Corvus Energy, Siemens and Fjord1 have announced the award of the contract for the 'Fannefjord' LNG hybrid ferry.
The refit 'Fannefjord' will use a 1,050-volt, 410kWh energy storage system (ESS) consisting of 63 Corvus Energy advanced lithium polymer batteries.
The ESS will be integrated with the existing Siemens drive systems and be powered by two LNG generators.
The 123-metre 'Fannefjord', a sister ship to the vessel 'Moldefjord', has a capacity of 390 passengers and 125 cars or 12 road trailers and 55 cars.
Typically, LNG diesel-electric ferries of this design feature one diesel engine and two LNG-fuelled main engines. The conversion of the already efficient and clean LNG ferry to a battery hybrid form will reduce "methane slip" and deliver even further reduced greenhouse gas emissions, fuel efficiency, improved maintenance costs and optimised engine performance, said Corvus Energy.
