Energy harvested from harbor systems: several publications deal with harvestable energy from quay cranes [23,49,50] and gantry cranes [21,28,42,51,52,63].
Energy storage, both in its electric and thermal forms, can be used both to transfer energy from shore to the ship (thus working similarly to a fuel) or to allow a better management of the onboard machinery and energy flows. This chapter is made of two main parts.
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.
The hybrid ship has two different types of power generators and two or more power consumers; and additionally, the battery can change from generating power to storing energy, i.e. it switches between being a power generator and a power consumer. This means that keeping the control system simple can be challenging.
This means that the entire ship can be supplied from shore, an d the large battery can also be charged by shore power. This will help eliminate the need of running the diesel engines while quayside. engine only in diesel–electric mode. The batt ery will deal the short-term increases in power demand, subsequently saving vast amounts of energy.
Our economic analysis takes into account the installation and fuel costs of both the conventional and hybrid systems. Due to the benefits of hybrid power generation, as well as the gains from regenerative braking of the cranes, we find that hybrid power generation for crane operation is highly profitable.
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.
