Modular battery targets electric ships

August 23, 2018 // By Christoph Hammerschmidt
Rolls-Royce is launching a lithium-ion based energy storage system for ships.

Energy storage is a major green investment for a ship owner. Returns are maximised when the system is correctly dimensioned for the specific ship and includes intelligent power control. Towards this end, Rolls-Royce now offers SAVe Energy, a cost competitive, highly efficient and liquid cooled battery system with a modular design that enables the product to scale according to energy and power requirements. SAVe Energy comply with international legislations for low and zero emission propulsion systems.

The development work has been partly funded by the Norwegian Research Council of Norway’s Energix program. The three ship operators Color Line, Norled and the Norwegian Coastal Administration Shipping Company have been partners in the development, ensuring that the energy storage system covers a wide variety of marine applications, including ferries, cruise vessels and multi-purpose vessels.

SAVe Energy is be delivered from the Rolls-Royce Power Electric site in Bergen, Norway, as part of the company’s offering of complete ship systems.

From Rolls-Royce’s perspective, the electrification of ships is building momentum. From 2010 the company has delivered battery systems representing about 15 MWh in total. “However now the potential deployment of our patent pending SAVe Energy in 2019 alone is 10-18 MWh”, said Andreas Seth from the company’s Commercial Marine branch.
