How clean is NH3 as fuel?
Very clean. NH3 contains no carbon and if it is produced renewably using Freedom Fertilizer methods, the ammonia would be a 100% Co2 free fuel. Although research has shown that uncontrolled combustion of NH3 can produce some N0x emissions this can be easily corrected by controlling the oxygen rate at combustion and/or by a catalytic convert similar to what is used on all automobiles today.
