Navigating towards Net-Zero: Exploring Alternative Fuels and Propulsion Systems for Decarbonising Maritime Transport

Abstract

Decarbonising maritime transport is required to be the main goal of the global stakeholders as around 90% of the global trade practices is carried through this mode. To accelerate the decarbonising process nations around the world have pledged and set their net-zero targets by the end of the year 2050 under the UN’s 13th SDGs. This research aims to understand net-zero’s relevance in decarbonising the maritime transport industry along with the exploration of alternative fuels and propulsions. The method that has been used here for the collection of data is secondary data while its analysis has been carried out with the help of thematic analysis. The findings of this research article have revealed that net zero is important for maritime operations due to heavy maritime fossil fuel emissions. The alternative fuels that can be taken in use include methanol-based fuel, ammonia-based fuel, and hydrogen-based fuels. When it comes to the propulsion system the best propulsion system could be the nuclear-powered propulsion. Finally, the implementation of these practices comes with several challenges which include political challenges, challenges regarding geopolitical tensions, and challenges due to lack of investments.
