Engineers at the Massachusetts Institute of Technology (MIT) have developed a new way of removing carbon dioxide (CO2) atmosphere.
The carbon capture device is essentially a large, specialised battery which absorbs CO2 from the air passing over its electrodes as it is being charged up, and then releasees the gas as it is being discharged.
When in use, the device alternates between charging and discharging, with fresh air or feed gas being blown through the system during the charging cycle, and then the pure, concentrated CO2 being blown out during the discharging.
