FUTURE FERRIES WILL BE FULLY ELECTRIC The green transition of the Danish ferry service is powering on. The technological development opens new doors, and the Danish shipping companies are ready to exploit these new opportunities. Within the first half of 2017, the first Danish ferries will transit to electric mode - and many others will follow in the coming years. - It is obvious that when 240 motorists turn off their engines and enjoy a cup of coffee, while electricity from wind turbines transports them by ferry across the Øresund, it is true green transition, says Jakob Ullegård, director of the Danish Shipowners’ Association, referring to what will be the world’s largest electric ferries, the two HH-ferries Tycho Brahe and Aurora that are converted to electric mode by the end of the first half of 2017. LARGE BATTERY PACKS The ferries will have 640 batteries at 6.5 kWh installed on their top. A fully automatic laserguided robotic arm connects the batteries to the grid every time the ferries are in port. Typically, they are only in port around 5-9 minutes at a time, so a very high voltage will be used. Shipping is part of the green transition, and Danish shipping is in front. danish maritime magazine

The shipping companies have a clear policy that the maritime share of CO2 emissions worldwide must be constant. Therefore, it is natural that the Danish ferry service evolves in that direction – and swiftly. ENERGY EFFICIENCY One of the obvious ways to make the ferry service greener is through energy efficiency - like Scandlines’ new hybrid ferries between Gedser and Rostock. 2/3 of the fuel consumption is cut per car with the new ferries. But other ferry services are also in transition. This applies to Molslinjen, that has worked to save fuel: - We have worked purposefully to optimize our operations. In a span of a year, we have achieved saving over five percent in fuel consumption through a variety of initiatives. We primarily do this to strengthen our bottom line, but it

is also a step in a greener direction, says Carsten Jensen, Managing Director of Molslinjen. LNG Fjord Line use LNG from a new tank plant at the Port of Hirtshals on routes between Norway and Denmark. This means lower emissions of sulfur, NOx and particulates. MORE ELECTRIC FERRIES ON THE WAY In addition to HH Ferries’ conversion of Tycho Brahe and Aurora to electric ferries, a new electric ferry is being built on Søby Shipyard. When it is finished, it will be deployed on the lines between Søby, Faaborg and Fynshav. In addition, there’s the smaller North Jutland route from Kleppen to Venø that is currently converting to hybrid operation, but is expected to convert to electric operation in the long run.
