CCSはネットゼロ達成の鍵だが、2050年でも世界排出量の約6%にとどまる見通し。回収・輸送・貯留インフラの大規模拡張が必要で、地域ごとに異なる法規制・許認可・責任制度が技術設計や投資判断に直結する。炭素価格や税額控除、差額契約は追い風となるが、CO2価格の不確実性と長期収益の見通しが事業性の課題となる。
English
CCS is critical for net-zero but is projected to cover only ~6% of global emissions by 2050, requiring massive scale-up of capture, transport, and storage. Regionally diverse legal, permitting, and liability regimes directly shape technical design and investment. Carbon pricing, tax credits, and CfDs help, yet uncertain CO2 prices and long-term revenue clarity still challenge project business cases.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はCCS事業法整備やJOGMEC主導の貯留適地調査を進めており、本稿の許認可・責任・事業性の論点は国内CCS法制度設計や企業の投資判断に直接示唆を与える。
In the global GX context
As ISSB/CSRD push hard-to-abate sectors to disclose transition plans, this paper highlights how permitting, liability, and revenue certainty shape CCS viability—key for global transition-finance and disclosure debates.

📄 Abstract（原文）
Scaling Carbon Capture and Storage (CCS) worldwide is critical for achieving net-zero targets and ensuring clean energy transition. Current development efforts focus on hard-to-abate CO2 emissions from cement, chemical and steel industries. As a bridging technology CCS may also be applied to emissions from combustion processes in regions or periods where renewable energy sources are not yet available. Recent industry outlooks (DNV 2025) indicate that despite economic growth driving global CO2 from approximately 38 GtCO2/yr today to 59 GtCO2/yr in 2050, the contribution of CCS is expected to rise from currently 0,1% to just about 6%. While the share remains limited in relative terms, this represents a massive increase of captured and stored CO2 from ca. 50 MtCO2/yr today towards 1,3 GtCO2/yr. Achieving this scale-up implies a substantial expansion capture facilities, transport infrastructure, and geological storage capacity. CCS deployment takes place within evolving and regionally diverse policy and regulatory frameworks (ERIA 2023; Martinez Castilla et al. 2025; Vishal et al. 2024). Local legal requirements, permitting regimes, and liability arrangements directly influence the technical design, investment decisions, and feasibility of CCS value chains. While policy instruments such as carbon pricing, tax credits, or contracts for difference can provide momentum for infrastructure investment, the business cases of individual CCS projects often remain challenged by uncertain CO2 prices and long-term revenue clarity. In many cases, CCS developments are further interconnected with adjacent value chains such as enhanced oil recovery or blue hydrogen production.
