energy storage system to meet the charging demands of an all-electric ship (AES). The technology was evaluated based on recharging batteries. When compared to a diesel ship, the AES showed savings of 5,6 27,293liters of diesel/yr and a reduction of 19,823 tonnes of CO.
A reasonably sized on-board battery could be charged fully with the ship's main engines during cruising, and then depleted to supply hotel load during port operations. Such methods, coupled with supplying the hotel load from a shore connection, would have a major impact in reducing local emissions in harbors.

Th is paper presents review of recent studies of propulsion vessels. It also reviews several types of energy storage and battery management systems used for ships’ hybrid propulsion.
However, there are certain auxiliary tasks where batteries can be utilized to improve the overall efficiency of a ship's energy system, even if the batteries capacity is small compared to the total output capacity of the energy system.
The current battery energy storage systems on board vessels are based on a monotype topology, where a single type of battery provides the total energy and power required for the vessel. Depending on the application, the battery technology in the monotype systems is either a high-power (HP) or a high-energy (HE) cell type.
One solution could be to replace the source of power from diesel to electricity stored in batteries during port stays. Moored vessels in harbor retain a portion of their power production for needs such as heating, lighting and ventilation. However, the magnitude of this hotel load is considerably smaller compared to that needed for propulsion.
