What is Direct Air Capture (DAC) Technology?

Direct Air Capture (DAC) technology is a process designed to remove carbon dioxide directly from the ambient air. Unlike carbon capture at a source like a power plant, DAC facilities can be located anywhere, actively filtering the atmosphere to reduce the overall concentration of greenhouse gases already present.

The process typically involves large fans that pull air through a filter where a chemical solution or a solid sorbent binds with the CO2 molecules. Once the filter is saturated, it is heated to release the captured CO2 in a concentrated form.

This pure CO2 can then be permanently stored underground or used to create products like carbon-neutral fuels or building materials.

While still an emerging and energy-intensive field, DAC is considered by many scientists to be a necessary tool for achieving long-term climate goals. It is one of the few technologies that can create “negative emissions,” actively reversing the buildup of historical CO2 and helping to restore atmospheric balance.
