Signing Ceremony 1

EU Horizon 2020 partnership for demonstration E-ferry have signed the Grant Agreement at an official event at the City Hall on Aeroe yesterday.

The demonstration project is scheduled to cover four years starting June this year.

First year will be for detailed design and approvals. Second year covers the newbuilding period and some test and sea trials. The two last years will be a demonstration period where the E-ferry concept will prove its feasibility in full scale operation with passengers.

The partnership is coordinated by the Municipality of Aeroe and the Comitee for Sustainable Energy. More information about the demonstration project can be found on the website of the municipality at


At the 28th of January 2015 partners have recieved confirmation from the EU Horizon 2020 administration that the application for a demonstration E-ferry project has been approved of and it will now proceed to the state of Grant Agreement preparation with the 10 partners directly involved in the demonstration project. The partners now have 3 months to negotiate the final contracts with the EU Horizon 2020 administration.

The 17 million € application will allow the partnership of the Municipality of Aeroe, Søby Shipyard, Siemens, Tuco Marine, Jens Kristensen Consulting Naval Architects, DNV GL, Interferry, Danish Maritime Authorithy, Hellenic Institute of Transport, The Danish Institute of Fire and Security Technology to proceed with the design and new building of a prototype electric ferry having the majority of investments paid by the Horizon 2020 funding.

Other partners will be affiliated as associates in the prototype demonstration project.

The first E-ferry is planned for the route from Søby to Fynshav and Søby to Fåborg in 2017 allowing one year for finalising the detailed design and one year for new building. The design will allow for operation all year around in harsher weather conditions than the present ferry on the route and travel time is reduced up to 25 percent.

The Green Ferry Vision market study has been uploaded under deliveries. Europe

The study of three Scandinavian countries shows a potential for conversion of almost 200 domestic ferries within the next decade provided that infrastructural changes of the electrical grid is paid by public investments. If the results were to be extrapolated to all European coastal countries this indicates a future market of more than thousand electrically operated ferries giving room for a new niche industry in Europe and many innovative producers.

The Principal from Marstal Navigationsskole Mr. Jens Naldal and Mr. Thomas Estrup from the Municipality of Aeroe attended the Ship Efficiency Award Conference in London at the 2nd of October 2014. The Green Ferry Vision project was nominated in the category "The One to Watch" but did not win the price. In the category "Initiative of the year" a partners of the Green Ferry Vision project, Siemens, was involved in the winning Scandlines/Corvus hybrid project on the Baltic ferry route Roedby-Puttgarten. We could hope to be nominated again when the Green Ferry Vision project has materialized into a full scale demonstration project.

The Green Ferry Vision project for fully electrical and energy efficient ferries is announced to be one of finalists in the 2014 Ship Efficiency Awards hosted by Lloyd's Register and organised by Fathom Shipping Events in London.

Application for EU Horizon 2020 call topic, "Towards the energy efficient and emission free vessl", has been submitted by the partners of the demonstration project.

The process of evaluation is estimated to be of around five months, thus in January we hopefully can proceed with the work for a grant agreement if evaluation is positive.

Demonstration project will be in three parts: One year for project design and basic approvals, one year for building/production and tests and one year of demonstration in commercial operation.

The asked grant constitues for amount of almost 17 million €. In addition private partners will contribute with funding. This, however, is not the expected price for an E-ferry when it enters market in the future. Also cost of Research & Development for shore charging connections capable of operation at all tides and in all weather conditions with up to 4 MW power and numerous other solutions will be involved e.g. lightweight machinery and equipment as well as lightweight ship building materials. The landinfrastructure in ports of demonstration will also have to be modified including new electrical grid infrastructure. Finally an EU grant would help ensure the dissemination and exploitation of results from the full scale E-ferry demonstration project aiming at sailing on two routes from the island of Aeroe to the island of Fyn and Als respectively.

At the Island of Aeroe two fully electrical boats has been sailing within the last month. A member of the intial green ferry vision group, Mr. Flemming Boye did launch a carbon composit 1 to 10 scale model of a catamaran ferry. The propulsion is fully electrical and it has made it for sea trials in open sea.

 At the event "Aeroe Day" tourists and locals were inveted to harbour sight seeing in the port of Soeby where a fully electrical yacht was sailing for the day. The event was well visited and funded by the Comittee for Sustainable Energy on Aeroe. The local newspaper Fyns Amts Avis wrote a article about our planned demonstration project. It can be found in the Sunday edtition from 15th of June.

