Decarbonizing the Bay of Kotor: Preliminary Electrification Concept of a Ferry

Abstract

International Maritime Organization (IMO) and regional authorities have been gradually introducing decarbonization policies and regulations. Shipping sector’s primary response remains the reduction of the cruising speed. Other solutions can include hull optimization, application of energy saving devices, alternative fuels. Alternative fuels are still under the development and could significantly reduce emissions, through the application of batteries, hydrogen, ammonia, etc. However, domestic voyages by ferries have not been exposed to the regulations’ scrutiny. Nevertheless, in the regions such as the Bay of Kotor (Montenegro), protected by UNESCO, maritime transport is expected to follow environmental policies. In order to encourage the decarbonization of such regions, this paper offers a preliminary concept solution of an electric ferry for the Bay of Kotor with reduced onboard emissions. The concept is based on available data on the most energy demanding ferry in Bay of Kotor that has operated for the past decade. The ferry follows the short route suitable for the application of electric drive. Analysis of an operational profile and the ferry concept design parameters are presented, as well as the advantages and disadvantages of electric ferry proposal.
