Özet

In this study, solar-powered green hydrogen production has been presented. Evacuated tube heat pipe (ETHP) collector is used to benefit from solar energy in the project. Thermal energy is obtained through the solar radiation collector. With this thermal energy, electrical energy is produced by using an organic Rankine cycle (ORC). Then, the help of the electrical energy by electrolyzer, hydrogen energy in the gas form is obtained. Thermodynamic analysis of all the work to be done is carried out with the Engineering Equation Solver (EES) program. Exergy analysis of ETHP solar collector found as %30.86. The amount of hydrogen obtained from PEMe is find 310 cc per min. Moreover, approximately 135-170 W of electricity generated from the turbine for hydrogen production is sufficient.
