Wind Propulsion
Wind propulsion assistance technologies have been considered in this paper as energy-saving technologies to reduce the demand of using fuel for propulsion. The use of renewable wind energy for ship propulsion – using sails – is an ancient technology, but its application to modern commercial vessels is novel.
Battery
Electrification enables energy-efficient and quiet propulsion. However, the investment case currently works only for specific ship operational profiles due to the low energy density and charging time requirements.
Fuel Cell
Fuel cell technology has been around a long time but has only recently become commercialized in the transport sector for road vehicles and for stationary power generation. In a fuel cell, electricity is produced by the oxidation of hydrogen with the emission of water vapour.