EU Commission

The administration has scored our stage 1 application for a Horizon 2020 full scale demonstration project. We have obained enough points to proceed with the more detailed stage 2 application. The Municipality of Aeroe will be the lead partner in th demonstration project. Deadline for the stage 2 application is the 28th of August. The Horizon 2020 demonstrationproject is planned to be a 3-year newbuilding and test period starting in 2015.

The law proposal on exemption of energy tax on electricity charged ashore for use on board ships above 400 GT has been approved by the Danish Parlament at 27th of may 2014. The law will be effectuated from the 1st of July but parts of it will first come into effect when the EU Comission has approved of the exemptions according to the EU energy directiv.

In our comments to the law ptoposdl we did critizise the relatively high 400 GT requirement, as some smaller island ferries and harbour buses will not be covered by the exemption. The planned green ferry in this project is well beyond the 400 GT limit.

Also a change in the law for energy supply entities needs to be adjusted with exemptions for the PSO (Public Service Obligation) tarifs if total equivalence to fossil fuel taxations should be obtained.



Extensive trials carried out by Imtech Marine on the Scottish hybrid fuel/battery ferry MV Hallaig has showed that the actual fuel savings with the innovative hybrid system, consisting of diesel electric in combination with battery technology, reached 38%, Imtech Marine said in a press release.

CMAL operates the ferry on the west coast of Scotland and savings are divided in two categories."On closer examination of these fuel savings, some 28% came from shore charging the batteries overnight, making the system more efficient, and the remaining 10% is the result of the fact that Imtech Marine is using the battery energy in a "smart" way via our new Energy Management System (EMS)." Eventually, the batteries will be charged using the island's own wind energy, making the system even more environmentally friendly.

Jim Anderson of CMAL says: "In our initial estimates we had planned to save at least 20% on fuel, when we received the reports that the actual fuel savings were almost twice that number we were pleasantly surprised. With this achievement the CO2 emissions have been effectively reduced so we also made a major step towards the reduction of the carbon footprint."

Read the press release from Imtech here.


One of the most significant barriers to the introduction of fully electrically propelled ferries will be the difference between taxation of fuel and electricity for ships. As for now fossil fuels for national and international ferries are subjected to no tax when used for propulsion. This is not the case for electricity charged ashore to batteries on board. Electricity charged for propulsion is subjected to full Danish taxation. With the present regulation it will be cheaper to produce the electricity on board using diesel generator sets thus poluting with CO2, NOx, Sulphur and particle emissions. The new law proposal will seek to gain equivalence between fossil fuel types and electricity by exempting all taxes on electricity charged when ships are at berth.

Partners from the green ferry vision have made an answer to the law proposal asking for the tax excemption to apply for smaller merchant and passenger vessels than 400 GT. The answer to the proposal is also in Danish can be found here: pdffile 64 px

microphoneThe number of green and blue conferences in the spring is high. The green ferry vision has been invited to speak to a number of these. However we also need time to finish our study why attending all conferences has had only a secondary priority. For now we will be represented at:

The Blue Business Conference at CBS at the 27th of February, arranged by CBS, EMUC, The Danish Maritime Fund.

The Conference on green business opportunities in Aaloborg at the 5th of March arranged by MARCOD, EMUC and Skibsteknisk Selskab.

First seminar for the smart energy island and minicipality programme and funding in Fredericia at the 1st of April arranged by KL and Energistyrelsen.

The Interreg Conference on Baltic Ferry routes in Glücksburg at the 14th of May, Lead partner Aeroe Turist- og Erhvervsforening.

We are sorry that we do not have the time right now to commit to all relevant invitations but expect to return and participate more when the result of the feasibility study have been published.


energiislandThe green ferry vision is a co-partner in the Smart Energy Island project of the Island of Aeroe. In this project the municipality of Aeroe will be the lead partner and further design of the first demonstration ferry will be a part of the Smart Energy Island project. This way the next phase of the green ferry vision can be financed namely design of a demonstration ferry.

On the 20th of December it was announced that the applied funding from the Danish Ministry of Climate and Energy had been granted. Read more about the Smart Energy Island.

lithium ion batteryAt the 10th of december TINV (Transportens Innovationsnetværk) had arranged a seminar on the future of batteries in transport. Several partners from the green vision ferry project attended the one-day seminar. The seminar was held at the Danish Technological Institute in Aarhus where the latest studies were presented and finally a visit to the laboratories had been arranged.

