이산화탄소 포집/활용/저장 : CCUS 기술 현황 리뷰, 예측과 분석
Carbon Capture, Utilization, and Sequestration: Review of the State of CCUS Technologies - Forecast and Analysis
이산화탄소 포집/활용/저장(CCUS)은 유엔의 기후변화에 관한 정부간 패널이 나타내 보인 모든 경로를 포함한 탈탄소화 전략에서 필수적인 요소로 인식되고 있습니다. 시멘트 제조나 제철 등 탈탄소화가 어려운 고배출량 업계에서 이산화탄소 포집/활용/저장(CCUS)은 배출량을 감축하기 위한 유일한 효과적인 옵션 중 하나입니다.

Carbon capture, utilization, and sequestration (CCUS) has increasingly been recognized as an essential component of decarbonization strategies including all pathways outlined by the United Nation's Intergovernmental Panel on Climate Change. In heavy-emitting industries that are difficult to decarbonize, such as cement making and steel making, CCUS stands out as one of the only viable options to mitigate emissions. However, existing capacity, announced new projects, and investment spending in recent years have been far less than what is needed for the rapid global deployment of CCUS capacity that is necessary to achieve net-zero global CO2 emissions by 2050.
High project costs predominantly stem from expensive CO2 capture equipment and are one of the primary obstacles to the successful scaleup of CCUS capacity. Therefore, government support through grants and tax incentives is key to averting first-mover disadvantages and enabling further CCUS research, development, and deployment. While learning rates have cut costs since the first CCUS project went online 50 years ago, a much steadier and more robust queue of projects is needed for economies of scale to further reduce expenses. In the meantime, several companies-many from the oil & gas industry-have partnered in recent years to share knowledge and explore opportunities in CCUS. These relationships, along with dozens of proposed CCUS hubs around the world, could cut costs further.
This Guidehouse Insights report provides capacity and spending forecasts for four carbon capture technology stages: pre-combustion, post-combustion, oxy-fuel combustion, and direct air capture. Forecasts are provided for major global regions and cover 2022-2031.
