Removing Carbon From the AIR
Direct Air Capture (DAC) and Carbon Capture and Storage (CCS) interventions are needed to buy time for clean energy technologies to overtake fossil fuels.
HOW IT WORKS
Direct Air Capture methods collect CO2 molecules from ambient air using a sorbent material, such as a calcium oxide-based solid or silicate. The sorbent is then heated to extremely high temperatures, causing captured CO2 to be released in a concentrated stream.
This CO2 can then be sequestered inertly underground or undergo further chemical reactions that allow it to be recycled into fuel, fertilizer, concrete, food products, etc.
