The article discusses a detailed techno-economic analysis conducted in Iran to evaluate the feasibility of utilizing ammonia and hydrogen mixtures for clean power generation. Ammonia is highlighted as a versatile energy carrier with zero carbon emissions potential, suitable for power production. The study includes a technical analysis focusing on different ratios of ammonia and hydrogen in the fuel mixture, demonstrating variable power output levels in gas turbines. By maintaining the turbine inlet temperature consistent with the SGT5-2000E turbine, the power output ranged from 192.8 to 229.0 MW, with certain ratios showing maximum efficiency. Furthermore, an economic analysis was carried out to assess the impact of fuel costs and interest rates on the levelized cost of electricity production. The study also involved sensitivity analysis on various combined ratios of ammonia and hydrogen, determining the ideal economic ratio for power generation. The price of ammonia fuel was calculated between 222 $/ton to 2000 $/ton, leading to a range of levelized costs of electricity production from 91.7 $/MWh to 673.4 $/MWh. Moreover, the article presents an economic comparison between the utilization of ammonia-hydrogen mixtures and natural gas fuels, showcasing the potential of ammonia-hydrogen as a promising alternative for power generation without carbon emissions. With its ability to serve as a clean energy carrier and provide suitable storage for renewables, the ammonia-hydrogen fuel mixture emerges as a viable option for sustainable power production.
