Thermodynamic analysis and performance optimization of transcritical power cycles using CO2-based binary zeotropic mixtures as working fluids for geothermal power plants

•TPCs with CO2-based binary zeotropic mixtures are investigated for low-temperature geothermal power plants.•Parametric optimization is performed by the pattern search algorithm (PSA).•Exergy, exergy and economic analyses are conducted. Transcritical power cycles (TPCs) using CO2-based binary zeotro...
