International 100% Renewable Energy Conference



Energy System Analysis and Modelling of an Electric-Powered Ferry


In parallel with the increasing sensitivity of the international community in recent years on that harmful greenhouse gas emissions causing global warming and climate change should be reduced and the United Nations (UN) Framework Convention on Climate Change and Paris Agreement on Climate Change, International Maritime Organization (IMO) that is the UN specialized agency with responsibility for the safety and security of shipping and the prevention of marine and atmospheric pollution by ships has also increased its efforts in order to reduce emissions from international shipping in recent years. IMO that in particular aims to reduce carbon dioxide (CO2) emissions from maritime transportation by 50% until 2030 and by 70% until 2050, compared with 2008, has established very important regulations during the last 15 years. Briefly, these regulations are related with Energy Efficiency Design Index (EEDI) for reducing CO2 emissions of new ships, Ship Energy Efficiency Management Plan (SEEMP) and Data Collection System (DCS) for Ship Fuel Consumption for existing ships, Sulfur (S) content limits for marine fuel oil, Azoth oxide (NOx) emission limits for internal combustion marine engines and Emission Control Areas (ECA) in terms of NOx and Sulfur oxide (SOx) for the different sea areas of the world. All of those regulations and therefore additional costs have accelerated the maritime industry’s efforts to make more use of the alternative/renewable energy sources onboard ships and at ports. Especially in Northern European countries, which are prominent with their fjords within the ECAs, the use of all-electric or hybrid ferries with energy storage technology in Li-ion batteries has started to become widespread instead of using fossil-based fuels in the maritime transportation. In accordance with 11th Development Plan of Turkey, it is envisaged that the use of the electric-powered ferries for passenger and car transportation in short-distance will also become widespread in the near future of Turkey. In this study, the objective is to analyze and model the energy system of an electric-powered ferry using for maritime transportation. With this aim, a Reference Energy System (RES) for an electric-powered ferry, which consists of resources, conversion process & technologies, final energy carriers, demand technologies & sectors, are established and analyzed.



Fatih YILMAZ – He was born in Sivas in 1979 and completed his primary and secondary schools in the same city. In 2002, he graduated from Naval Architecture Department, Faculty of Marine Science of the Karadeniz Technical University. Due to the professional qualification exams, he began to work as a Flag and Port State Control Officer at the Under Secretariat for Maritime Affairs, Prime Ministry. During the business life, he inspected many ships in accordance with the rules of the International Maritime Organization (IMO) and the International Labour Organization (ILO) as well as with national rules. He also attended many international trainings & meetings in the field of maritime affairs. He still working at the Department of Ship Inspection at the Ministry of Transport and Infrastructure. In parallel with his business life, his Master Thesis study on “Energy System Analysis and Modelling of an Electric/Hybrid-Powered Ferry Using for Maritime Transportation and its Environmental & Technical Investigation” at the Department of Marine Engineering, National Defense University (NDU) Turkish Naval Academy has been ongoing. His main expertise and fields of study are related to shipbuilding and marine technologies, maritime safety & marine environmental protection, energy efficiency & management in maritime transportation and maritime trade logistics.
