Energy Storage System Ordered for LNG Battery Hybrid Ferry

Norwegian hybrid to be the first LNG battery ferry to operate on commercial routes

Corvus Energy, Siemens AS and Fjord1 have announced the award of the contract for the Fannefjord LNG hybrid ferry. The refit Fannefjord will use a 1,050V, 410kWh Energy Storage System (ESS) consisting of 63 Corvus Energy AT6500 advanced lithium polymer batteries. The ESS will be integrated with the existing Siemens drive systems and be powered by two LNG generators. 

The 123m Fannefjord, sister ship to the vessel Moldefjord (who won the 2010 Green Ship of the Year), 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 optimized engine performance.

Sean Puchalski, Vice President Business Development, Corvus Energy, said, “Based on our research, the Fannefjord will be the world’s first LNG-battery hybrid ferry in operation.”
