All of the carbon we put in the atmosphere was transported (oil, coal, etc) to the location where it was used so this rings false. Presumably the carbon will be pulled from the atmosphere on site and stored on site anyway.

Maybe something like building solar arrays in semi-arid regions and mixing up the resulting solid carbon into the local soil for some ecological engineering or filling up old mining pits.

The carbon gains 2 oxygens when combusted, tripling the weight of the original fuel

Presumably it also loses 2 oxygens when it is turned back into solid carbon.
