Switzerland-based business Climeworks has presented its efficient carbon dioxide (CO2) capture technology at the COP22 Climate Change Conference in Marrakech as companies and countries unite in climate protection.
Climeworks revealed its aim to capture 1% of total global CO2 emissions by 2025 with its CO2 Direct Air Capture (DAC) technology, which is based on a cyclic capture-regeneration process and a novel filter that captures CO2 from ambient air.
During adsorption, atmospheric CO2 is chemically bound to the sorbent’s surface and once saturated, the sorbent is heated to 100°C to drive off and deliver high-purity, gaseous CO2. The DAC technology is currently patent-pending.
