Simple in theory, that is: stop pumping carbon dioxide into the atmosphere. In practice that is rather hard to do. But there is another approach. Having put the stuff into the air, take it out. One proven way of doing this is photosynthesis. Measures to nurture and expand the world's forests come high on the agenda of environmental proposals. But new forests take up a lot of land. How about a high-tech alternative: capturing the CO2 from air by artificial means and tucking it away in the Earth's crust? Air-capture schemes revolve round a process of reversible absorption. First, a stream of air is run over the absorbing material in question, which pulls CO2 out of it. Then the absorber is processed to release the CO2, allowing the device to go back to work and the CO2 to be disposed of. Carbon capture and storage is not a sure thing. Its development has been a lot slower than advocates would have wished. But if air capture can be made economical, then CCS will surely be made even more so, and will be able to sell more carbon dioxide cheaper.
