> need carbon collection on all combustion engine
why not simply centralize the carbon collection and synthesis in some area (preferably where the sun shines a lot), then pipe/transport the resulting hydrocarbon fuel to where it is needed?

On the other hand, the output of a methane-powered fuel cell is 33% CO2 and 66% H2O - with the water being rather trivial to filter out. Even a dirty regular combustion engine outputs about 14% CO2.
