本研究は、炭素価格シナリオ下での水素統合コンバインドサイクル発電所の技術経済的最適化フレームワークを提示する。Aspen HYSYSによる熱力学モデルとPSOアルゴリズムを用い、水素混合がタービン出力、効率、CO2排出に与える影響を評価。結果、水素割合増加で出力はほぼ一定（約10.19 MW）、効率は36.56%から37.20%に微増、CO2排出は5,504.94 kg/hからほぼゼロに削減。炭素価格15, 30, 80 USD/tCO2で総運用コストはそれぞれ5,883.60, 9,172.30, 21,768.00 USDと試算。
English
This study presents a techno-economic optimization framework for hydrogen-integrated combined cycle power plants under carbon pricing. Using Aspen HYSYS and Particle Swarm Optimization, it evaluates hydrogen blending effects on turbine output, efficiency, and CO2 emissions. Results show that increasing hydrogen fraction keeps output nearly constant (~10.19 MW), slightly improves efficiency (36.56% to 37.20%), and drastically reduces CO2 emissions (5,504.94 kg/h to near zero). Total operating costs under carbon prices of 15, 30, and 80 USD/tCO2 are 5,883.60, 9,172.30, and 21,768.00 USD, respectively.

📄 Abstract（原文）
This study presents a techno-economic optimization framework for hydrogen-integrated combined cycle power plants operating under various carbon pricing scenarios. A thermodynamic model developed in Aspen HYSYS was used to evaluate the effects of hydrogen blending on turbine power output, cycle efficiency, and CO₂ emissions. The results indicate that, as the hydrogen fraction increases, turbine power output remains nearly constant at around 10.19 MW, while cycle efficiency improves slightly from 36.56% to 37.20%, and CO₂ emissions decrease significantly, from 5,504.94 kg/h to nearly zero. Using the Particle Swarm Optimization (PSO) algorithm, the dispatch problem is solved under carbon prices of 15 USD/tCO₂, 30 USD/tCO₂, and 80 USD/tCO₂, considering fuel, hydrogen, and CO₂ emission costs. Under normal load conditions, total operating costs with hydrogen integration are 5,883.60 USD, 9,172.30 USD, and 21,768.00 USD, respectively.
