If you burn CO as fuel you are producing CO2 back.
It may be useful as fuel for a mars vehicle or for rockets (electric vehicles will take you not very far and it's hard to strap the nuclear reactor to it). CO is easier to store than hydrogen. Of course, if you have a steady supply of ice you can make methane/methanol which is better for that purpose. But to extract ice you will need heavy mining machinery, earth-moving etc... CO + O2 fuel would make more sense on Ve…
