Narrator: Direct Air Capture, also known as DAC, is a process where carbon dioxide is captured from air using filters or adsorbents to lower carbon dioxide concentrations.

Adsorbents are amazing materials that can separate different types of molecules.

DAC can be used to fight global warming.

 

[Animation image changes to show a city, and smoke can be seen emitting from factory chimneys, and a down arrow appears next to a CO2  sign above the city]

 

It can capture historical carbon dioxide emissions, as well as reduce carbon dioxide emissions in different working environments.

 

[Animation image changes to show a “CO2” sign within a circle, and dotted lines join the sign to a bag of cement, three drink containers, and some fruit]

 

The carbon dioxide captured by DAC can be used in many applications from making cement, to carbonating beverages, and helping our farmers produce better yielding crops in greenhouses.

 

[Animation image changes to show high rise buildings on a green hill, and text appears: CO2, 1 in 2,500 molecules]

 

Carbon dioxide makes up roughly one in 2,500 molecules in our atmosphere.

 

[Animation image changes to show a blue screen filled with floating CO2, H2O, and N2 signs]

 

So separating carbon dioxide from other molecules in our air, like water, oxygen and nitrogen, can be a big challenge.

 

[Animation image changes to show a computer and equipment on a lab bench, and adsorbents can be seen on the computer screen with captured CO2 molecules, and text appears above: DAC Development]

 

To solve this problem, we’ve developed some new solid adsorbent technologies with real-world DAC applications.

 

[Camera zooms in on the computer screen on an adsorbent circle, and the image shows the pockets in the adsorbent trapping the CO2 molecules, and letting the O2, N2, and H2O molecules to move past]

 

The power of our technologies lie in their custom-built micropores. These tiny pockets attract and trap carbon dioxide molecules, while allowing other atmospheric molecules to pass by.

 

[Animation image changes to show a DAC Manufacturing line and text appears above: DAC Manufacturing]

 

Our materials are cheap, robust, and easy to make.

 

[Animation image changes to show a down arrow next to a skull and crossbones and an up arrow next to a CO2 sign inside a cage, and text appears: Low Toxicity, High CO2 Capture]

 

They are low in toxicity and highly efficient at capturing carbon dioxide.

 

[Animation image changes to show a close view of the adsorbent and water droplets can be seen moving past the adsorbent]

 

And because they're hydrophobic they work just as well in humidity.

 

[Animation image shows recycling arrows inside the adsorbent]

 

Our customized, user-friendly, and low-energy-required adsorbents can be reused multiple times.

 

[Animation image shows an adsorbent circle appearing on the left with a battery symbol inside, and an adsorbent symbol on the right with a heart symbol with a CO2 sign inside]

 

They are easily rechargeable and are obsessed with carbon dioxide.

 

[Animation image changes to show the adsorbent circle at the centre of the screen joined to symbols of a cement bag, an apple, a fizzy drink bottle, and a CO2 tank]

 

And they can be coated or processed to suit different applications.

 

[Animation image changes to show a city, and a circled factory can be seen on the left, and then the factory disappears, and a fizzy drink bottle appears in its place, and text appears above: Net zero emissions]

 

From helping industry in its transition to net zero emissions, to capturing historical carbon dioxide emissions, adding some extra fizz to your beverage, or to just improving air quality,

our DAC adsorbent technology is simple, effective, and durable with a wide range of applications.
