Facts & Figures

Technology description:

The Climeworks COcapture technology is based on a cyclic capture / regeneration process and a novel filter. During the capture process, atmospheric CO2 is chemically bound to the surface of the filter. Once the filter is saturated, the CO2 is released by heating it to a temperature of about 100°Celsius (212°F), thereby delivering high-purity gaseous CO2. The CO2-free filter can be re-used for numerous capture /regeneration cycles.
