Cost analysis of wind-electrolyzer-fuel cell system for energy demand in Pinarbasi-Kayseri

In this study, the hydrogen production potential and costs by using wind/electrolysis system in Pinarbasi-Kayseri were considered. In order to evaluate costs and quantities of produced hydrogen, for three different hub heights (50 m, 80 m and 100 m) and two different electrolyzer cases, such as one electrolyzer with rated power of 120 kw (Case-I) and three electrolyzers with rated power of 40 kW (Case-II) were investigated. Levelised cost of electricity method was used in order to determine the cost analysis of wind energy and hydrogen production. The results of calculations brought out that the electricity costs of the wind turbines and hydrogen production costs of the electrolyzers are decreased with the increase of turbine hub height. The maximum hydrogen production quantity was obtained 14192 kgH(2)/year and minimum hydrogen cost was obtained 8.5 $/kgH(2) at 100 m hub height in the Case-II.
