本研究は、水素と天然ガスの混焼をガスタービン燃焼器で数値的に調査した。水素質量分率0%から20%まで変化させ、燃焼挙動、排出、経済性を評価。CO2排出は最大36%削減されるが、NOxは41%増加。燃料コストは最大1.65倍になるが、炭素クレジットにより1.50倍に抑制される。水素混焼の技術的実現可能性と経済的含意を示した。

English

This numerical study investigates hydrogen-natural gas co-firing in an F4-class gas turbine combustor. Hydrogen mass fractions up to 20% reduce CO2 emissions by up to 36% but increase NOx by 41%. Fuel costs rise up to 1.65 times, mitigated to 1.50 times with carbon credits. The findings demonstrate technical feasibility and economic implications of hydrogen co-firing as a transitional decarbonization strategy.

🔬研究者:This study provides a validated numerical model for hydrogen co-firing, offering insights into flame structure changes and emission profiles that can inform future experimental and simulation work.

🏢実務担当者:Power plant operators can use these findings to assess the feasibility of hydrogen co-firing, including emission control strategies and cost implications with carbon credits.

🏛政策担当者:Policymakers can note the potential of hydrogen co-firing to reduce CO2 emissions in gas turbines, but also the need to manage NOx increases and support carbon pricing mechanisms.

📄 Abstract（原文）

The decarbonization of gas turbine power plants is essential in the energy transition, particularly in countries such as Indonesia, where gas turbines play a critical role in supporting the intermittency of renewable energy sources. This study presents a numerical investigation of hydrogen-natural gas co-firing in an F4-class gas turbine combustor using a three-dimensional model reconstructed from high-resolution scanning data. Simulations were performed with hydrogen mass fractions ranging from 0% to 20%, while maintaining a constant turbine inlet temperature to evaluate changes in combustion behavior, emissions, and economic performance. The results show that increasing hydrogen content modifies the flame structure and alters the outlet velocity distribution due to changes in air fuel ratio. Carbon dioxide emissions decrease by up to 36%, while nitrogen oxides emissions increase by 41%, reflecting the higher reactivity and flame temperature of hydrogen combustion. From an economic perspective, hydrogen utilization increases fuel cost by up to 1.65 times compared to natural gas operation. However, the inclusion of carbon credit mechanisms reduces this increase to 1.50 times. These findings demonstrate the technical feasibility and economic implications of hydrogen co-firing as a transitional strategy for decarbonizing gas turbine systems.
