Part 4/8:
Direct air capture is a specialized process designed to filter low concentrations of atmospheric CO2. Companies at the forefront of this technology are experimenting with large-scale operations that can handle substantial quantities of CO2. One such company boasts a pilot facility capable of capturing one ton of CO2 per day.
The DAC process generally entails four key steps that enhance the concentration of CO2:
Air Intake: A large fan pulls ambient air into the system.
Chemical Reaction: The air passes through a chemical solution that captures approximately 80% of the CO2 present.
Carbon Pellets: The CO2-rich solution is transformed into solid calcium carbonate pellets.
