Just from the energy levels of carbon (high, burns well) and carbon dioxide (low, inert gas) you can deduce, if there is an sequestration facility that is worth

  Nobody is claiming that removing carbon dioxide from the atmosphere is producing energy, it will always cost some energy. When we reached zero carbon dioxide emissions, then one can consider actively lowering the carbon dioxide level by pulling some out of the atmosphere. But until then it is essentially avoiding carbon dioxide emissions vs continuing them and then spending more money to undo them. In principle this could work, if avoiding emissions in one place was more expensive than undoing them in another place - if we only had really bad batteries, then it might make sense to keep combustion engines and capture the carbon dioxide in stationary facilities. In practice and at scale I neither see it necessary nor feasible.
