Maritime shipping is scrambling for decarbonization strategies mostly because regulations on ship operators are not strict enough. Early percentage-based carbon-emission reduction targets can typically be achieved by changing from bunker fuel to LNG (liquified natural gas), leaving the long-term solution still undecided. Ammonia has got the greatest potential but the industry seems set to go down the methanol route, as a steppingstone – perhaps unknowingly so. Methanol offers emissions reductions compared to bunker fuel due to its lower carbon content, reduced particulate matter, minimal sulfur, and lower nitrogen oxide emissions. Its cleaner combustion and potential for renewable production make it an environmentally favorable alternative for maritime transport. Ammonia provides further benefits due to the lack of a carbon atom in…
