Abstract
One of the most important actors of maritime transport is cargo ships where cargo is transported. Nowadays, the expansion of the maritime trade volume with increasing acceleration, the increase in the size and quantity of ships in the world’s merchant navy fleet cause transportation costs to decrease per ton while to bring some negative effects such as air pollution. The major cause of ship-source air pollution is the conventional fuel used in propulsion systems. As of 2006, serious steps are being taken in the context of air pollution prevention measures that have been on the agenda in the sector on a global scale. In this study, recent academic literature conducted on this subject reviewed in recent years, renewable energy and other fuel types that can be used in efficiency equivalent to conventional fuel were evaluated. As a result of this thematic review, although the ship projects carried out with renewable energy in the project phase are exciting, the most powerful alternative in the short term seems liquefied natural gas (LNG) which is not accepted as renewable but found to be successful in terms of emissions. It can be used in ships with tonnage nearby coastal voyages, while in the offshore vessels which constitute the main emission problem; renewable energy is evaluated within the scope of additional measures that increase efficiency in the short term. In addition, as a fuel alternative, hydrogen is a candidate for future ship fuel in the medium and long term.
