Challenges of Direct Air Capture (DAC)
Direct Air Capture (DAC) is technically feasible, but it requires a significant amount of energy and effort to remove CO2 from the atmosphere at a large scale. With millions of molecules in the atmosphere, only a small fraction is CO2. To extract one million tons of CO2, billions of tons of air need to be processed. DAC facilities consist of units resembling shipping containers with fans that pull air through a contactor that reacts with CO2. The resulting CO2 is then compressed, transported, and stored, often underground.
