In comparison to hydrogen, liquefied ammonia makes it easier to transport large volumes to wherever it is needed. In the integrated process, it is possible to achieve an efficiency of 90% in comparison to 70% achieved with conventional technologies. This is particularly important for mobile and space-constrained applications.

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. urea-water solution—is injected into the exhaust stream and ideally decomposes to form ammonia, which reacts with NO x on the SCR catalyst to form N 2 and H 2 O. DEF—a 32.5

On the other hand, however, the lower exhaust gas temperatures result in a lack of energy for their propulsion on the exhaust side. Comparison of turbocharging systems. For clean combustion of hydrogen, the turbochargers have to, on the one hand, provide around twice as much air mass as they do in gasoline engines.
