Rolls-Royce introduces lithium-ion battery system for ships

17 Aug 2018

Engineering firm Rolls-Royce is launching SAVe Energy, a lithium-ion based energy storage system for ships.

SAVe Energy is 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.

The battery system also complies with international legislations for low and zero emission propulsion systems.

The system’s development work has been partly funded by the Norwegian Research Council of Norway’s ENERGIX program.

The three ship owning companies Color Line, Norled and the Norwegian Coastal Administration Shipping Company have been partners in the development, trialling the energy storage system on a wide variety of marine applications, including ferries, cruise vessels and multi-purpose vessels.

“The electrification of ships is building momentum,” says Andreas Seth, Rolls-Royce, EVP Electrical, Automation and Control – Commercial Marine.

“From 2010 we have 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.”

According to Seth, battery systems have become a “key component” of Rolls-Royce’s power and propulsions systems, and SAVe Energy is being introduced on many of the projects the company is currently working on.

“This includes the upgrade programme for Hurtigruten’s cruise ferries, the advanced fishing vessel recently ordered by Prestfjord and the ongoing retrofits of offshore support vessels,” he shares.

“As a system provider we can find the best solution considering both installation and operational cost.”

SAVe Energy is an ESU system (Energy Storage Unit), and was recently class approved by DNV GL, and is accepted for installation on all vessels classed by DNV GL.
