Abstract

In 2025, the global energy supply exceeded 600 EJ, and energy-sector CO2 emissions reached 35.8 GtCO2, increasing the importance of carbon capture, utilization, and storage (CCUS) for addressing process and residual emissions in hard-to-abate industries. This review examines full-chain commercialization trends in CCUS, focusing on the carbon capture and storage (CCS) value chain, where demonstration and deployment are most advanced. Analysis of technical reports published by the International Energy Agency Greenhouse Gas R&D Technology Collaboration Programme (IEAGHG) in 2025 and 2026, together with relevant field cases, identified key issues. These include industrial integration, air quality impacts, modularization, transport and storage costs and availability, flow metering, storage-site performance verification, long-term monitoring and liability transfer, market and financing structures, and social acceptance. These findings indicate that CCUS represents a portfolio of technologies suited to selective applications rather than a universal substitute. In Korea, commercialization requires an integrated framework encompassing appraisal drilling, injection demonstrations, domestic and international storage portfolios, transport and storage networks, monitoring, reporting, and verification, life-cycle assessment, long-term liability arrangements, market models, and public trust.

Korea’s CCUS strategy

2025년 세계 총에너지공급은 600 EJ를 초과하고 에너지 부문 CO2 배출량은 358억 tCO2에 이르러, 난감축 산업의 공정배출과 잔여배출을 줄이기 위한 탄소포집·활용·저장(Carbon Capture, Utilization, and Storage, CCUS)의 중요성이 더욱 커졌다. 본 총설은 CCUS의 전주기 상용화 동향을 검토하되, 실증과 상용화가 가장 진전된 포집–수송–저장 중심의 CCS 가치사슬에 초점을 두었다. 2025–2026년 IEAGHG 기술보고서와 현장 사례를 분석한 결과, 주요 쟁점은 산업공정 통합, 대기질 영향, 모듈화, 수송·저장 비용과 가용성, 유량계측, 저장소 성능입증, 장기 모니터링과 책임 이전, 시장·금융 구조 및 사회적 수용성으로 확대되고 있다. 이는 CCUS가 보편적 대체수단이 아니라 난감축 산업에 선별 적용되는 포트폴리오 기술임을 시사한다. 한국은 평가정 시추와 주입 실증, 국내외 저장소 포트폴리오, 수송·저장 네트워크, 모니터링·보고·검증, 전과정평가, 장기책임, 시장모델 및 사회적 신뢰를 통합한 전주기 탄소관리 체계를 구축해야 한다.
