Havila Kystruten has confirmed it will install the world’s largest battery pack on-board its coastal vessels. A contract has been signed between Corvus Energy and Norwegian Electric Systems (NES) to deliver and integrate the battery pack on-board the Havila vessels.
Corvus Energy will deliver an air-cooled energy storage system (ESS) with Corvus’ patented single-cell thermal isolation, exceeding class requirements to ensure the highest level of safety. The ESS has a capacity per vessel of 6,100 kWh, double the capacity of any existing battery-operated ferries, according to Roger Rosvold, vice president sales, Corvus Energy.
The battery pack will allow the ships to operate with zero emissions in environmentally sensitive areas.
“The unused potential for using batteries on board cruise and passenger ferries is huge. Batteries reduce fuel consumption and maintenance costs, cut pollution and, with increasing environmental regulations and requirements that will incur costs for air emissions, provide a very compelling business case. As more and more shipowners wake up to this, we expect to see uptake accelerating across the board. The industry is just starting to understand the power of batteries,” says Rosvold.
“This is a big step for the cruising industry and we are extremely proud to receive this order. It demonstrates that we drive technology further by pushing boundaries for the use of batteries. The ESS is the world’s largest package ever delivered to a ship and will enable the vessels to enter fjords and ECAs on zero emission mode five years before the deadline,” explains Geir Bjørkeli, CEO, Corvus Energy.
“There is no one-size-fits-all solution for batteries. You have to optimise and compromise to find the right balance between energy density, capacity, performance and lifecycle to ensure the most optimal ESS solution,” says Stein Ruben Larsen, senior vice president sales, NES.
“We chose Corvus Energy due to the proven reliability, safety and performance of the Corvus ESS, in addition to their experience and the high level of technical support provided through previous project deliveries to NES. We know we are getting the best ESS available in the market.”
The newbuilds are part of Havila’s contract with Norwegian Ministry of Transport for the construction of four environmentally-friendly vessels that will operate on the Bergen-Kirkenes coastal route. The vessels will feature hybrid gas-electric propulsion systems with batteries, where four gas-powered engines in each vessel run the generators. The system is also adapted to the next generation of technology, using hydrogen fuel cells.
Two of the vessels will be built by Turkish shipbuilder Tersan and the remaining by Spanish Barreras. The equipment from Corvus Energy is scheduled for delivery in 2020 and the coastal route vessels will be in service from 2021.
