Abstract

In this study, a new geothermal energy-based multigeneration system for producing electricity, fresh water, drying air, hot water, hydrogen, and ammonia is proposed and studied in detail through system analysis and performance assessment. A detailed thermodynamic assessment is performed in order to investigate the whole plant performance and conduct parametric analyses to investigate how the plant effectiveness is affected by varying working conditions along with the state properties. The overall plant is analyzed and evaluated by utilizing the Engineering Equation Solver (EES) software program. According to the analysis outputs, the thermodynamic efficiencies of the multigeneration system are computed as 75.07% energetically and 72.26% exergetically. Furthermore, parametric analysis results indicate that geothermal inlet conditions are the most influential parameters on the energetic and exergetic performances of sub-plants and the whole plant.
