It's more efficient to use fossile fuels directly as every step has losses.

That's one of the reasons why I am mostly unfavorable to the SCR system, not only due to the diminished efficiency of the urea production but also because it doesn't lead to an actual improvement of the combustion process. At least one trucking company in my country performed tests with an Euro-3 Mercedes-Benz Atego fitted with a Diesel-CNG dual-fuel setup, and it ran cleaner than its Euro-5 equivalent fitted with SCR and DPF.
