本研究は、イラク・バグダッドの大規模ガス複合サイクル発電所（Bismayah）を対象に、90%のCO2回収率を持つアミン吸収型炭素回収ユニットの設計と性能評価を行った。回収ユニット導入により発電効率が14%、正味出力が13.6%低下する一方、排出原単位は376.85 gCO2/kWhから40.6 gCO2/kWhへ大幅に改善されることを示した。
English
This study evaluates a post-combustion amine-based carbon capture unit (90% capture efficiency) for a 4500 MW gas combined cycle plant in Baghdad, Iraq. It finds a 14% efficiency penalty and 13.6% net power reduction, but specific emissions drop from 376.85 to 40.6 g CO2/kWh, demonstrating trade-offs between capture and performance.

日本のGX文脈において
本論文は特定の発電所を対象としているが、CCUS導入時の効率低下やコスト増大という現実的な課題を示しており、日本の水素・アンモニア混焼やCCS戦略にも示唆を与える。日本は2030年までにCCS/CCUSの商用化を目指しており、実証データとして参考になる。
In the global GX context
While focused on an Iraqi plant, this paper provides empirical data on the efficiency penalty (14%) and emission reduction potential of post-combustion carbon capture, informing global CCS cost-benefit assessments. Such trade-off analyses are critical for ISSB and transition finance disclosures requiring physical decarbonization pathways.

📄 Abstract（原文）
The study of carbon dioxide capture systems arises from increasing concerns about global greenhouse gas emissions as an effective way to mitigate Climate Change. This study analyses the removal of carbon dioxide (CO2) from the Power Plant (Bismayah) in Baghdad, Iraq. It comprises six stages; each stage produces 750 MW, a total power generation of 4500 MW, and operates on a natural gas combined cycle system. The effect of carbon capture on the efficiency and power generation of the plant is also being studied. The post-combustion method, which depends on the absorption and adsorption units of amines, is considered one of the most widely used methods due to its high efficiency in carbon capture. The study was conducted using the Thermo-flow and Aspen HYSYS 14 software®. The study concluded that the amount of carbon dioxide released to the ocean from the plant has an average value of 2.26 (Mt CO2/yr) from each stage. The total released CO2 quantity can be estimated as approximately 14 Mt CO2/yr. However, adding a carbon capture unit with a capture efficiency of 90 % will reduce the electricity production efficiency of the combined cycle by 14% and the net power decrease by 13.6%. However, the benefit of the applied procedure is that annual carbon dioxide concentration per unit will decrease to 0.226 (Mt CO2). The respective specific emissions per produced electricity with and without carbon capture are 40.6 g CO2 / kWh and 376.85 g CO2/kWh.
