LNG ferry to convert to hybrid power

The Fannefjord, operated by Norwegian company Fjord1, currently features a diesel electric propulsion system with two LNG-fuelled gensets and one diesel. With the new arrangement, the two LNG engines will supply power to a Corvus Energy 1,050V, 410kWh energy storage system (ESS) comprising 63 AT6500 advanced lithium polymer batteries. The ESS will be integrated with the existing Siemens drive systems.

The 123m Fannefjord has a capacity for 390 passengers and 125 cars or 12 road trailers and 55 cars. Corvus says that conversion of the already efficient and clean LNG ferry to a battery hybrid form will reduce methane slip and deliver further reduced greenhouse gas emissions, fuel-efficiency, improved maintenance costs and optimised engine performance.

“We are very pleased that Corvus’ energy storage system was selected for this innovative vessel,” said Sean Puchalski, vice president business development, Corvus Energy. “Based on our research, the Fannefjord will be the world’s first LNG-battery hybrid ferry in operation.”

Corvus adds that its lithium polymer energy storage technology provides the consistent power and reliability to support the specific performance attributes of LNG powered vessels.
