Scandlines

Canadian Energy Storage Systems manufacturer Corvus Energy and Siemens have been awarded a contract to supply lithium energy storage systems to hybrid passenger ferries.

German-Danish ferry operator’s Scandlines agreed to have its M/V Berlin and M/V Copenhagen ferries fitted with a 1,050VDC, 1.5MWh ESS built from 231 Corvus Energy AT6500 advanced lithium polymer batteries.

The batteries will be used alongside a Siemens converter system and powered by four diesel gensets.

The AT6500 Lithium Polymer battery will provide 6.5kWh of energy in a ~2.5 cubic foot volume. Weighing 65kg, it is available in 12V, 24V, 48V and 96V configurations.

The hybrid propulsion system will also be equipped with a scrubber to clean the engines of exhaust streams of pollutants, which - according to a statement from Corvus - is expected to reduce sulphur emissions by “at least 90%.”

“The M/V Berlin and M/V Copenhagen are examples of the significant benefits both operationally and environmentally of battery hybrid propulsion,” Andrew Morden, President and CEO of Corvus Energy said.

The ferries will have a similar system to the ESS Corvus and Siemens delivered to the hybrid vessels currently operating on Scandlines’ Puttgarden-Rødby route.

Each ferry will have the capacity to carry 1,300 passengers and 460 cars or 96 trucks.
