Electric Operation Makes Ferries More Profitable

Description: Potential for pure battery-powered or hybrid ferries: As most ferries today operate on relatively short routes, they have operational profiles that mean pure battery power or hybrid solutions can be profitable. For longer routes, batteries with greater capacity are necessary, which incur higher costs of supercharging and make battery- powered solutions less competitive. Therefore it is economically and environmentally preferable to choose hybrid solutions for longer routes. Furthermore, it may also be economic to invest in a supercharger on the quayside for longer routes. Battery power is not viable for routes with low trip frequency, where reduced operating costs are too low to cover investment. Battery operation: Of 180 ferries in Norway, 84 have crossing times of less than 35 minutes and operate at least 20 trips on each of their 61 different routes during a 24-hour period. This operational profile makes battery-powered solutions profitable. Hybrid operation: 43 ferries operating on 32 routes have operational profiles that make hybrid solutions profitable. These hybrid solutions use a combination of battery power and either diesel- or gas-driven propulsion systems. Emission reduction potential: To calculate potential for reducing emissions, our study looks at the feasibility of replacing 127 of Norway’s ferries with either battery- powered (84) or hybrid alternatives (43). We then compare predicted emissions from the environmentally friendly vessels with 127 diesel- driven ferries. This comparison forms the basis for calculating emission reductions from battery-powered or hybrid ferries. The following environmental benefits are provided by 127 battery- powered or hybrid ferries: CO 2 emissions cut by 300,000 tonnes per year, Diesel consumption cut by 100,000 tonnes per year, NoX emissions cut by 8,000 tonnes per year.

ferries more profitable – a feasibility study

Introduction
In 2015, the world’s first battery-driven car ferry came
into service between Lavik and Oppedal on Sognefjord
in western Norway. Just on this one route, the Ampere
delivers significant savings in operational costs and
greenhouse gas emissions for the shipowner.
Today, there are a ... See more
