BOSTON, Dec. 9, 2022 /PRNewswire/ — It is becoming prosaic to say there is no ‘silver bullet’ for marine decarbonization. But it might be fitting to say ‘multiple silver bullets’ are emerging since between batteries, fuel cells (FC), green hydrogen, green ammonia, e-methane and carbon capture, decarbonization across all marine subsegments might just be possible. IDTechEx sees green fuels as one of the most promising solutions to decarbonize large sea-going vessels.

The chemical energy held in green fuels can be converted into mechanical energy in multiple ways, including combustion; however, fuel cells have high potential as a highly efficient solution offering a pathway to zero emissions. Currently, there are only two options for fuel cells in the marine environment – proton…
