Economic evaluation of solar-hydrogen hybrid system with installed power of 1 Mw and 5 Mw in İskenderun Organized Industrial Region

In the study, the production potential of hydrogen production for Iskenderun organized industrial zone was evaluated. Considering the geographical characteristics of the region, the potential of 30000 hours of electricity and hydrogen production per year for solar power plants that have been established or are likely to be established is examined. In the study, 4 different scenarios were selected and economic analysis was carried out. In Scenarios 1 and 2, the cost of H2 (Hydrogen) was calculated by integrating a 120 kW AEM(Anion electrolyte membrane) electrolyzer in addition to the 1 MW solar power plant and storing the produced hydrogen in Type 1 (low pressure, metal material tank) and Type 4 (high pressure composite material tank) tanks. In Scenarios 3 and 4, a 1MW AEM electrolyzer is used with the solar power plant increased to 5 MW. In these scenarios, the hydrogen produced is stored in Type 1 and Type 4 tanks and the H2 cost for transportation to the end user is calculated. In addition, in 4 scenarios, different evaluations were made considering the situation with and without the solar power plant included in the system. The production cost of H2 gas reaching the end user is more economical in the system including the solar power plant. For example, when Scenario 2 is considered, while the production cost of H2 gas is $16.22/kg in the system without solar power plant, this value is calculated as $10.69/kg in the hybrid system where solar power plant is included. In the 4 scenarios where solar-hydrogen hybrid system was created, the production cost of H2 gas was determined as 58.87 $/kg, 10.69 $/kg, 6.65 $/kg and 4.87 $/kg, respectively.
