本レビューはCCSを回収・輸送・貯留のライフサイクル全体で評価し、GWPやEROI、コスト指標を統合して技術的実現性・環境性能・経済性を比較した。回収技術は成熟しつつあるが貯留は発展途上であり、ハイドレート基盤CCS（HBCC/HBCS）は低コスト・低エネルギー・低GWPの利点を持つが大規模連続運用の成熟度が課題と指摘する。サーキュラーエコノミーとマルチモーダル輸送の統合がCCSネットワークの効率と経済性を高め、NGHからのメタン生産を経済的に可能にし得ると結論づける。
English
This review evaluates CCS across the full life cycle—capture, transport, and sequestration—integrating technical feasibility, environmental performance (GWP, EROI), and cost metrics for onshore and offshore storage. Capture technologies are relatively mature while storage lags; hydrate-based carbon capture (HBCC) offers lower cost, energy use, and GWP but faces maturity and scale-up barriers. Combining HBCC with sequestration, multimodal transport, and circular-economy principles can improve network efficiency and economic viability, potentially enabling economically viable methane production from natural gas hydrates.

日本のGX文脈において
日本はCCSをGX推進法・JCM・アジアCCUSネットワーク構想の中核技術と位置づけ、北海道・マレーシア等での貯留事業を進める。本レビューは回収技術の成熟度と貯留段階のギャップ、HBCCのコスト優位性を示し、国内CCS事業の技術選定やLCA評価、カーボンクレジット設計に示唆を与える。
In the global GX context
CCS is central to global net-zero pathways and increasingly embedded in disclosure and transition-finance frameworks (TCFD/ISSB, EU CRCF, US 45Q). This review's life-cycle and techno-economic synthesis helps investors and standard-setters assess CCS project credibility, storage readiness, and the role of emerging hydrate-based capture in credible decarbonization claims.

📄 Abstract（原文）
Abstract Carbon capture and storage (CCS) plays a critical role in reducing CO2 emissions from industry and the atmosphere, but conventional cost and environmental assessments often overlook impacts across the full life cycle, including capture, transportation, and sequestration. This review provides a comprehensive evaluation of CCS by integrating technical feasibility, environmental performance, and economic factors, including storage scenarios in both onshore and offshore contexts. This study highlights key metrics such as global warming potential (GWP) and energy return on investment (EROI), along with cost estimates to assess overall effectiveness. The study finds that while some carbon capture technologies are already mature and widely deployed, carbon storage remains at earlier stages of development, indicating the need for further advancement to fully utilize CCS’s potential. Gas hydrate-based carbon capture (HBCC) offers advantages in terms of lower cost, reduced energy consumption, and lower carbon footprint (global warming potential, GWP) compared to other capture technologies. However, its widespread adoption is currently limited by lower technological maturity and challenges associated with continuous, large-scale implementation. Integrating HBCC with sequestration and combining multimodal transport systems with circular economy principles can significantly improve the efficiency of the CCS network and, eventually, its economic feasibility. By integrating life-cycle assessment with techno-economic and circular approaches, methane production from natural gas hydrates (NGHs) using hydrate-based carbon sequestration (HBCS) can reduce overall costs while minimizing waste and enhancing resource efficiency. With advancements in sustainable CO2 separation, improved process efficiency, and increased technological maturity, HBCS is becoming more competitive and can enable methane production from NGHs at economically viable costs.
