Another electric ferry is set to join the fleet of Västtrafik, the organization responsible for public transportation in the port city of Gothenburg, Sweden, running a route across the Gota Alv river in 2022. The battery-electric vessel is to be built by the Uudenkaupungin Työvene Oy shipyard.
Compared with her already operational sister vessel, Elvy, the new ferry will feature a larger energy storage system, supplied by EST-Floattech, with a total capacity of 1,260kWh and consisting of 120 individual modules. This should allow for between 7-8 hours of run time between charges and has also allowed for only a single generator to be installed on board, alongside smaller fuel tanks. The genset meets IMO Tier 3 emission regulations and will run on bio-diesel.
The ferry’s operators say the propulsion solution is expected to cut CO2 emission by more than 55%, with nitrogen oxides and particles emissions reduced by 40% compared with the sister vessels running on diesel electric power.
