Audi starts building underground carbon dioxide storage facility

September 8, 2020 0 By autotimesnews

The German automaker is assisted in this by the Climeworks company. With the help of the complex under construction, it will be possible to obtain carbon dioxide from the atmosphere. It will be stored in the bowels of the earth.

A unique underground storage facility will be built on the territory of Iceland. This country was not chosen by chance: it has a suitable geology for this project. The operation algorithm of such a system, which is being promoted by Audi and Climeworks, is as follows: using a special device, air is taken from the atmosphere, which is then passed through a special adsorbent. It also binds carbon dioxide.

A nearby geothermal plant heats the adsorbent to 100 degrees Celsius. This allows the release of carbon dioxide. Then it falls into the water of a geothermal power plant, which delivers it deep underground – 2,000 meters. The work doesn’t end there. CO2 molecules interacting with basalt rock become carbonates. This transformation will have to wait for several years. The water is returned back to the power plant, generating 303 megawatts of electricity and 400 megawatts of heat.

If such a plant is operated daily for the whole day, then it will be possible to remove good volumes of CO2 in a year.
In comparison, in nature, it would take 80,000 trees to remove this amount of carbon dioxide! This project is Audi’s contribution to the environment.

Earlier it became known that Porsche is working on research in the use of synthetic fuels. According to the company’s management, this type of energy can be very efficient until there is a massive switch to electricity.
