Diesel generator sets: These are the most common type of emergency power supply for ships, as they are reliable and efficient. They can be run on diesel fuel, which is easily accessible and readily available.
Battery banks: Battery banks are typically used as backup power sources, providing power when the main power source fails. They can be charged by the ship’s generators or by solar panels, and are useful in providing a quick and easy source of power.
Fuel cells: Fuel cells are an emerging technology that uses a chemical reaction to generate electricity. They can be used as an alternative to diesel generators, providing a cleaner and more efficient source of power.
Shore power: In some cases, ships may be able to connect to shore power, which can provide a stable and reliable source of electricity. This is typically only possible when the ship is docked in port.
