本論文は、廃坑を利用した圧縮空気エネルギー貯蔵（CAES）システムの脱炭素化ポテンシャルを定量化。直接排出削減、間接排出削減、地中隔離の三重の相乗効果をモデル化し、200MWシステムで年間約13万トンのCO2削減が可能と試算。間接削減が86.2%を占め、スケールアップには技術標準化と政策連携が重要。
English
This paper quantifies the decarbonization potential of compressed air energy storage (CAES) systems using abandoned coal mines. A triple synergistic model of direct, indirect, and sequestration-based emission reductions shows a 200 MW system can reduce ~130,000 tons CO2/year, with 86.2% from indirect reduction. Scaling requires technology standardization, regional clustering, and policy coordination.

📄 Abstract（原文）
This article studies the decarbonization potential and scaling pathways of abandoned coal mine compressed air energy storage (CAES) systems. By constructing a comprehensive quantitative model covering direct emission reduction, indirect emission reduction, and sequestration-based emission reduction, it systematically analyzes the triple synergistic decarbonization mechanisms of zero-carbon operation, grid peak-shaving, and geological sequestration. The study shows that using zero-carbon compression and waste heat recovery technologies can eliminate the gas supplementary combustion in traditional systems to achieve direct emission reduction, enhance the grid’s ability to absorb renewable energy for significant indirect emission reduction benefits, and utilize the renovated mine spaces for CO2 geological sequestration to achieve negative emissions. Typical case analysis indicates that a 200 MW system has an annual decarbonization potential of about 130,000 tons of CO2, with 86.2% contributed by indirect emission reduction, highlighting its core value in replacing high-carbon power sources. The study further proposes a scaling development path centered on technology standardization, regional clustering, and policy coordination, pointing out that by reducing costs and improving efficiency of key equipment, establishing mine area storage clusters and coordinated grid dispatch, and innovating carbon markets and green finance mechanisms, abandoned coal mine CAES systems can become a key technology to support the new power system and achieve carbon neutrality goals.
