Review of Alternative Energy Resource for the Future Ship Power

In the near future, reduce emissions from the combustion of the ship's main engine by increasing the propulsion efficiency of ships that are already operating and/or optimizing ship designs during the design process. The International Maritime Organization (IMO) has introduced stringent regulations to reduce GHG emissions for the global shipping industry. Another solution to reduce emissions is to use alternative renewable energy and clean. This paper will describe what energy is used for ship propulsion nowadays and other alternative energy sources that can be used for main engines, additional or hybrid power. Wind energy, solar PV, and fuel cells are renewable energy options for small ships' main propulsion, navigation, lighting, and electronic devices. Furthermore, the method used for writing this paper is collecting the best paper and selecting technology alternatives energy that is possible to install on the ship.
