Fuel cell technology Who: Corvus Energy What: Corvus’ Titan Lithium Battery is based on the 8D format widely used in marine applications, and is suitable for heavy start loads, heavy thrusters and short-term machineries, emergency electronics and as a back-up power source. It is an excellent option for hybrid or pure electric drive supply because of the robustness of lithium, and the company claims a 75% saving in tugs, although the carbon reduction will depend on how the electricity that charges the battery is generated.

Propulsion optimization sensor Who: Decision3 What: Greensteam is an onboard sensor that measures the relationship between a vessel’s speed and power consumption for propulsion to ensure its position in the water is optimized. This data is used to ensure the optimal settings of controls are being used under various loading conditions. It reacts dynamically to changes in the ship’s condition and environment, continually giving new settings for trim and propeller RPM through a data feed to a user interface on the bridge, achieving savings of 2.5% in one test.
