Direct air carbon capture and storage (DACCS) is a comparatively new technology for removing carbon dioxide from the atmosphere. Since it would allow large amounts of CO2 to be trapped this technology could also reduce the greenhouse effect. To investigate how effectively this could be implemented with different system configurations of a certain process, researchers in Switzerland analyzed a total of five different configurations for capturing CO2 from the air and their use at eight different locations around the world. Autonomous system layouts prove to be a promising alternative, with a green house gases removal efficiency of 79–91%, at locations with high solar irradiation to avoid the consumption of fossil fuel-based grid electricity and heat. Depending on the combination of technology used and the specific location, CO2 can be removed from the air with an effectiveness of up to 97 percent…read more. Open Access TECHNICAL ARTICLEÂ
