Sustainable and autonomous design - utilization of waste energy with green hydrogen use, Ikaria Island

Summary

In the era of the climate crisis, the search for sustainable energy solutions is not only desirable but necessary for the survival of future generations. Greenhouse gas emissions and the depletion of natural resources demand an immediate shift towards green energy, which is the key to ensuring a sustainable society and reducing the use of fossil fuels.The European Union, recognizing the importance of energy autonomy, places the transition of its islands at the forefront and the implementation of innovative systems that will minimize their dependence on fossil fuels by 2030. Greek islands, particularly the example of Ikaria, demonstrate that small communities can become pioneers in addressing the energy crisis by utilizing sustainable energy sources to replace fossil fuels and reduce carbon dioxide emissions.Thus, this thesis aims to investigate how communities, such as Ikaria, can act as autonomous energy systems by replacing the exploitation and depletion of common fossil fuels with new sustainable and environmentally neutral techniques. Specifically, through modeling and scenario creation using Python software, the design of a sustainable and autonomous system will be examined. This system will incorporate renewable energy sources (RES) and the production and storage of “green” hydrogen. This system will expand the existing storage capacity of the island's pumped-storage system, thereby minimizing wasted energy and the burning of fossil fuels for electricity generation. Finally, two additional parameters will be considered: energy savings and the elevation at the Peziou dam to enhance the system further.
