Heat transfer performance analysis of hydrogen-ammonia combustion in a micro gas turbine for sustainable energy solutions

This research work investigates the combustion characteristics of hydrogen, ammonia, and hydrogen-ammonia fuel blends in a micro gas turbine through numerical simulations. By employing a transient, pressure-based solver alongside the SST k-omega turbulence model, the aim is to optimize power output while minimizing NOx emissions. The outcomes reveal that hydrogen provides excellent energy efficiency and significant power output. On the other hand, ammonia extends challenges due to its slower flame speed and lower flammability but holds remarkable capability for sustainable energy applications. The hydrogen-ammonia blends attain a stability between performance and emission decrement, exhibiting their assurance for cleaner gas turbine technology. Eventually, the present research promotes the development of alternative fuel approach in gas turbines, aiming the transition to cleaner energy solutions.
