本レビューは、深部塩水帯水層におけるCO2貯留の最新研究を、実験・シミュレーション・孔隙スケール解析・現場適用の観点から体系的に整理した。構造・残留・溶解・鉱物トラッピングの各メカニズムと貯留効率・圧入性・長期封じ込めに影響する要因を評価し、CO2フォームによる掃攻効率改善や微生物プロセス、塩析出対策など従来レビューで扱われてこなかった論点を掘り下げている。孔隙スケールから現場スケールまでを統合し、安全で拡張可能な気候緩和技術としての帯水層貯留の課題と研究ギャップを示す。
English
This review systematically synthesizes recent advances in CO2 sequestration in deep saline aquifers across experiments, simulations, pore-scale analyses, and field applications. It evaluates trapping mechanisms (structural, residual, solubility, mineral) and factors affecting storage efficiency, injectivity, and long-term containment, while highlighting under-covered topics such as CO2 foams, microbial processes, mechanical integrity, and salt precipitation. By integrating pore-scale to field-scale insights, it offers a multidisciplinary framework for advancing aquifer-based CO2 storage as a scalable climate mitigation technology.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はCCS/CCUSをGX推進の重点技術と位置づけ、北海道・新潟などで実証・商業化を進めている。本レビューは圧入性維持や塩析出対策、長期封じ込め評価といった実務課題を整理しており、国内CCS事業のリスク評価や規制設計、JCMを通じた海外貯留適地開発の検討に資する。
In the global GX context
As CCUS scales under net-zero pathways and Article 6/JCM cooperation, this review consolidates the technical evidence base for saline-aquifer storage—trapping mechanisms, injectivity, and containment security—that underpins MRV and disclosure of carbon removal/storage. It is relevant to global climate policy and transition finance where credible geological storage is a prerequisite for CCS-based mitigation claims.

📄 Abstract（原文）
Deep saline aquifers represents one of the most geologically promising solutions for large-scale carbon dioxide (CO 2 ) sequestration, boasting a global storage potential of up to 10,000 Gt of CO 2 , which far exceeds other subsurface options. This comprehensive review systematically examines recent advancements in aquifers-based CO 2 sequestration through experimental studies, simulations, pore-scale analyses, and field applications. Major trapping mechanisms, including structural, residual, solubility, and mineral trapping, are critically evaluated together with key factors affecting storage efficiency, injectivity, and long-term containment security. This study highlights the potential of CO 2 foams for enhancing storage efficiency through improved mobility control and sweep efficiency within saline aquifers as overlooked by previous reviews. Additionally, it provides a detailed pore-scale analysis of CO 2 -brine-rock interactions, providing new insights into multiphase flow dynamics and trapping mechanisms at the microscopic level, which are crucial for accurate reservoir-scale predictions. Moreover, it explore the emerging role of microbial processes in CO 2 sequestration, including their impact on mineralization and the security of long-term storage through biogeochemical interactions. In addition, the mechanical integrity of saline aquifers during CO 2 injections was discussed in details as not discussed in previous reviews. A dedicated discussion of salt precipitation is presented, including deposition stages, influencing factors such as brine chemistry and injection conditions, and mitigation strategies for maintaining injectivity. The review also identifies key challenges and research gaps for futures researches related to long-term storage prediction, coupled process modeling, and economic feasibility. By integrating insights from pore-scale mechanisms to field-scale applications, this work provides a multidisciplinary framework for advancing aquifers-based CO 2 sequestration as a safe and scalable climate mitigation technology.
