As far as I understand, current state-of-the-art is between $100-200 per ton CO2 (see https://www.cell.com/joule/fulltext/S2542-4351(18)30225-3). This is from the CO2 capture company Bill Gates has invested in, FWIW.

Yes, multiply that by about three to get the cost per ton of carbon then add the cost of sequestration - your paper only includes the initial capture.
