It almost sounds to good to be true: a sought-after raw material produced from a material of which we have too much and, to boot, it does not cost anything. That is precisely what the start-up Carbon Engineering of British Columbia has planned. Together with Global Thermostat from New York and Climeworks from Sweden they want to erect huge walls with ventilators built in. These would suck CO2 out of the air and convert it into fuel via a chemical process, which is described in the video below.
The ability to capture CO2 from the atmosphere is still a fascinating subject but most of methods (almost all of them are still in the testing stage) have a catch: they are very expensive and thus not economically viable. Climate protection costs money. With ideas like this one from Carbon Engineering, that could change.
The Canadian start-up and its partners have their fingers on the pulse with this environmental and business idea because CO2 and other greenhouse and harmful gases could turn out to be a raw material of the future. The Fraunhofer Institute for example, has developed a process that, with the help of bacteria, produces fuels such as kerosene or dyes from industrial waste gases.
