No it's not. In fact, it's impossible. Turning C02 into other stuff takes energy. There's no perpetual motion machine you can use to burn carbon, turn the carbon back into oil, and gain energy. It's impossible. The only solution is to reduce our demand for fossil fuels, and increase our excess energy generation enough that we can begin undoing the past 100 years of damage through capture after we've already prevented worsening of the problem.
Nowhere did I say or imply that capturing CO2 is a net positive of energy. It is in fact a huge energy sink. If you aren't using renewables to power CO2 capture then you're just making the problem worse.
