Ammonia as Fuel for Transportation to Mitigate Zero Carbon Impact

The idea of using ammonia as fuel is nothing new the first well-known Belgium use buses fleet during World War II. Even if several studies performed mid-60’s investigated possibility to consider for internal combustion engines, mainly by means CFR experiments or 0D modelling, ammonia-based engine fueling methods are not ready be marketed this toxic molecule still poses major problems only because supply and safety issues but also its physical characteristics compared conventional fuels. As function target, i.e. either partially in standard engines limit carbon footprint employ it dedicated reach zero footprint, technological challenges (dual unique fuel, SI CI …) could different main power auxiliary unit (to extend battery vehicles) a transportation type (mean duty heavy freight, construction, marine transportation, …). In chapter results advanced researches will discussed order highlight potential future green fuel.
