What is Direct Air Capture?

Direct air capture, or also known as D.A.C., is a technology that involves removing carbon dioxide (CO2) from the atmosphere using various methods, such as chemical reactions, absorption, or adsorption (the process by which a solid holds molecules of a gas or liquid or solute as a thin film). The captured CO2 can be used for various purposes, such as producing synthetic fuels, or the carbon could be stored underground.

D.A.C. systems typically use large fans to draw in air, which is then passed through filters or absorbent materials that selectively capture CO2. The captured CO2 is then separated from the filter or absorbent material and stored, either permanently or temporarily.

The goal of D.A.C. is to reduce the amount of CO2 in the atmosphere, which is a major contributor to climate change. By capturing and storing carbon, D.A.C. can help to offset emissions from sources that are difficult to decarbonize, such as industrial processes or transportation.

However, D.A.C. is currently expensive compared to other carbon reduction methods and requires significant energy input to operate, making it less efficient than other forms of carbon capture. Nonetheless, it is seen as a potentially valuable tool in the fight against climate change, especially as the technology continues to improve and costs decrease.
