The high cost of Lithium-ion battery systems is one of the biggest challenges hindering the wide adoption of electric vessels. For some marine applications, battery systems based on the current monotype
Energy storage systems (ESS) integration is a key point for hybrid ships. On a first hand, integration of ESS allows an internal combustion engine to be operated at the most efficient range to minimize fuel consumption and so harmful emissions.
New energy sources, including solar energy, wind energy and fuel cells have already been introduced into ship power system. Solar energy can now be used as the main power source to propel small-scale ships, and as an auxiliary power source in large-scale ships to supply lighting, communication devices and navigation system.
4.1.1. Solar/battery powered ships Solar/battery power system is the typical power system configuration for medium and small-scale solar-powered ships. The “Sun 21” (Fig. 9 a) was the world's first solar-powered ship to cross the Atlantic in 2006, with 65 m 2 PV panels between the hull to supply the ship power system .
The main purpose of electric storage is to supply energy when the power demand is maximized and to allow a diesel engine to work at efficient engine loads. Renewable energy can be used in OSVs to charge ESSs such as batteries, supercapacitors, or flywheels. Table 6. System assessment according to ship types.
The energy storage system can give UPS like functionality for all or portions of a power system. Energy storage system interacts with the power system to optimize engine fuel efficiency. It is charged and discharged so that power is only generated at peak efficiency and lowest cost, optimizing the operating point of online generators.
The integration of new energy sources into traditional ship power systems has enormous potential to bring the shipping industry in line with international regulatory requirements and is set to become a key focus of ship-related researches in the immediate future. 1. Introduction
