The purpose of this paper is to examine and analyse existing and future solutions regarding alternative fuels and the pollution reduction technologies and practices that can be used in shipping.
The alternative fuels considered are hydrogen, ammonia , methanol, the biofuel family and nuclear energy. The technologies considered for pollution reduction practices are fuel scrubbers and slow steaming.
The solutions considered bring alternative fuels and emission reduction technologies either directly into the ship's propulsion system (as a primary or auxiliary power source) or as a power supply for the ship's auxiliary systems.
Therefore, there is no single solution that fits all cases of carbonisation in the shipping sector, but different ones that can be applied on a case-by-case basis, depending on the cost of implementation, their potential for the future and the problems that arise during implementation.
Regulatory authorities such as the International Maritime Organisation (IMO) and the European Union turn targets into regulations. As mandatory carbon dioxide (CO2) regulations are strengthened, it is clear that no single fuel will solve all of shipping's zero-carbon needs. In the future, shipowners will equip ships for the fuel that is most suitable for the type of ship, route and cargo. In addition to ammonia, other alternative fuel candidates include hydrogen, methanol, biofuels, batteries and nuclear energy.
