The problem with direct air capture is that it only is good if it exclusively uses renewables, and right now it would be much better to instead use that energy to replace fossil fuels. Only excess renewable energy should be used for it, maybe in places like Scotland that have too much wind power. Capture directly from the source is also better as the concentration of carbon is much higher in the output from a smokestack, and as such has more impact and is more energy efficient too
