An industrial view of ammonia as a marine fuel

ammonia combustion can be removed from exhaust gases with selective catalytic reduction (SCR) technology. This report shows that ammonia is not only an attractive long-term solution for carbon neutrality but also can have a strategic role in the transition phase. By shifting gradually from fossil-fuel based
