Carbon Dioxide Removal
Direct Air Capture
Direct air capture is the technique of scrubbing carbon dioxide directly from the sky through large mechanical facilities. The technique can be used to obtain carbon for making a byproduct or fuel. Direct air capture and storage (DACS) means storing that carbon dioxide in a long-term reservoir. The two main approaches involve either (1) liquids or surfaces that chemically interact with carbon dioxide, or (2) membranes that physically trap the carbon dioxide on solid surfaces.
