The thesis examines how the shipping transport sector is working to reduce its greenhouse gas emissions. It is especially focusing on, that the Danish government is making plans to erect an energy island that is meant to produce green fuel for the shipping industry. The report aims to evaluate if the 10 GW installed wind turbine capacity can supply one ship sailing on a specified route made for this thesis, but with a focus on a normal Europe-Asia container ship route. The route which is looked at is from Esbjerg in Denmark to Singapore.The method used in the thesis is different in the different parts. The green fuels that are being examined are e-methanol and green ammonia. The pathway for their production is investigatedthrough literature research in terms of production efficiencies. The same applies to the possible pathways of utilizing the energy from green fuel. For gaining knowledge about the energy production from the wind turbines a simulation program called “energy plan” has been used. The energy usage for one ship has been estimated by taking the route mentioned above and data from the “triple E series”1of ships from Maersk along with data from the engine manufacturer MAN-ES. All this data has been compared to evaluate how the green energy production matches the usage.The study shows that the energy island can easily deliver enough energy to one ship. The yearlyproduction is sufficient to deliver enough green energy to supply 20 ships traveling on the routethroughout the year using ammonia as fuel and solid oxide fuel cell technology. Although it can supply enough green fuel it is questionable if green fuel is the best utilization of offshore energy, from an installed capacity that is almost 4 times greater, than the current installed offshore capacity in Denmark.