The event was a great opportunity for the partners to network and at the same time get a deeper knowledge into the problems and solutions of storing energy in mobile units. The Lithium Ion battery technology is for the time being the most developed for our purpose. However other technologies are in the pipeline but needs further development for maturity to market and ship use.

At the seminar also representatives from Småøernes Færgeselskab (Danish small island ferries) participated. They will be involved in the coming studies of the green ferry concept ferry as well.

corvusOn a partner meeting at the Danish headquarter of Siemens in Copenhagen two different systems for the ferry battery layout were discussed based on the tentative calculations of power consumption for a typically workday for the green vision ferry.

Global Account Manager Kim Strate Kiegstad from Siemens will be conducting the further analysis taking into consideration available power supply at berth, available time for recharge during working day and a detailed timeline distribution of power consumption throughout day and season. The partnership also has to make the strategic choice on required life cycle for the installed battery pack. This choice is of major importance to the needed size and price of the battery pack thus impacting the economy of the project directly.

The data is to be prepared by Naval Architect Jens Kristensen, Production Manager Henrik Frederiksen from Søby Værft, Project Coordinator Henrik Hagbarth Mikkelsen fromMarstal Navigationsskole and Area Director Søren Støvring-Hallsson from SE (Syd Energi). The solution will be based on known and well tested technology which is considered viable for the ferry size in scope. As known by many, Siemens is already the supplier of a retrofit battery solution for Scandlines' ferries in Denmark and in Norway Siemens has supplied the battery management solution for the first large scale fully electrical operated car and passenger ferry, expected to commence operation in 2015.

Schleswig-Holstein h lowScandlines has obtained subsidies of 48 million DKK from the European Commissions TEN-T (Trans-European Transport Network Executive Agency) for the conversion of their ferries between Germany and Denmark on Roedby-Puttgarden. The hybrid battery solution has already been installed on the first ferry Prinsesse Benedikte and the 2,7 MWh battery hybrid solution is considered the single largest installation on ship in the world. Siemens is supplying the Blue Drive Plus C system for the ferries. Read more...

battery packBased on the route model prepared by Naval Architect Jens Kristensen and Claus Bendix Nielsen and the preliminar CFD ferry layout, the first eastimate on needed energy consumption for the Green Vision ferry has been made. The estimates are within the expected range of the vision which indicates that the first barrier of creating a much more energy efficent ferry can be overcome.

The table of energy consumption on different routes has now been forwarded to the project partners at Siemens in Denmark in order to find and discuss solutions for possible battery layouts and go on evaluating different design choices and charging strategies.

Naval Architects Jens Kristensen and Claus Bendix Nielsen attended a work meeting with Naval Architect, Ph.D. Claus Daniel Simonsen, Force Technology and M.Sc.Eng. John Koch Nielsen from TINV/Force Technology. Their first layout had been forwarded in advance and was evaluated at a preliminary basis. Evaluation was positive and it was decided to incorporate some minor adjustment and proceed the more detailed analysis of CFD (Computer Fluid Dynamics) calculations. The possibility of comparison to a catamaran layout for steaming at very low water depth was also discussed but remains unsolved at this stage.

bottom viewNaval Architects Jens Kristensen and Claus Bendix Nielsen has finished the first ferry layout optimising hull shape and ships structure in order to bring down both weight and water resistance. The layout is stilled based on a ferry with approximately 25-30 car capacity and a load of up to four trucks. Accomadation is situated at same level as car deck to obtain low weight and easy evacuation.

Also the Naval Architects have prepared a detailed model of the ferry routes to and from Aeroe in order to take into account variations in depth and interactions with seabed. This model will enable us to make comparisons to other or existing ship designs in a swift way invastigating the impact of water channels and e.g. extra dredging. The design of the first ferry layout is now taken to the next level of a more detailed evaluation in cooporation with Force Technology in Lyngby where the CFD-models can be examined against their vast database on tank model experiments.

Two partners, SIMAC and Marstal Navigationsskole, attended the conference on Maritime Safety Health and Environment (MSSM in Danish) in Nyborg at the days from 26th to 28th of August. At the conference several presentations were held on both new ferries and environmental issues and the conference programme allowed a good opportunity for networking. Especially the smaller Danish island ferries were strongly represented and contacts were made to several stakeholders.

Tuco superstructures

At wednesday the 21th of August CEO Jonas Pedersen presented his company and the production of carbon composite sections for marine use for a group of project partners. Jes Heinemann and Thomas Estrup from the commitee on sustainable energy, The minicipality of Aeroe, Signe Jensen from SIMAC, Henrik Hagbarth Mikkelsen from Marstal Navigationsskole and Naval Architect Jens Kristensen participated in the following work meeting defining the work process, identifying barriers and dicussing solutions and comming work.

