The most profitable thing you can do with captured carbon is probably either burning it or turning it into plastic. The problem is that it is orders of magnitude cheaper to pump carbon from the ground instead of capturing it from the air. The second problem is that burning the captured carbon is forbidden if you want to use carbon capture to reverse global warming.
