Rolls-Royce presents Li-ion battery for ships


Rolls-Royce is launching a lithium-ion based energy storage system for ships. This is the first time the British propulsion specialist will deliver batteries to fit their drives as such units were previously supplied by an external party. The SAVe Energy system is modular.

Said modular setup will enable Rolls-Royce to equip ships of varying sizes and power needs. Moreover, they will deliver everything in one go and out of their own house. This is a big step knows 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.”

SAVe Energy is to be delivered from the Rolls-Royce Power Electric site in Bergen, Norway, as part of the company’s offering of complete ship systems. Accordingly, the development has been partly funded by the Research Council of Norway’s ENERGIX programme. Rolls-Royce found other partners in the ship owning companies Color Line, Norled and the Norwegian Coastal Administration Shipping Company. They were ensuring that the energy storage system covers a wide variety of marine applications, including ferries, cruise ships and multi-purpose vessels.

SAVE Energy not only serves different types of ships but can also apply to different purposes, i.e. zero emission idling, peak shaving, or entirely electrically-powered vessels.

As Rolls-Royce has been working on various marine applications with varying degrees of electrification, they will apply their proprietary system from now on. Says Seth: “SAVe Energy is being introduced on many of the projects we are currently working on.”

This includes the upgrade of Hurtigruten’s cruise ferries in order to make them hybrid. Rolls-Royce agreed to deliver the hybrid system for six cruise ships with the Norwegian firm holding an option for another three vessels.

SAVe Energy complies with international legislations for low- and zero-emission propulsion systems.
