LNG cost about $2 per MCF to ship. CO2 will be cheaper to ship as you only need to maintain -60C instead of -160C. Though you will need about 100psi of pressure to keep it liquid. Oil costs 2-5$ per barrel. So that would give a range of 14-50$ per m^3. A m^3 of CO2 is 1100kgs.
So somewhere between 14-50 per m^3. At $50 per CCS cost off of concentrated streams and $100 for DAC you’d likely have a market. At the napkin level it’s worth more investigating.

DAC uses about 1200kWh per ton, so at very best you're looking at about $50-90 per ton just for energy if off grid with solar and only doing it when the sun is shining. Add in capital costs and financing, etc and you're probably looking at multiple hundreds per ton and that's after scaling up
