Ammonia as Maritime Fuel
www.energy.govused in Selective Catalytic Reduction (SCR) systems for decades • As a cargo, there are established safe handling procedures • Its use as a fuel will nearly eliminate particulate matter and black carbon emissions, and CO2 if produced using renewables • Can be used by both internal combustion engines and fuel cells, potential for retrofits of
An industrial view of ammonia as a marine fuel
www.topsoe.comammonia 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
