CCSの在来型・新興回収技術（燃焼前・燃焼後・酸素燃焼、DAC、MOF、グラフェン膜等）を体系的に整理したレビュー。パイプライン・船舶によるCO₂輸送、帯水層・枯渇油ガス層・玄武岩層への地質貯留、SleipnerやGorgon等の実機事例を比較検討する。資本コスト、エネルギー penalty、規制・社会的受容などの障壁を整理し、産業脱炭素化には他施策との併用と制度・資金支援が不可欠と結論づける。

English

A comprehensive review of conventional and emerging CCS capture methods (pre-/post-combustion, oxy-fuel, DAC, MOFs, graphene membranes) alongside CO2 transport and geological storage options. It compares industrial cases such as Sleipner, Gorgon and Boundary Dam, and assesses cost, energy penalty, regulatory and public-acceptance barriers. CCS is framed as a key lever for hard-to-abate industrial decarbonization when paired with other measures and supportive policy.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本はGX推進戦略でCCSを重点領域と位置づけ、JOGMEC主導の適地調査やCCS事業法整備を進める。本レビューは回収材料・輸送・貯留の技術的制約を俯瞰でき、国内CCS事業のフィージビリティ検討や産業界の脱炭素ロードマップ策定の基礎資料として有用。

In the global GX context

CCS is central to net-zero pathways and increasingly embedded in disclosure and transition-planning frameworks (ISSB, TCFD) as a residual-emissions lever for hard-to-abate sectors. This review offers a consolidated technical baseline for assessing credibility of corporate CCS claims and the infrastructure, cost and regulatory conditions under which they can be delivered.

📄 Abstract（原文）

Abstract Carbon capture and storage (CCS) is an important technology for reducing carbon dioxide (CO₂) emissions from energy generation and industrial processes, particularly in hard-to-abate sectors. This review examines conventional and emerging CCS technologies, their operating principles, performance evaluation, applications, limitations, and contributions to global decarbonization. Conventional capture approaches, including pre-combustion, post-combustion, and oxy-fuel combustion, are discussed alongside emerging technologies such as cryogenic separation, chemical looping, direct air capture (DAC), graphene-based membranes, and metal–organic frameworks (MOFs). Other carbon removal approaches, including bioenergy with carbon capture and storage (BECCS), biochar, and enhanced rock weathering, are also considered. CO₂ transportation by pipeline and ship is reviewed in terms of infrastructure requirements, material compatibility, safety, and economic feasibility. Geological storage options, including deep saline formations, depleted hydrocarbon reservoirs, and suitable basalt formations, are examined with respect to trapping mechanisms, monitoring, containment, and long-term stability. Industrial case studies, including Sleipner, Gorgon, and Boundary Dam, provide insights into practical experience and operational challenges. The review also evaluates economic, environmental, and regulatory barriers to CCS deployment, including capital costs, energy penalties, public acceptance, and lifecycle emissions. Future progress will require affordable and durable capture materials, effective integration with industrial processes, reliable transportation and storage infrastructure, appropriate regulatory frameworks, and supportive financial incentives. Overall, CCS can contribute significantly to industrial decarbonization when implemented alongside other emissions-reduction strategies and supported by robust environmental assessments, effective monitoring, and long-term infrastructure planning.
