Techno-economic analysis of solar/wind power based hydrogen production

In the presented paper, it is aimed to determine the cost analysis of solar/wind hybrid power-based hydrogen production for different system configurations. In line with this aim, a hybrid energy system consists of various wind turbines having different rated powers (500 kW, 900 kW, 1300 kW and 2000 kW) and operated at different hub heights (80 m, 100 m and 120 m) integrated with two different solar panels (Panasonic-330W and Kyocera 315W). In addition, the electrolyzers having different rated power (18 electrolyzers each with a power of 48 kW, 4 electrolyzers each with a power of 215 kW, 2 electrolyzers each with a power of 430 kW and 1 electrolyzer with a power of 860 kW) are added to the solar/PV hybrid system. To evaluate the performance of the hybrid system, a case study was carried out to implement the proposed system in Iraq. The site selection in Iraq was obtained with a geographical information system (GIS). For all calculations were performed for the cities of Basrah, Wasit and Anbar. The maximum hydrogen production quantity having a value of 49,150 m3H2/year is obtained in Basrah and hydrogen production cost in this case is equal 0.752 $/m3H2. This cost can be decreased to 0.723 $/m3H2 if the excess energy is sold to the grid. In all considered cities, Basrah has the remarkable electricity and hydrogen production potential between the considered cities in Iraq.

Automated summary

The paper focuses on analyzing the cost of solar/wind hybrid power-based hydrogen production for different system configurations. Different wind turbines with varying rated powers and hub heights, as well as different types of solar panels, were integrated into the hybrid energy system. A case study in Iraq was conducted, and Basrah was found to have the highest potential for electricity and hydrogen production among the considered cities.
