Audi to store carbon dioxide underground
18 Sep 2020|1,148 views
Audi is partnering with Zurich-based environmental start-up Climeworks to build the world's largest direct air capture and storage facility for converting atmospheric CO2 to rock in Iceland.
The facility will filter 4,000 metric tons of carbon dioxide from the air and mineralise it underground. Climeworks is removing 1,000 metric tons thereof from the atmosphere on behalf of Audi.
With direct air capture technology, carbon dioxide is extracted from the ambient air, and air free of CO2 is returned to the atmosphere.
Climeworks' new facility in Iceland transports the CO2 filtered out of the air below the Earth's surface, where natural processes then mineralise it. The carbon dioxide is thus permanently removed from the atmosphere.
The direct air capture technology from Climeworks boasts two major advantages: Lifecycle analyses show that 90% of the CO 2 filtered out of the air is effectively and permanently stored underground. This high reduction capacity makes the facility particularly efficient. The technology can also be scaled up to the megaton-per-year range and thus harbours great potential for the future.
