What is a hybrid marine system? A hybrid system on a ship combines an energy storage system – a vessel battery - and a conventional engine. Its foremost benefit is that it allows the engine to run on optimal load because the battery will absorb many of the load fluctuations and acts as spinning reserve. This saves fuel and reduces GHG emissions.

Since the battery technology has low energy density so that it is not suitable for large ocean-going vessels as their propulsion energy sources. As such, this paper has established a ship boundary line of 1800 DWT or less and of five representative merchant ship types: tankers, containers, passenger ships, gas ships and bulk carriers.
Those load increases are compensated for with energy from the batteries. The battery-powered propulsion system integrates the Corvus Orca energy storage system (ESS) with 610 kWh capacity. Aurora Spirit's sea trials confirmed that its batteries offset the load on the engines .
Mass and volume limitations of the ship are monitored, and emerging opportunity costs are quantified in addition to capital and operating expenses. The application of battery-electric propulsion systems is found not to be limited by the vessel size but mostly by the operated passage length.
Currently, for shipboard propulsion, Li-ion batteries offer the highest energy density, a suitable power density, high efficiency and an acceptable lifetime.
