Efficiency optimization model for coal-fired power plants with CCS in emissions trading markets

日本語

本論文は、排出権取引市場のもとでCCS（炭素回収・貯留）を導入した石炭火力発電所の効率最適化モデルを提案する。発電効率とCO2削減コストのトレードオフを分析し、排出権価格が最適なCCS稼働率に与える影響を定量化。日本の石炭火力政策にも示唆を与える。

English

This paper proposes an efficiency optimization model for coal-fired power plants equipped with carbon capture and storage (CCS) operating under emissions trading markets. It analyzes the trade-off between power generation efficiency and CO2 reduction costs, quantifying how carbon prices affect optimal CCS utilization rates. The model provides insights for plant operators and policymakers in carbon-constrained environments.

日本のGX文脈において

日本は石炭火力発電への依存度が高く、CCSはカーボンニュートラル達成の鍵技術とされる。本モデルは、排出権取引（国内・国際）の価格設定がCCS導入判断に与える影響を定量化し、電源構成転換やコスト負担の議論に資する。

In the global GX context

Globally, CCS is critical for decarbonizing hard-to-abate sectors. This model directly addresses how emissions trading market design (e.g., EU ETS, China's national ETS) influences the economic viability of CCS retrofits, providing a tool for investors and regulators to assess policy impacts on power sector emissions.
