Emissions-cutting battery system

Used with an LNG or diesel-powered engine in a hybrid solution, Rolls-Royce’s liquid cooled SAVe Energy can reduce emissions at sea or in port. With a modular design that enables it to scale according to energy and power requirements, it can be coupled with most types of propulsion units.

Andreas Seth, Rolls-Royce, EVP electrical, automation and control – commercial marine, said: “The electrification of ships is building momentum. 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.”

Peak load control

In a hybrid set up, SAVe Energy handles the peak load, while the main power generators will relate to the average load and not reduce the propulsion units thrusting capabilities. As well as battery-powered vessels, SAVe Energy can be applied to peak shaving and spinning reserve.

SAVe Energy will be delivered from the Rolls-Royce Power Electric site in Bergen, Norway and is currently being introduce on Rolls-Royce’s current projects including the upgrade programme for Hurtigruten’s cruise ferries, the advanced fishing vessel recently ordered by Prestfjord and the ongoing retrofits of offshore support vessels, confirmed Mr Seth.

The development work has been partly funded by the Norwegian Research Council of Norway’s ENERGIX program. Color Line, Norled and the Norwegian Coastal Administration Shipping Company have also been partners in the development.
