We expect this carbon removal technology to remove large volumes of carbon dioxide from the atmosphere year over year—enough to help us curb global temperature rise at 1.5°C, when combined with other global carbon mitigation initiatives.
CARBON ENGINEERING’S DIRECT AIR CAPTURE TECHNOLOGY COMBINES PROVEN SYSTEMS TO CAPTURE CO₂ DIRECTLY FROM THE ATMOSPHERE.
HOW CAN DIRECT AIR CAPTURE HELP?
Direct Air Capture, when deployed at large-enough-scale, may even help us achieve a net-negative world by removing more carbon dioxide from the atmosphere than society emits.
Direct Air Capture is expected to be able to remove atmospheric emissions from hard-to-decarbonize industries such as aerospace, maritime, rail and trucking.
Once captured the CO₂ can be safely and securely stored deep underground in geologic reservoirs.
Captured CO₂ can also be used as a feedstock to produce products such as
low-carbon fuels, cement or plastics.
Carbon Engineering's technology was developed to capture CO₂ directly from the atmosphere 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? Direct Air Capture technology is expected to capture CO₂ much faster with significantly less land use, and delivers the carbon in a pure, compressed CO₂ form that can then be stored securely underground.
Of the available methods for atmospheric CO₂ removal, Direct Air Capture is one of the solutions that we believe can achieve the scale and speed needed to help reach emissions reduction 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 will all be done in a system that uses proven technology, equipment and processes from other large industries, and reuses the same capture chemicals over and over—making it a scalable and affordable tool for capturing large amounts of CO₂ from the air.
OUR FIRST LARGE-SCALE PLANT IS UNDERWAY
At 1PointFive, we are committed to reaching carbon emission reduction targets through rapid deployment of Direct Air Capture technology. That’s why 1PointFive teamed up with Worley for FEED of the largest Direct Air Capture facility in the world. With an anticipated capture capacity of one million tonnes of CO₂ each year when fully operational, DAC 1 is expected to come online in 2024.
