Skopje ship energy storage technical requirements

How is the capacity of the storage tank optimized?

The capacity of the storage tank was optimized based on the distribution of the energy demand of the auxiliary systems during the port stays of the ship, evaluated during the 31 months of measurements ( Fig. 5.12 ). From this data, the estimated amount of thermal energy required in port between 200 and 300 GJ.

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 storage be used on ships?

Implementation of thermal energy storage on ships Thermal energy storage technologies have been applied in many other fields, where balancing of mismatch between energy production and demand is required.

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.

Can a cold thermal energy storage system be integrated in an all-electric ship?

A 1D numerical model to evaluate the integration of a cold thermal energy storage (CTES) system in an all-electric ship is presented by Yang et al. . The mathematical model considers a PCM as storage media but taking into account a limited number of parameters in its equations.

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.
