I don't see scaling direct air capture of CO2 beyond demo facilities until we are near zero CO2 emissions. But fixed concentrated CO2 streams should have had CO2 capture decades ago.
The problem of course is that no matter how cheap CO2 capture gets, it's not likely to beat dumping it to the atmosphere for free.
