Ammonia as fuel for shipping: challenges and opportunities
Ammonia is a hydrogen based fuel that can be used in certain fuel cells or as a fuel for direct combustion in internal combustion engines. According to the Hydrogen Europe comparison tool, it is considered a very promising option mainly for larger ships but there are still many issues to tackle. Ammonia is an interesting case among the e-fuels options not only because it is the only fuel that doesn’t contain carbon but also because it is already produced globally in large volumes, which could accelerate the transition of shipping towards decarbonization.