At friday the 16th of August an inital meeting with Mads Wojtynka from Fyn Maritime Klynge/Innovirk was held at Søby Værft. Also CEO Roar Falkenberg from the yard and Bjarne Kock Christensen from Søby Skibselektro attended together with the coordinators Naval Architect Jens Kristensen and Henrik Hagbarth Mikkelsen, Marstal Navigationsskole. The setup of the future newbuilding programme was discussed togehter with synergies to the maritime cluster of Fyn.

At tuesday the 13th of August an initial meeting was held at Syd Energi (SE), Aeroe, with area director Søren Støvring-Hallsson. Søren Støvring-Hallsson has more than 25 years of experience with renewable energy and the outline of the comming studies was discussed. Hopefully SE will be the supplier of the first solution for high performance charching of batteries for ferries in Denmark if the feasibility study proves efficient.

At friday the 9th of August CTO Kristian Ole Jakobsen from Esvagt visited Marstal Navigationsskole for a partner meeting on his experience with powerpacks and battery solutions for maritime use. Kristian Ole Jakobsen have been involved in projects both at Svitzer, Esvagt and Maersk. Strategy and pricing was discussed and the group got advice on experts to consult for newbuilding issues. Søby Værft, Søby Skibselektro, Naval Architect Jens Kristensen and Marstal Navigationsskole attended the informative meeting.

The work on the feasibility study has officially commenced today. The partners are already in the process of defining problem statements for the needed analyses in more detail according to the granted application for funding from Syddansk Vækstforum and the European Regional Development Fund.

The study is expected to be finished witnin a year and the working schedue leaves room for part deliveries, waypoints, that are published prior to the final report.

The feasibility study of the Green Ferry Vision has now been granted the applied funding of 412.000 DKK from Syddansk Vækstforum (European Regional Development Funding).

This means that the project can continue according to plan and further analysis will hopefully be conducted in near future. The following steps in the feasibility study are expected to be finished before August 2014.

During her visit at Aeroe on the 28th of June the Danish Minister of Business and Growth, Annette Vilhelmsen had a 45 minutes meeting with representatives from the Green Ferry Vision partnership. CEO Roar Falkenberg (Søby Shipyard), CEO Jonas Pedersen (Tuco Marine), Naval Architect Jens Kristensen, Principal Søren Vestergaard and project coordinator Henrik Hagbarth Mikkelsen both Marstal Navigationsskole attended the meeting.

The group had a good opportunity to promote the project and discuss the barrier identified. The Minister expressed enthusiasm for the nature of the project and the role of regulations and possibility of future funding were discussed briefly.

Three Danish islands have been the initiators of a new ferry analysis written by Jess Jessen-Klixbüll on ferry transport costs. The report will serve as documentation when future sbusidy regimes are to be discussed with the Danish Government.

betalingsringenThe report documents rising trends of fuel cost and other operation related cost resulting in expensive fares and capacity cuts. The analysis also include an estimate for introducing equality between road pricing and ferry pricing to and from the Danish islands.

A group of international students from Aalborg Univestity guested Aeroe in a brand new Renault Fluence Zero Emission at the 24th and 25th of April driving all the way (with some recharges). They were promoting their White Paper on electrical transport for Aeroe and Langeland. Local representatives from the partnership for the Green Ferry Vision participated in two meetings with the group. Renault

The group of students presentated a range of models and suggestions for financing the future transformation of island transport from dividends from public investments in an offshore wind farm south of Aeroe. Their ideas could be integrated as one of several financial alternatives in the planned feasibility study on the Green Ferry Vision.


Initiators from a local vision group for green ferries at Aeroe participates in a MARCOD conference on cost efficient green ferries in Middelfart, Denmark.

The seminar serves as a good basis for building up a professionel network. The participants are orientated about other ongoing projects and return home full of inspiration for further progress.

With the working title "Green Ferry Vision" a professional partnership of 12 companies and institututions have joined forces in order to create a concept for electrical powered zero emission ferries.

The partnership has set up a budget of 750.000 DKK for the feasibility study of their vision. Also the partnership has applied for funding from Syddansk Vækstforum under the European Regional Development Fund.

Partnership meeting at University of Southern Denmark compressedAmongst the professional partners are stakeholders with the geograhical centre of gravity at South Fyn and the Island of Aeroe which is also expected to be the target area for a future demonstration project.
