Long term, yes, that's exactly the plan. Short-term, it's going to be CO2 captured from large emission sites - powerplants, chemical processing industry, cement and steel factories etc.

Just because the CO2 concentration is so much higher in exhaust/flue gas, 10-40% versus 0.04% in the atmosphere, it's much more cost effective in the next 50-ish years.

In another thread today it was pointed out that humans produce 50 gigatonnes of CO2 per year. We have to start somewhere, but grabbing a few tons at a time may not out much of a dent in the problem.
