Rolls-Royce Holdings Plc has begun offering its own battery-powered ship engines in a move that signals the gathering momentum behind a push towards hybrid and ultimately all-electric vessels.
While maritime demand for lithium-ion batteries is focused on providing top-up power for traditional diesel and gas-turbine ships, the technology could propel fully electric craft over a limited range, according to Rolls, which previously sourced such equipment from third-party providers. Branded SAVe Energy, the new system will be delivered from the group’s marine arm in Bergen, Norway. In hybrid mode the batteries will kick in to provide additional propulsion on vessels spanning ferries to trawlers when a conventional engine is operating at peak thrust, Rolls said.
