Shipping emissions are a significant contributor to global air and greenhouse gas emissions. The shipping industry is responsible for emitting a variety of pollutants, including nitrogen oxide (NO2), sulfur oxide (SO2), carbon dioxide (CO2), and black carbon. These pollutants have a significant impact on the environment and human health.
In recent years, there have been increasing efforts to reduce emissions from ships. The International Maritime Organization (IMO) has implemented regulations aimed at reducing the emissions of pollutants from ships. These regulations include the use of low-sulfur fuels and the implementation of emission control areas.
A literature review of the changes in marine propulsion and fuels reveals that there is a growing interest in the use of alternative marine fuels. These fuels include liquified natural gas (LNG), biofuels, and hydrogen. These alternative fuels have the potential to significantly reduce emissions of greenhouse gases and air pollutants from ships.
Assumptions from studies based on greenhouse gas emissions suggest that the use of alternative marine fuels can lead to significant reductions in emissions. For example, the use of LNG as a marine fuel can lead to a reduction of up to 25% in CO2 emissions when compared to traditional marine fuels.
The impact of marine fuels on greenhouse gas emissions can also be evaluated by looking at tank to propeller emissions. This refers to the emissions that are produced from the extraction, production, and transportation of the fuel, as well as the emissions that are produced during the combustion of the fuel in the ship’s engines. The use of alternative marine fuels can lead to significant reductions in these emissions.
The impact of different marine fuels on the global warming potential (GWP) of fuels can also be evaluated. The use of alternative marine fuels can lead to a reduction in GWP, as well as a reduction in the total cost of transportation. This can have a positive impact on the world transport trade (WTT) and total transport costs (TTC).
The shipping industry is a significant contributor to global air and greenhouse gas emissions. Efforts to reduce emissions from ships, including the use of alternative marine fuels, have the potential to significantly reduce emissions of pollutants and greenhouse gases. Further research is needed to fully evaluate the impact of different marine fuels on emissions and the global warming potential of fuels. Based on this research, recommendations can be made to promote the use of alternative marine fuels in the shipping industry.
