    Investigation of the Best Possible Methods for Wind Turbine Blade Waste Management by Using Gis and Fahp: Turkey Case
    (Springer, 2022) Öztürk, Samet; Karipoğlu, Fatih
    The aim of this study is to present the status and projections of wind turbine blade retirement in Turkey; to investigate the number of retiring WT blades in the regional, manufacturer, and material aspects; and to discuss the management methods for retired WT blades. To determine the best possible wind turbine blade waste management methods for Turkey, a combined application of Geographical Information Systems (GIS) and the Fuzzy Analytical Hierarchy Process (FAHP) is used in this study. It is found that around nine thousand WT blades will become waste between 2020 and 2039 in Turkey, corresponding to around 80,500 tons of waste. On average, 52,325 tons of glass/carbon and 28,175 tons of polymers will be accumulated between 2020 and 2039 from wind turbine blades. More than half of the WT blade waste will come from two WT manufacturers, namely, Enercon and Nordex. Aegean and Marmara regions will provide 74% of the blade waste, where 33% of them will be 2 MW and 2.5 MW sizes of WT blades. Furthermore, a case study is applied to Izmir city to demonstrate the results of FAHP for finding the best available method to dispose of WT blades. The results show that using blade waste as filling material is the best alternative, while waste-to-energy is the last favorable option for blade waste management. Finally, sensitivity analyses are applied to demonstrate the robustness of the results for the inclusion of new alternatives and the bias of experts’ judgments.

    Gis-Based Optimal Site Selection for the Solar-Powered Hydrogen Fuel Charge Stations
    (Elsevier, 2022) Karipoğlu, Fatih; Genç, Mustafa Serdar; Akarsu, Beyhan
    Energy consumption which is the most critical input in daily life is increasing constantly because of the growth of the world population and development of the devices. The transportation industry which is responsible for almost half of all worldwide emissions is switching to innovative devices run on renewable energy. Renewable-powered charging stations are important for reducing the environmental impact of vehicles. The objective of the study was to determine the best hydrogen charge station locations and rates which are supplied by coupled solar power plants. The GIS-based assessment was carried out with proper data from data sources such as Copernicus Land Monitoring (CLC 2018), and Global Solar Atlas (GSA). For the determination of suitable regions for solar power plants, eight sub-criteria were assessed under technical (C1), accessibility (C2), and environmental (C3) main criteria. Afterward, the obtained result map layer and suitability of the six determined water bodies, located in the study region, were investigated by assuming the buffer zone value. Results showed that the study area had suitable regions of 38.1 km2 indicating that %22.4 of it was convenient for the solar power plant investments. While Cihanbeyli Lake does not have the highest suitable region, the biggest suitable area inside the buffer zone of lakes was determined as the Ağcaşayar Dam. The maximum annual solar production level is obtained as 1,919 MWh/year in the Ağcaşayar Dam, with a hydrogen production of 34,933 tons/year. Consequently, the Ağcaşayar Dam is the best suitable destination for a hydrogen fuel station in Kayseri.
