Are lithium-ion batteries a viable energy source for ferries?

Lithium-ion batteries have been recently installed onboard smaller scale ferries and passenger vessels either as the primary energy source, or then as a hybrid solution. Various lithium-ion battery chemistries are available, with sources pointing at lithium nickel manganese cobalt oxide as the most feasible solution for ships.

Can a moored ship be powered by a battery?

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.

Can batteries improve the efficiency of a ship's energy system?

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.

Which battery chemistries are suitable for ship energy systems?

Battery characteristics Battery chemistries suitable for ship energy systems are primarily lithium based.

Can a ship's battery be used to supply hotel load?

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.

How do ships use thermal energy?

Given the space that thermal energy storage systems may occupy aboard a ship, tugs would be the most likely vessels to operate on stored thermal energy, moving ships around harbors and/or pushing and navigating barges on short coastal voyages or along inland waterways.
