南アフリカの主要堆積盆における地質的CO2貯留ポテンシャルを系統的にレビューした研究。理論貯留容量は150ギガトンと大きく、その大半は海域に分布する。一方でインフラ・資金・規制・ステークホルダー支持・技術面の障壁が実装を妨げており、詳細な地質特性評価と関係者関与の必要性を指摘する。
English
This review evaluates geologic CO2 storage potential across South Africa's major sedimentary basins. It finds a theoretical storage capacity of ~150 gigatons, almost entirely offshore, but identifies infrastructure, finance, regulatory, stakeholder, and technical barriers to implementation. Detailed geological characterization and multi-stakeholder engagement are needed to assess realistic storage potential.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はCCS事業化を法制・ロードマップで推進しており、石炭依存国が抱える資金・規制・社会的受容性の障壁分析は、日本のCCS事業環境整備や資源外交の参考になる。
In the global GX context
As CCUS gains traction in global net-zero pathways and transition finance, this South African case illustrates the gap between theoretical storage capacity and bankable projects—relevant to how disclosure frameworks and climate finance treat CCUS in emerging economies.

📄 Abstract（原文）
Abstract Carbon dioxide (CO 2 ) emissions from fossil fuels and industry in South Africa amounted to 401.89 million tonnes in 2023, with implications for climate change and global warming. South Africa has committed to achieving net-zero carbon emissions by the year 2050. However, the transition to a low-carbon economy must be pursued sustainably and equitably, given South Africa’s reliance on coal and its status as a leading global coal producer. This highlights the potential of CCUS (carbon capture, utilisation, and storage) as a reliable solution for achieving a low-carbon economy. This study adopts a comprehensive and systematic review approach to identify potential opportunities, constraints, and future directions for geologic carbon capture and storage. This requires reviewing and evaluating relevant prior work conducted in various sedimentary basins across South Africa. These findings indicate that South Africa has significant potential for the sequestration of CO 2 in geologic formations, with a theoretical storage capacity of 150 gigatons, almost entirely offshore. However, there are impediments to putting a geologic carbon storage project into action. This includes but is not limited to infrastructure, financial issues, a lack of stakeholder support, regulatory restrictions, and technical difficulties. Significant work will be needed to evaluate realistic CO 2 storage potential, which will include detailed geological characterization: geophysics, petrophysics, geomechanics, geochemistry, sedimentology, and dynamic modelling of CO 2 sequestration. Furthermore, the engagement of policymakers, societal opinion shapers, and oil industry professionals, among many others, may help build stakeholder support.
