| dc.description.abstract | This thesis study proposes solar and geothermal based three multigeneration systems. System 1 consists of a bifacial photovoltaic (BiPV) plant, multi-effect distillation (MED) desalination unit and, proton exchange membrane (PEM) electrolyzer. Systems 2 and 3 additionally consist of the copper chlorine (Cu-Cl) thermochemical hydrogen production cycle integrated with a concentrated solar power (CSP) and supercritical geothermal systems, respectively. Electricity, freshwater, hydrogen, and space heating are produced as useful outputs for the communities in Gokcebayir in Turkey, Geyser in the United States, and Shinozaki in Japan. All of the proposed systems are designed, modeled, and analyzed with hourly sensitive annual simulations. According to the results, the highest overall energy efficiency is calculated for system 2 as 27.4%, and the highest overall exergy efficiency is calculated for system 3 as 18.6%. Integration of the Cu-Cl cycle with solar and geothermal based systems is led to prevent waste production and achieve sustainability goals. | en |
