Summary of ELMAR’s seminar during the 27th REGWA online symposium in Stralsund

The IRES Institute of Renewable Energy Systems at the University of Applied Sciences Stralsund hosted the 27th REGWA Energy Symposium from November 4th to 6th, 2020. Due to the current Covid-19 epidemic situation, the conference was held as an online event.

Wednesday 4th November, the first day of the event was dedicated to the South Baltic Interreg project ‘ELMAR’ Seminar dealing with e-mobility. The seminar was opened by Mr M. Heinrich representing Lead Partner - Economic Development Corporation Vorpommern. Subsequently three sessions followed.

The first session’s topic was “Market potential for electric propulsion in the South Baltic” with the following lectures:

  • The first one held by Harald Arndt from Neptun Ship Design focused on the market of marine electric propulsion in Germany based on the company’s own analysis.
  • Later Mr K. Tomczuk of Electrotechnical Institute Warsaw, Poland presented the current state of the fleet in Gdańsk Bay and Tricity region and its possible potential to apply hybrid drive systems on boats and jets operating as water public transport.
  • Thereafter Mr V. Djackov of Klajpeda University gave a lecture about ferry traffic on the Curonian Lagoon in Lithuania. Here the potential of the Curonian region for transformation from conventional to electric propulsion on water was in focus.

After a break the second session started. It’s main theme was ‘Electric passenger ships and the charging infrastructure requirements’.

  • The first lecture by Mr V. Djacko  concentrated on the results of the segment study on electric short distance passenger vessels in Lithuania.
  • Then Mr H. Gawiński from Electrotechnical Institute Warsaw gave a lecture on the state of the art of battery charging infrastructure. He explained dynamic charging power distribution and spoke about the interrelationships between the electricity grid and battery storage as well as maintenance in the off-season..
  • At the end of the session Prof. J. Gulden from University of Applied Sciences in Stralsund, presented the results of the study on charging infrastructure requirements on the coasts of Mecklenburg-Vorpommern.

In the late afternoon the third session ended with the topic Electric demo boats’ .

  • First Mr Evaldas from Green Boats in Lithuania showed a “making-of” video documenting the assembly process of an electric demo boat in Klaipeda and presented the technical performance of the electric motor of this water vehicle.
  • Finally a use case of an electric demo boat being built in Szczecin was presented by Mr F. Gruszczński from Yacht Technology Association in Poland. of particular interest was the implementation of a self-service rental system for an electric boat in the Szczecin Lagoon.


The seminar was an opportunity for the ELMAR project partners from Germany, Poland and Lithuania to present the most important project results to a wider audience of ca. 40 participants.

Different aspects of maritime e-mobility could be discussed, ranging from market and potential analysis for electrical propulsion system for small boats and larger passenger vessels to charging infrastructure demands in the South Baltic Region, namely Vorpommern (Germany), Tricity – Gdansk Bay (Poland) and Curonian /Klajpeda (Lithuania). The evaluation and demonstration of the pilot e-boatbuilding processes that have been realised gave insight into the technical requirements and lessons learned.
