E-Ferry Ellen, the first 100% electric ferry, can travel more than 20 nautical miles. Usually, you can find it crossing between the island ports of Fynshav and Søby. It can carry 30 vehicles and 200 passengers.
Ellen is equipped with two electric motors and a 4.3 MWh battery pack. They charge the battery pack with surplus wind power from the Danish island, which means that it is always powered by clean energy. The battery system of the Swiss Leclanché SA has an unprecedented capacity to store 4.3 MWh. It is estimated that it will prevent the emission of 2,000 tons of CO2 per year.
In the world of fossil fuel shipping, the price of high sulfur heavy oil has been plummeting since the International Maritime Organization (IMO) lowered new rules. The use of cleaner fuels or the installation of chimney cleaning systems is required, which is very expensive and takes up a lot of space. As a result, the demand for heavy and dirty oil has been falling rapidly.
