Özet

Geothermal energy is one of the most reliable sources of environmentally friendly energy. In this research, an advanced combined geothermal power plant is not just planned, but thoroughly examined using a comprehensive set of evaluation approaches including thermodynamic, environmental, and exergo-environmental. This system comprises a geothermal cycle, two ORCs with Ammonia fluid, a PEM electrolyzer, an Ammonia synthesis module, and a reverse osmosis desalination. This newly developed configuration can produce clean electricity, green hydrogen, ammonia, freshwater, and heating. To determine the cycle performance and relationship between exergy destruction and the environment, various analyses, which are energetic and exergetic performance, exergy destruction rate, carbon-dioxide emission reduction rate, and environmental index evaluation, are conducted parametrically. The examination results illustrate that the net electricity capability of the modeled plant is 2046 kW. Afterwards, 0.002367 kgs−1 green Hydrogen and 0.009436 kgs−1 ammonia can be produced with this designed system. A total of 4945 kW exergy destruction is observed in this designed system. Additionally, the newly configured cycle has an energetic performance of 26.31% and an exergetic performance of 33.09%. Overall, the comprehensive evaluation of the system instills confidence in its reliability and potential for further carbon dioxide emission reductions.
