Microporous adsorbents suitable for capturing carbon dioxide directly from the atmosphere.
We've developed new solid adsorbent materials that can capture CO2 directly from air. Our materials are cheap, robust, reusable and efficient at capturing CO2. These adsorbents can play a role in helping industry transition into net zero emissions, or supply CO2to new pathways of use in greenhouses, breweries and building materials.
Carbon dioxide makes up roughly one in 2,500 molecules in our atmosphere. Separating carbon dioxide from other molecules in our air, like water, oxygen and nitrogen, can be a challenge.
Direct air capture (DAC) is a process where CO2 is captured from air using filters or adsorbents (material that can separate different types of molecules) to lower CO2 concentrations.
Our customised, user-friendly, and low-energy-required adsorbents can be reused multiple times. They are easily rechargeable and can be coated or processed to suit different applications.
We've developed some new solid adsorbent technologies with real-world DAC applications. The power of our direct air capture materials lies in their custom-built micropores. These tiny pockets attract and trap carbon dioxide molecules, while allowing other atmospheric molecules to pass by.
Our DAC materials are:
- cheap, robust, and easy to make
- low in toxicity and highly efficient at capturing carbon dioxide
- hydrophobic and work well in humidity.
Our DAC adsorbent technology is simple, effective, and durable with a wide range of applications:
- helping industry transition to net zero emissions
- capturing historical carbon dioxide emissions
- carbonating beverages
- indoor and outdoor atmospheric air purification
- building materials such as cement
- greenhouses for improved crop yields
- food packaging and preservation.
