Rolls-Royce announced that it is launching a lithium-ion based energy storage system for ships. The benefit for the operators would be a clean and cost-efficient complete system.
SAVe Energy is a liquid cooled battery system with a modular design that scales according to energy and power requirements. SAVe Energy complies 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 energy storage system covers a wide variety of marine applications, including ferries, cruise vessels and multi-purpose vessels.
SAVe Energy can also be applied to several areas such as peak shaving, spinning reserve and battery powered vessels. When combined with an LNG or diesel powered engine in a hybrid solution, it can increase efficiency and reduce emissions, while it can be coupled with most types of propulsion units. 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.
Andreas Seth, Rolls-Royce, EVP Electrical, Automation and Control – Commercial Marine, stated:
Battery systems have become a key component of our power and propulsions systems, and SAVe Energy is being introduced on many of the projects we are 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.
SAVe Energy is an ESU system (Energy Storage Unit). DNV GL has recently approved it, confirming that it complies with the newest 2018 ruleset, and can be installed on all vessels classed by DNV GL.
