本レビューは、CCUSを統合的な炭素管理戦略として概観する。溶媒吸収などの成熟技術に加え、MOF・ゼオライト等の新規材料、燃料・化学品・建材への利用、地質・鉱物貯留を整理。セメント・鉄鋼・化学・水素など脱炭素困難セクターの排出削減に寄与する一方、高資本費・エネルギー penalty・輸送インフラ・規制・社会的受容が障壁だと指摘する。
English
This review surveys CCUS as an integrated carbon-management strategy, covering mature solvent absorption alongside emerging materials (MOFs, zeolites), utilization routes (fuels, chemicals, construction materials) and geological/mineral storage. It highlights CCUS's role in hard-to-abate sectors like cement, steel, chemicals and hydrogen, while noting barriers: high capex, energy penalties, transport infrastructure, regulation and public acceptance.

📝 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CCUSを重点技術に位置づけ、製鉄・セメント・化学など素材産業の脱炭素と水素製造の基盤として期待する。本レビューは技術選択肢と貯留・規制課題を整理し、国内実装やSSBJ開示における削減技術の位置づけを検討する材料となる。
In the global GX context
Globally, CCUS is central to net-zero pathways and transition finance for hard-to-abate industry, and increasingly appears in ISSB/CSRD climate disclosures as a mitigation lever. This review consolidates technology readiness and barriers, useful for assessing credibility of corporate CCUS claims and policy support design.

📄 Abstract（原文）
The increasing concentration of atmospheric carbon dioxide (CO₂) has intensified the need for technological approaches capable of reducing emissions from energy-intensive and difficult-to-decarbonize sectors. Carbon Capture, Utilization and Storage has emerged as an integrated carbon-management strategy that combines the separation of CO₂ from industrial or atmospheric sources with its subsequent utilization or long-term storage. Unlike conventional carbon mitigation approaches that primarily focus on energy efficiency and fuel substitution, CCUS can address both combustion-related and process-related emissions, particularly from cement, steel, chemicals and hydrogen production. The technological chain includes CO₂ capture, purification, compression, transportation, utilization and geological or mineral storage. Conventional solvent absorption remains one of the most mature capture technologies, while adsorption, membranes, cryogenic separation and advanced solid materials are being developed to reduce energy consumption and improve selectivity. Materials such as metal–organic frameworks (MOFs), zeolites, porous organic materials and functionalized adsorbents offer opportunities for next-generation CO₂ separation. Captured CO₂ can be converted into fuels, chemicals, polymers, aggregates and construction materials, although the climate benefit depends strongly on energy requirements, carbon source and the duration of carbon retention. Geological storage in saline formations and depleted hydrocarbon reservoirs provides a route for long-term sequestration, while mineral carbonation offers the possibility of converting CO₂ into stable carbonate minerals. Recent developments indicate increasing global investment and project activity, but high capital requirements, energy penalties, transport infrastructure, storage characterization, monitoring, regulation and public acceptance remain important barriers. This chapter reviews the principal CCUS technologies, emerging materials, utilization routes and storage mechanisms and discusses their role in sustainable carbon management and future low-carbon industrial systems.
