What is it?
Direct Air Carbon Capture and Storage (DACCS) involves capturing carbon dioxide (CO2) directly from the atmosphere and storing it securely, typically underground. This process is designed to reduce the amount of CO2 in the atmosphere. DACCS is considered a form of negative emissions technology, as it actively removes CO2 from the air. The main technologies used in DACCS include Absorption-based systems (chemical sorbents, moisture swings), Adsorption-based systems (Solid sorbents, temperature swings, pressure swings), Membrane-based systems, Electrochemical systems (fuel cells), Cryogenic separation, Geological storage, and Mineral carbonation.
Why is it important?
DACCS can help reduce atmospheric CO2 levels and help to achieve net zero targets. DACCS can play a significant role in offsetting emissions from hard-to-abate sectors, such as aviation and agriculture. Unlike some other carbon capture methods, DACCS can remove CO2 that has already been emitted, making it a valuable tool for addressing the cumulative effects of past emissions.
What industries will it impact?
Energy (integrated with power plants), Oil & Gas, Manufacturing, Transportation, Agriculture, Carbon markets and trading, Waste management.
