When looking at alternative fuels, there are several options. After careful consideration of the options and their related limitations, we concluded that the most suitable ánd future-proof fuel in this case study, is bio-methanol. Its properties make it suitable for a low-carbon economy and for a ferry with a fixed route (bunkering). The logistics are easy to set up in the Wadden Sea and, compared to Hydrogen, it is readily available and usable.
With bio-methanol, emissions are largely reduced and, unlike LNG, it can reach CO2 neutrality when it’s from a biomass source or synthetically produced with renewable energy. Finally, bio-methanol is safe for the sea environment and marine life. However, methanol is a low-flashpoint fuel and therefore subject to additional safety regulations for low-flashpoint fuels and gases.
