Thermodynamic Modeling of Binary Cycles Looking for Best Case Scenarios

Power plant design is done with the help of numerical models. For binary power plants using other working fluids than water numerical models were set up and applied on settings describing typical geothermal resources in Germany. Charts come along with the numerical results and aid in understanding the principles of the cycles. Parameter variations show that installation of a geothermal power plant in the North German Basin requires brine temperature above 100°C and that mass flow rates over 50 m/h are favourable to get to a commercial application
