Hydrogen as a fuel has drawn the attention of policymakers and scientists in recent years. Also, the exploitation of solar energy based-technologies cannot be ignored due to solar energy abundance and free nature and due to the problems caused by fossil fuel consumption. On the other hand, the integration of solar energy systems with other common technologies can improve the overall performance and reliability of the power plant. The main aim of this paper is to conceptually design a 0.5 MWel power plant based on solar farms consisting of photovoltaic (PV) panels and parabolic trough collectors (PTC) to generate power and green hydrogen. The proposed power plant uses an organic Rankine cycle (ORC) system to generate electricity. An alkaline electrolyzer is installed to produce green hydrogen and oxygen gas. The thermal energy required in this cycle is obtained by a solar farm based on concentrating collectors. On the other hand, since solar energy is intermittently in nature, an electrical energy storage system (PH-CA) has been installed in the power plant. The performance of the power plant has been compared with the assumption of implementation in two different climatic conditions in Asia (Kashi and Langfang). Furthermore, three different scenarios based on different capacities of solar PV and ORC sections have been suggested. The proposed energy system and its configuration have a new design that has not been reported in the literature. It was found that the proposed power plant in Kashi can be better than Langfang. Because the power plant in Kashi needs fewer solar arrays and collectors compared to Langfang. In addition, the exergy destruction of the power plant in Kashi is less than Langfang. Also, the lowest exergy destruction of power plants and required organic fluid in both cities is related to the third scenario. Results indicate the size of the storage system should be approximately 2245 m3. Furthermore, the storage efficiency of the power plant was 62.16 %. Finally, nearly 1.4 kg/h of green hydrogen and 2.7 kg/h of oxygen gas can be obtained from the proposed plant at the selected location.
