Direct Air Capture

  Direct Air Capture (DAC) is a technology that removes carbon dioxide (CO₂) from the atmosphere.

​

  Using high-powered fans, air is drawn into a processing facility where the CO₂ is separated through a series of chemical reactions. Then the CO₂ is either permanently stored in underground reservoirs through secure geologic sequestration, or is used to make new products such as building materials and low-carbon fuels.

  1PointFive is developing Carbon Engineering’s Direct Air Capture technology. This technology works by drawing air into a facility using a series of large fans. The air comes in contact with a chemical solution that binds to the CO₂ molecules. The CO₂-rich solution is then processed through a series of reactions that separate, purify and compress the CO₂. The resulting CO₂ can then be permanently stored or used as a feedstock for other products.

  Today there are a total of 18 DAC facilities in operation from a number of different companies around the world. All told, they capture just 0.01 million tonnes of CO₂ per year.¹

​

  In 2022, 1PointFive began construction on what will be the largest DAC facility in the world. Once fully operational, our first facility is expected to capture 500,000 tonnes of CO₂ per year and is planned to be commercially operational in mid-2025.
