The atmosphere there provides all the carbon, oxygen and nitrogen you need, hydrogen (from water) is the thing in short supply at present. If you can synthesize methane there, you should be able to make longer chains and polymers with the right application of chemistry. One thing for sure, you'd never just burn fuel/oxygen together instead of using fuel cells, batteries and solar. Nuclear would be a good power source if cooling isn't impractical.
