Where the Future is Built

Large-Scale
Carbon Removal 

Carbon Engineering's technology was developed to capture CO2 directly from the air with an engineered, mechanical system. Similar to how trees absorb CO2 for photosynthesis, Direct Air Capture pulls air into its systems and, through a series of chemical reactions, extracts the CO2.

The difference? DAC technology can capture CO2 much faster with significantly less land use, and delivers the carbon in a pure, compressed CO2 form that can then be stored permanently underground. Of the available methods for atmospheric CO2 removal, DAC is one of the very few viable solutions that can achieve the scale, cost and speed needed to help reach climate stabilization targets by 2050.

Carbon Engineering Technology: How it Works

The system works by pulling air into a large air contactor system, which looks like a cooling tower with a series of giant fans. The air comes in contact with a potassium hydroxide solution where a chemical reaction happens. It is here that the CO2 molecules chemically bind to the potassium hydroxide, trapping them in a liquid solution.

The CO2 trapped in this carbonate solution is then put through a series of chemical processes to increase its concentration while purifying and compressing it—delivering it in gas form ready to be used or stored underground. 

​

This is all done in a system that uses known equipment and processes from other large industries, and reuses the same capture chemicals over and over—make it a scalable and affordable tool for capturing large amounts of CO2 from the air.
