Optimization of geothermal- and solar-driven clean electricity and hydrogen production multi-generation systems to address the energy nexus

Given the limited sources of fossil fuels, mankind should find new ways to meet its energy demands. In this regard, geothermal and solar are acknowledged as reliable, safe, promising, clean means for purpose. research study, a comparative analysis is applied on geothermal- solar-driven multi-generation systems electricity hydrogen production through exergy assessments. The consist an organic Rankine cycle, proton electrolyte membrane electrolyzer, thermoelectric generator subsystem. Engineering Equation Solver software has been utilized in order model system obtain output contours, sensitivity analysis, destruction. results were obtained considering ambient temperature Bandar Abbas city case study. was performant over system, with 11.21% higher 0.17 % efficiency. According turbine efficiency, evaporator inlet temperature, suitability criterion, pump mass flow rate most influential parameters. Also, showed that utmost system's destruction pertinent least related pump. addition, produces 352,816 kWh 174.913 kg electrical power during one year.
