Abstract
This paper presents a comparative analysis of natural gas and diesel as fuels for gas turbine power generation, focusing on efficiency, emissions, and sustainability. The findings indicate that natural gas, owing to its higher hydrogen-to-carbon ratio, achieves significantly lower NOx and greenhouse gas emissions compared to diesel. However, diesel exhibits slightly superior thermal efficiency and lower specific fuel consumption under similar operational conditions. Overall, the study concludes that natural gas represents a more sustainable and environmentally favorable option, offering a balanced trade-off between performance, cost, and emission reduction in modern energy systems.
