의 중요성이 강조되고 있다. 포항 분지 해상 중소규모 CO2 지중저장 실증사업은 대규모 CO2 저장 사업에 필요한 핵심 기술을 우선적으로 확보하기 위해 추진하고 있는 연구개발 사업이다. 국내 저장 실증을 위한 CO2 저장소 확보를 위해 2010년부터 3년간 육상-연안 CO2 저장소 탐사 연구 과제를 수행하여, 한반도 동남부 육상 및 연안에 걸쳐 발달하고 있는 포항분지를 중소규모 CO2 지중저장 실증 후보지역으로 선정한 바 있다. 2013년부터는 포항분지 해상 지층을 대상으로 저장소 탐사, 탐사시추, 저장소 특성화, 저장 설계, 플랫폼 설계 및 설치, 주입공 시추 및 완결, 주입설비 설치, 주입 및 모니터링 등의 개별 기술 개발을 수행하였으며, 2017년 초 국내 기술력을 기반으로 해저 실증 저장소에 국내 최초로 CO2 시험주입 실증에 성공하였다. 향후에는 CO2 저장소 연속 운전 실증을 위한 수송체계 구축과 저장소 운영체계 확립 연구를 진행할 계획이다. 안전하고 효율적인 저장소 운영을 위해 상시 주입 모니터링 및 정기적인 거동 · 누출 · 환경 모니터링을 수행할 계획이며, 이를 위한 주입 전 모니터링을 완수하고 모니터링 체계를 구축하였다. 포항분지 해상 중소규모 CO2 지중저장 실증 연구를 통해 국내 대규모 CCS 통합실증 및 상용화 사업에 필요한 핵심적 CO2 저장 기술을 자립화 하였고, 성공적인 시험 주입으로 대규모 CO2 지중저장 사업의 기술적·경험적 기초를 확보하였다. 또한 본 연구 사업은 국제적으로 점차 확대되고 있는 CO2 지중저장 기술 시장에서 우리나라의 기술 경쟁력을 확보하는데 기여할 것으로 기대된다.
