Analysis of Exhaust Emission Reduction with Marine Fuel Additives

Abstract

The shipping industry and shipowners are facing challenges in reducing exhaust gas emissions while maintaining efficient fuel and energy consumption. In the maritime decarbonization process, the focus is on alternative marine fuels that have the potential to achieve sustainable and green shipping. However, their implementation process is not easy due to high cost, handling and storage complications, and availability issues. This research analyses additives in marine diesel fuels and their impact on the emission reduction process. The analysis focuses on a comparison between traditional additives and SulNOx marine additive, a fuel conditioner product that is relatively new to the maritime sector. The key benefits of SulNOx are emission reductions, an improved combustion process (more efficient combustion), lower fuel consumption, improved lubricity and reduced carbon deposits on cylinder liner and piston rings. A more efficient combustion process is achieved with the secondary atomization method due to the presence of glycol ether in the additive, which also reduces soot formation in the cylinder, resulting in reduced particulate matter emissions. In terms of economic aspects and energy efficiency, SulNOx's fuel savings could improve the Carbon Intensity Indicator (CII) of a ship and could reduce EU ETS costs. The average fuel savings and CO2 reduction in metric tons per year are presented with a simple calculator, where users can gain insight into how much savings they may achieve when using SulNOx.
