No, this is incorrect. You can absolutely burn hydrocarbons, use the energy to do carbon capture, and end up with less CO2 in the air than when you started.
Compressed CO2 is still a lower energy state than the hydrocarbons, so you can get net energy out.
You couldn't end up with the same hydrocarbon that you started with, of course - that would violate the laws of thermodynamics.
- blkhawk 3y agoThere is no place to store all that - and don't say depleted gas and oil wells since those are ruined as long term storage by whats been done to them to get the oil or gas out. So you need to build the structures to keep 20km³ of liquefied CO2 each year (liquefying also takes energy).
