本研究は、中国のセメント産業を対象に、2025年から2060年までの省レベルでの脱炭素経路を最適化する全体的システムモデルを開発。地域ごとに最適な技術組み合わせが異なり、2050年までは従来プロセス+ CCSが主流だが、2060年のカーボンニュートラル達成にはグリーン水素を用いた新規化学プロセスへの移行が必要。この最適化により、単位クリンカーコストを2025年比で約58%削減可能。
English
This study develops a whole-systems optimization model for provincial-scale decarbonization pathways of China's cement industry from 2025 to 2060. Results show significant spatial and temporal heterogeneity: before 2050, traditional cement processes with CCS dominate, while achieving carbon neutrality by 2060 requires a shift to novel chemical processes using green hydrogen. The optimized pathway reduces unit clinker costs by approximately 58% compared to 2025 levels, meeting the 2060 carbon neutrality target.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国のセメント産業は世界生産の半分以上を占め、脱炭素は地球規模の課題。日本のセメント業界も同様の構造問題を抱え、地域最適化のフレームワークは参考になる。ただし、中国特有の資源・価格条件を前提としており、直接適用には調整が必要。
In the global GX context
China's cement sector accounts for over half of global production and 8% of global CO2 emissions, making its decarbonization critical worldwide. This model provides a template for regionally optimized industrial decarbonization, showcasing the interplay of CCS and green hydrogen. The framework offers quantitative support for policymakers globally to design cost-effective, province-specific strategies.

📄 Abstract（原文）
China's cement industry accounts for over half of global production and contributes 8% of global CO2 emissions, making its decarbonization critical for achieving climate targets. While carbon capture and storage (CCS) and carbon capture and utilization (CCU) are essential deep decarbonization technologies, existing research has not adequately addressed the regional and temporal variations needed for optimal pathway selection across China's diverse provinces. This study develops a comprehensive whole-systems optimization model to design provincial-scale decarbonization pathways for China's cement industry from 2025 to 2060. The model reveals significant spatial and temporal heterogeneity in optimal technology combinations. Before 2050, traditional cement processes integrated with CCS (TCP-CCS) represent the dominant bridging technology for low-carbon transition. However, reaching carbon neutrality by 2060 necessitates an eventual shift toward widespread deployment of novel chemical processes combined with green hydrogen (NCP-H2) as the ultimate decarbonization pathway. Notably, regional natural gas prices significantly affect technology feasibility and deployment timing. The optimized transition pathway reduces unit clinker costs by approximately 58% compared to 2025 levels while successfully meeting the 2060 carbon neutrality target. This research framework provides quantitative decision support for policymakers to design cost-effective, province-specific decarbonization strategies that align with local resource endowments and economic conditions, ultimately advancing deep decarbonization across China's industrial sector.
