中国南部の高排出・高経済密度地域を対象に、海洋CCUSの段階的展開フレームワークを開発。地質制約とGISネットワーク最適化を統合した二段階数理モデルを用い、23都市の排出インベントリと海洋貯留ポテンシャルを評価。中程度の炭素価格シナリオ下では、2037年頃に年間純利益が正になり、2040年までにほぼ全ブロックが収益化可能と示唆。
English
This study develops a phased deployment framework for offshore CCUS in southern China, using a two-stage optimization model that integrates geological constraints and GIS network optimization. Analyzing emissions from 23 cities and offshore storage potential, it finds that under a medium carbon-price scenario, projects can achieve positive annual net benefits around 2037, with nearly all blocks profitable before 2040. Transportation distance is identified as a key cost driver.

📄 Abstract（原文）
High-emission, high-economic-density coastal regions require viable pathways to reach net-zero carbon dioxide emissions. Here we develop a phased deployment framework for offshore carbon capture, utilization and storage in southern China. Using a two-stage numerical optimization model integrating geological constraints with geographic information systems-based network optimization, we assess a 2023 emissions inventory from 23 cities compiled from public statistical yearbooks and offshore storage potential. Techno-economic analysis shows that under a medium carbon-price scenario, offshore carbon capture, utilization and storage projects can achieve positive annual net benefits around 2037, and nearly all blocks are expected to turn annually profitable before 2040. Offshore carbon capture, utilization and storage can support coastal regions with high economic density in taking on a larger share of emission reductions. Attention should be paid to optimizing transportation distances. This work provides a replicable planning paradigm for coastal regions to assume greater emission-reduction responsibilities and meet climate targets. Offshore carbon capture projects in southern China can break even before 2040, with transport distance as a key driver. These insights are based on geological assessment, phased planning, and technoeconomic analysis and GIS spatial analysis.
