Economics with or without carbon externalities internalized via a carbon fee?

One is like saying "it's cheaper if I dump my pollution in this river than using your new tech" and one is like saying "even after cleaning the output so thats its pure water and disposing of it properly to the same degree as your new tech, I'd still be making money doing the old tech plus cleanup".

Any alternative must use renewable energy. The question is whether that should be used to produce hydrogen or synfuel kerosene.
