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,” Rosvold further said.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.Two of the vessels will be built by Turkish shipbuilder Tersan and the remaining by Spanish Barreras. Featuring a length of 125 meters and a width of 20 meters, the ships will be able to accommodate 700 passengers.The vessels will have a hybrid gas-electric propulsion system with battery, 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.The equipment from Corvus Energy is scheduled for delivery in 2020 and the coastal route vessels will be in service from 2021.
