Application of renewable energy technologies for eco-friendly sea ports

The present study aims at quantifying prospective reductions of ships' emission of GHG in addition to the expected economic impact in case of applying various renewable energy technologies for seaports. As a case study, this paper investigates the prospect of converting Damietta Port, Egypt, to be an eco-friendly port with the focus on technical, logistic and financial requirements. The results prove the techno-economic feasibility of both offshore wind and fuel cell energy resources for the selected port. The paper's outcomes prove that the fuel cell, followed by a combined system of wind turbines and fuel cells appear to be the optimum selection with reference to green port technologies with an electricity unit cost of 0.10 and 0.11$/kWh, respectively. Furthermore, using of fuel cells and offshore wind turbines as green power strategies would achieve a reduction of CO2, NOx and CO emissions by 32,176, 8.32 and 53.2 ton per year, respectively.
