Özet
Increasing environmental problems have heightened the need for sustainable energy solutions, and H2 has emerged as a promising option for reducing carbon emissions in dual-fuel engines. Using H2 alongside traditional aviation fuels offers a cleaner option. In this study, the dual-fuel behavior of a micro gas turbine operating with H2 addition using JET A1, FAME, and Eurodiesel fuels was experimentally investigated. In the experiments, H2 was injected into the engine at flow rates varying between 0 and 200 L min−1. Experiments were conducted at speeds of 60,000, 80,000, and 100,000 rpm, and the results were evaluated in terms of engine performance, combustion efficiency, emissions, acoustic characteristics, and environmental impact. The findings showed that the engine behavior during dual-fuel operation changed significantly as the amount of H2 increased. Liquid fuel consumption decreased by up to 43.6 %, and significant reductions in carbon-based emissions were achieved, especially at low speeds. CO values for JET A-1 decreased from 0.08 to 0.03 vol%, and CO2 values decreased from 0.99 to 0.51 vol%. In addition, specific energy consumption decreased by approximately 8 %, while thrust and power output increased by 13.3 % and 28.9 %, respectively. While JET A-1 provides the highest efficiency at high speeds, FAME yielded more stable results at low speeds. Additionally, in the assessments conducted for JET A-1, it was determined that the increasing H2 content significantly reduced the environmental and social costs (from 141.28 to 56.00 €.kN−1.h−1).
