本研究はインドネシアの石炭火力発電所へのCCS導入の経済的実現可能性を分析。330MW×3基のモデルプラントで、CCS導入によりLCOEは124USD/MWhに上昇。炭素税76USD/tCO2や国際炭素市場価格75USD/tCO2で採算が取れ、中古プラントへの適用が有望。ジャワ・バリ系統では再生可能エネルギーへの移行に至る過渡的戦略としてCCSが有効。
English
This study evaluates retrofitting CCS in Indonesian coal-fired power plants. For a 3x330 MW plant, LCoE rises to 124 USD/MWh. CCS becomes viable with a carbon tax of 76 USD/tCO2 or carbon market revenue of 75 USD/tCO2. Mid-aged plants are most suitable. In the Java-Bali grid, CCS serves as a transition pathway until PV+BESS LCoE falls below 50 USD/MWh.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
インドネシアは日本のGX政策と関連が薄いが、CCS技術の経済性評価やカーボンプライシングの感度分析は日本でも参考になる。日本は石炭火力のフェードアウトが課題であり、CCS導入条件の比較材料となる。
In the global GX context
This paper provides a detailed techno-economic assessment of CCS retrofitting in a developing country context, with sensitivity to carbon pricing and capital grants. It offers insights for countries with existing coal fleets, adding to global CCS literature.
👥 読者別の含意
🔬研究者:The sensitivity analysis and cost breakdown provide a replicable framework for CCS economic modeling in coal-heavy grids.
🏢実務担当者:Utilities and project developers can use the CCS viability thresholds (carbon tax, carbon price, CAPEX grants) for planning.
🏛政策担当者:Policymakers in coal-dependent regions can reference the carbon price and grid integration conditions to design CCS deployment incentives.
📄 Abstract（原文）
This study aims to evaluate impact of retrofitting carbon capture and storage (CCS) technology on coal fired power plants (CFPP) in Indonesia. Using a representative 3×330 MW CFPP, the integration of CCS increases the levelized cost of electricity (LCoE) to 124 USD/MWh. Key cost components include CO₂ capture (21.7%), energy penalty from steam extraction (18.5%), and CO₂ transport and injection (16.7%). Sensitivity analysis indicates that CCS becomes financially viable under a high carbon cap (0.9 tCO₂/MWh) and a carbon tax of 76 USD/tCO₂. Meanwhile, International carbon markets offer a potential revenue at 75 USD/tCO₂ can fully offset CCS costs. Additionally, CAPEX grants can reduce LCoE to 12.4%, serving to mitigate upfront investment for CCS deployment. Within the Java-Bali grid, CFPP account for 58.8% of the generation mix with 41% aged 10-20 years using predominantly subcritical technology while 28% are over 20 years old and follow natural retirement being replaced by renewable energy. CCS retrofitting is more economically and technically viable for mid aged plants with newer technologies and lower emission intensities, supporting grid stability with limited renewable base load availability. This strategy also serves as a transitional pathway toward long term renewable integration until the LCoE of PV+BESS falls below 50 USD/MWh.
