Hydrogen-natural gas blends reduce CO2 emissions by 187.5 kg per ton of fuel with each 10% increase in hydrogen content.
Air and fuel requirements decrease by 15%, while energy efficiency improves by 27.21% for certain blend compositions.
Energetic, exergetic, and exergoeconomic analyses evaluate the performance of gas turbine compression systems with varying hydrogen blends.
Pure hydrogen results in specific gas costs rising to $20.56 per GJ, emphasizing cost implications despite CO2 emission benefits.
