Experimental use of renewable and sustainable hydroxy gas (HHO) and hydrogen (H2) enhanced ammonia fuel mixture in gas turbines

Energy is the most crucial need of our present and future, and hydrogen is the key to clean energy solution and even to the clean future. Today, the important challenges of utilization hydrogen in power-producing applications (internal combustion engines and fuel cells) are known as transportation and storage and these create a big hesitation regarding application safety. Ammonia, which is the most promising alternative to solve those problems of hydrogen applications, provides the possibility of storage in liquid form at low pressures and high temperatures. Although the ammonia production processes were not mentioned in detail in the study, the clean production of the hydroxy gas obtained by using solar energy was explained. This study was carried out to investigate how to compensate the drawbacks of using ammonia as the main fuel in a gas turbine by hydrogen and hydroxy-gas enrichment. During the experiments, propane that is standard working fuel of the gas turbine, neat ammonia, as well as a constant 10 L/min ammonia fuel enriched with 3 L/min, 5 L/min, and 7 L/min hydroxy gas and 3 L/min, 5 L/min, and 7 L/min H2 were utilized. The performance outputs obtained in the studies with propane in the gas turbine used in the experiments were compared with the ammonia outputs enriched with H2 and HHO. During these comparisons, fuel enrichments by volume were categorized and then separate comparisons were made for each fuel enrichment type. The results show that hydroxy gas enrichments lead to improvements in performance data and emission values due to the absence of any carbon emissions. Besides the improvements in performance and carbon emissions, the important issue is that NOx emissions should be kept under control. Although no filter is used, it has been reported in the literature that these NOx and unburned NH3 emissions can be prevented by using Selective Catalyst Reduction (SCR).
