Energy Performance of Gas Turbine Compressor Stations Operating With Hydrogen–Natural Gas Blends

Year: 2025

Type: article

Abstract: Hydrogen is a rising energy carrier for decarbonization. One possible use is blending it with natural gas, but researchers must address performance issues in thermal systems. In this study, we evaluate the performance of a natural gas compression system with a gas turbine using energetic, exergetic, and exergoeconomic analyses for different hydrogen–natural gas blends. The analyses reveal a reduction of 187.5 kg CO2 per ton of fuel for every 10% increase in hydrogen content. Furthermore, air and fuel requirements decrease by 15%, while compression train energy efficiency improves by 27.21% in certain blends. However, the specific cost of gas rises to $20.56/GJ when using pure hydrogen. Finally, increasing the hydrogen fraction reduces CO2 emissions but also raises costs.
