Abstract
This study investigated a hybrid system that integrated geothermal energy for both electricity generation and water desalination. The system optimized resource utilization and enhanced overall efficiency by combining geothermal heat with advanced desalination technologies and power generation processes. The proposed system focused on Organic Rankine Cycle (ORC) technology for applications in water desalination combined heat and power (CHP) generation and the recovery of low-temperature geothermal heat. Several ORC configurations were explored to obtain power from low-temperature heat sources. A mathematical model of the system was developed using Aspen HYSYS simulation software incorporating thermodynamic principles to analyze heat and mass transfer within the system. Multi-Effect Distillation (MED) and ORC processes were involved. The economic feasibility of the hybrid system was assessed. The results indicated that the electricity production cost was $0.07 per kilowatt-hour and the desalination cost was $1.05 per cubic meter of water. The system’s output was estimated at 1,800 kW of electricity and 4,750 cubic meters of fresh water per day.
