Abstract
우리나라는 2030년 국가 온실가스 감축목표 (NDC) 달성을 위해 부문별 감축 목표치를 제시하고 있으며, 특히 CCUS 분야에서 1,120만톤의 감축 목표를 설정하였다. 그러나 실제 목표 달성을 위한 세부 이행 경로에 대한 정량적 분석은 부족한 실정이다. 이 연구에서는 CCUS 분야의 CO2 감축경로를 추정하기 위한 체계적인 방법론을 개발하고, 개발한 방법론과 임의의 데이터를 활용하여 사례 연구를 수행하였다 . 먼저 연도별 CCUS 관련 예상 사건들을 수집하고 정량화하여 마스터데이터를 구성한 후, 이를 기반으로 감축경로를 추정하는 상향식 (bottom-up) 방법을 제안하였다. 마스터 데이터는 엑셀 기반의 데이터베이스로 구축하였으며, 파이썬 기반의 분석 툴을 개발하여 데이터 처리 및 시각화를 수행하였다 . 개발된 방법론을 통해 년도별, 포집원별, 처리방안별 CO2 흐름을 정량적으로 분석하고, 시나리오별 감축경로를 도출할 수 있다 .
South Korea has set sector-specific reduction targets to achieve its 2030 Nationally Determined Contribution (NDC), including a reduction target of 11.2 Mt-CO2 in the CCUS sector. However, the quantitative analysis of detailed implementation pathways to achieve these targets remains insufficient. This study develops a systematic methodology for estimating CO2 reduction pathways in the CCUS sector and presents case studies using the developed methodology and arbitrary data. We propose a bottom-up approach that creates master data by collecting and quantifying the expected CCUS-related events by year and estimates reduction pathways based on this data. The master data was constructed as an Excel-based database, and a Python-based analysis tool was developed for data processing and visualization. Through the developed methodology, we were able to quantitatively analyze CO2 flows by capture sources and treatment methods, and derive reduction pathways by scenarios.
