Rolls-Royce Unveils Green Shipping Innovation


Rolls-Royce has launched a lithium-ion-based energy storage system called SAVe Energy to increase efficiency for small ships and tug vessels.

Rolls Royce has found that SAVe Energy’s modular design allows it to scale according to energy and power requirements.

An LNG or diesel-powered engine can be combined with the system, as well as most types of propulsion units to form a hybrid set-up.  

SAVe Energy will handle the peak load, while a vessel’s main power generators will not reduce the propulsion units’ thrusting capabilities. 

It can be applied to several areas, including peak shaving, spinning reserve and battery-powered vessels

The SAVE Energy project, which is partly funded by the Norwegian Research Council of Norway’s ENERGIX programme, as well as ship-owning companies Color Line, Norled and the Norwegian Coastal Administration Shipping Company, is another step towards the maritime sector preparing for the International Maritime Organisation’s (IMO) 2020 emissions rules.

On August 17, Norwegian logistics company Kongsberg Maritime announced an agreement with Nanjing Jinling Shipyard to deliver power and hybrid systems to nine roll-on roll-off vessels.
