Yes, but wouldn’t it be better to simply replace dirty power generation with this new renewable electricity rather than expending all of the renewable power on this hypothetical CO2 extraction facility. At some point, I suppose, the overall carbon footprint of our world’s electrical generation will come down to the point where CO2 extraction will be a net win. Right now it’s not clear to me.

We need the fastest path to net zero including things like cement and ships and long-haul jets and agriculture, and all that adds up to more than our emissions from electricity. Fastest path probably includes getting a head start on negative emissions.
