Battery storage maker Corvus Energy has been contracted to supply an energy storage system (ESS) to Norwegian Fjord1’s hybrid ferry Fannefjord.

The ESS comprises of 63 lithium polymer batteries with a capacity of 410kWh.

The ESS will be integrated with the existing Siemens drive system and be powered by two liquefied natural gas (LNG) generators.

According to Corvus Energy, the conversion of the LNG vessel to a battery hybrid will reduce methane slips and deliver further reduced greenhouse gas emissions, fuel efficiency and maintenance costs. The ferry currently features one diesel engine and two LNG-fuelled main engines.

The 123m Fannefjord has a capacity of 390 passengers and 125 cars.

Canadian-based Corvus Energy claimed that the ferry will be the world’s first LNG battery ferry on commercial routes.

The company recently announced that that its ESS has successfully achieved reductions in bunker consumption during a three-month trial at a hybrid passenger ferry operated by Norled/AS in Norway.

“This trial proves the Corvus energy storage product is an effective solution for modernisation of existing vessels, extending their usable lifespan and reducing costs for the operators,” said Sean Puchalski, vice president for business development at Corvus Energy.
