Abstract

The objective of the proposed study is to examine the performance of an integrated hydrogen generation system based on solar energy. For this purpose, CO2, a natural fluid that does not harm the environment, was used as the working fluid. The system is comprised of the Photovoltaic/thermal (PV/T) panels, a pump, a condenser, a turbine, a Proton Exchange Membrane Electrolysis Cell (PEM-EC), and hydrogen and oxygen storage tanks. MATLAB and EES software programs are utilized to perform the performance assessment of the system. According to the analysis made on data for 17th August of İzmir, the net power generation from the PVT panels was calculated as 2696 W, the net power generation from the transcritical C02 Rankine cycle was 73.03 W, and the hydrogen production was 0.514 g/h.
