2. How Does Direct Air Capture (DAC) Technology Work?
Direct Air Capture (DAC) technology works by extracting CO2 directly from the ambient air through specialized filters, concentrating it, and then storing it underground to prevent its release back into the atmosphere. This process generally involves three key stages: atmospheric capture, CO2 concentration, and underground storage.
2.1. What Happens During Atmospheric Capture?
In the atmospheric capture stage, DAC facilities use specially designed filters to extract CO2 from the ambient air. These filters are designed to selectively capture CO2 molecules, leaving other atmospheric gases unaffected. The air is drawn through these filters using large fans, and the CO2 molecules adhere to the filter material.
Direct Air Capture Technology
2.2. How Is CO2 Concentrated After Capture?
Once the CO2 is captured, it needs to be concentrated to make it suitable for storage or utilization. This concentration process involves several steps. First, the CO2 is released from the filter material, often through the application of heat or a vacuum. The released CO2 is then purified through a series of filtration and separation processes to remove any impurities and increase the CO2 concentration. According to research from Stanford University’s Department of Chemical Engineering, advanced membrane technologies can efficiently concentrate CO2 with minimal energy consumption.
2.3. Where And How Is CO2 Stored Underground?
The final stage involves storing the concentrated CO2 deep underground. The CO2 is typically injected into geological formations, such as depleted oil and gas reservoirs or deep saline aquifers. In these formations, the CO2 is trapped and prevented from escaping back into the atmosphere. In some cases, the CO2 can react with the surrounding rock to form stable minerals, providing a permanent storage solution. Carbfix in Iceland, for example, uses basalt rock formations to permanently store CO2 through mineralization.
2.4. What Is the Role Of Climeworks in DAC Technology?
Climeworks combines DAC with permanent underground storage (DAC+S) to create a powerful tool for combating climate change. Their process involves atmospheric capture, CO2 concentration, and underground storage. In Iceland, they partner with Carbfix, utilizing a unique geological process to permanently store CO2 underground. The CO2 is injected into deep basalt rock formations, where it reacts with minerals to form stable carbonate minerals. This process effectively locks the CO2 away, ensuring it remains safely stored for over 10,000 years.
2.5. What DAC Projects Are Underway in the U.S.?
In the U.S., Climeworks has announced three projects as part of the U.S. Department of Energy’s Regional DAC Hubs program. They were awarded USD 50 million to kickstart Project Cypress.
