Ouagadougou passenger ferry ship energy storage

Which energy sources are infeasible for shipping?

Based on the figure, it is evident that batteries and hydrogen are infeasible as the primary energy sources for the majority of shipping. Most of the potential alternative fuels occupy the middle region of the graph, just below 20 MJ/l. Figure 5.1. Comparison of volumetric energy densities and fuel tank sizes of emerging fuels and NMC batteries.

Why do ship fuels have a high volumetric energy density?

One of the most important properties of ship fuels is their volumetric energy density. A higher volumetric energy density allows a ship to operate longer without bunkering and thus generate more profits. Fig. 5.1 demonstrates this energy density for a variety of selected fuels.

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.

How much power does a 14000 TEU container ship need?

Consider a 14000 teu New Panamax container ship, a common size in trans-oceanic shipping. The power required to propel the ship at a design speed of 21.5 knots is 40.09 MW . At a reduced slow steaming speed of 16 knots, the required power is 16.38 MW assuming a cubic power curve for frictional resistance.

Can thermal energy be used in maritime transport?

In fact, the deployment of TES in maritime transport may be justified in a limited type of ships, like cruises, where even during hoteling (or staying on port) periods the thermal energy consumption is still remarkable. In fact, TES was conceived to balance the mismatch between energy demand and production periods.

What type of storage principle should a ship use?

That may define the type of storage principle to select: sensible or latent heat, or thermochemical. Obviously, in a ship the objective is to minimize the system size.
