Abstract

In this research, a novel geothermal power-based combined plant is planned for various valuable products generation. A flash-binary geothermal plant, an organic Rankine cycle plant, a transcritical-CO2 plant, a hydrogen production plant, and a magnetic refrigeration plant are integrated together to generate beneficial products. In the evaluation part of the paper, thermodynamic analyses, validation studies, and parametric studies are performed. According to the assessment outputs, the total power production is found as 20,220 kW, the heating capacity is 8,726 kW, and the cooling generation rate is 1,341 kW. In addition, the hydrogen production rate of the designed energy plant is 0.0124 kg/s.
