World's First "Supercharged" Battery-Powered Ferry to Serve Stockholm

Thursday May 1, 2014

A battery-powered ferry is set to start operations on a Stockholm inner-city route by August, Echandia Marine, the Swedish company that developed the ferry's propulsion system, said in an emailed statement.

The 100-passenger ferry, Movitz, is being retrofitted with nickel-metal-hydrid (NiMH) 180 kWh batteries and two 125 kW electric motors placed outside the hull.

The ferry will be able to be "supercharged" in 10 minutes, while passengers embark and disembark, and then operate for an hour.

The vessel will be operated by Sweden's Green City Ferries and will run from Solna Strand to Gamla Stan in Stockholm's Old Town.

Echandia said the propulsion system, supported by the Swedish Energy Agency, could be used in new vessels as well as retrofits.

With the retrofit, Movitz will replace a 250kW engine that burned 50 cubic meters of diesel per year, eliminating emissions of 130 tonnes of carbon dioxide (CO2), 1.5 tonnes of nitrogen oxides (NOx) and 80 kilograms of particles.

DNV GL said in March that fully battery-powered ferries, as well as hybrid vessels are likely to gain ground over the next decade.
