Simulation of hydrogen production system with hybrid solar collector

• Hydrogen and oxygen production is simulated.
• Electrolysis of water by hybrid solar collector conducted.
• Simulation created accordance meteorological data of three different locations.
• Results show importance of temperature according to the pressure in production of hydrogen and oxygen.

In this study, the simulation of hydrogen production system demonstrated with electrolysis of water by hybrid solar collector. The mathematical model created by in accordance with the system flowchart. For this numerical study, three cities located in west, middle and east of Turkey, were considered which are Istanbul, Konya and Erzurum.Borland Delphi 7 programming language used for numerical analyses. The insolation and solar irradiance of these cities were taken into consideration and the values of the solar irradiance of the cities compared to each other. For each case, a simulation of the system made keeping temperature constant (373 K) and increasing the pressure up to 0.1 MPa and 0.5 MPa. In the other case, the pressure kept at constant (0.1 MPa), the temperature increased up to 573 K. It observed that City of Konya was quite convenient in terms of hydrogen and oxygen production compared to Istanbul and Erzurum, and the pressure had a very low effect on hydrogen and oxygen production; but the temperature is an important component in hydrogen and oxygen production system. The results for hydrogen production compared to literature and found a difference around 1.08%.
