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.

Battery storage maker Corvus Energy is to supply an energy storage system (ESS) to Spanish shipyard LaNaval for the production of a hybrid compressed natural gas (CNG) ferry.

The ESS comprises 48V lithium-ion battery modules with 1.6MWh capacity. The ESS will be used for backup power and aims to increase the energy efficiency of the ferry. The ESS can also be used to provide power-up and power-down capabilities.
