The Department of Energy (DOE) spent $6.9 billion attempting to demonstrate the feasibility of CCS, unsuccessfully, between 2005 and 2012. Here is an example of one of their projects:
If you could wave away the laws of thermodynamics, you could do air or sea CO2 capture, release the O2 back into the atmosphere, and use the black carbon as a soil amendment. Caveats: 1. Of course this process would require more energy than you first obtained from burning your fuels. 2. Every time you disturb soils you release CO2, methane, etc. 3. transportation of the substances is required.
You don't want to live anywhere near a CO2 storage cavity if/when it "burps." You die.
The notion of doing some kind of CO2 sequestration and then selling an offset so that someone else can continue burning is extreme madness. At present, we need BOTH the end of emissions AS WELL AS negative emissions. Forget about 1.5 or 2 degrees of warming, we now have enough CO2 in the atmosphere to give ten degrees of warming, except that for now, aerosols are mitigating about 8 degrees of that. And, with ANY CO2 removal system (if it ever works), the oxygen MUST be returned to the atmosphere!! We MUST learn to get by using less energy!

This link also calls out CCS

The idea of storing CO2 in caverns is the Earth is pure farce.
Sereral huge issues here.
