I don't even know why this is a question. So, people burn hydrocarbons for energy. How do you expect to capture the carbon piece into a stable compound that can be buried without expending more energy? Please draw this chemical reaction out, along with energy balances and how endothermic it is.
The idea that you could do this belies total ignorance of chemistry, fossil fuel genesis and the laws of thermodynamics. Life actually does a pretty good job of turning CO2 into dirt which gets buried -encouraging that rather than building some preposterous contraption involving mineshafts seems a little more sensible.
