4th International Hydrogen Technologies Congress, Edirne, Turkey, 20 - 23 June 2019
In this study, ocean current turbines and off-shore wind turbines are employed to produce electricity, hydrogen and fresh water. Fresh water and hydrogen are obtained by reverse osmosis unit and electrolysis process by employing produced electricity through current and wind turbines located in Bosphorus, Istanbul. Hydrogen storage and transportation options are discussed in terms of their costs. Parametric studies are conducted to evaluate the system with different variables including the turbine velocity, turbine blade radius, ocean, and wind velocities. The main purpose of this system is to provide a sustainable and renewable energy based system. This provides diversity in electricity production and safeguards the security of electricity supply. The overall energy and exergy efficiencies are calculated as 52.14 and 44.77%, respectively.
