Rolls-Royce launched a lithium-ion-based energy storage system called SAVe Energy to increase efficiency for small ships and tug vessels.
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.
Rolls-Royce always seems to be at the top of their game when it comes to innovation. In the past, they also had rolled out plans for Autonomous Ships.
According to Rolls Royce, autonomous Ships will save on costs, weight and space – with the removal of crew accommodation and decks – thereby enabling the ship to carry more containers. Rolls Royce imagines that an on land crew equipped with smart sensors, cameras and drones will control multiple ships at the same time.
It will also rely heavily on AI to ensure intuitive predictability and situation awareness – enabling the ships to navigate tight spots and hazardous situations.
