AirCapture puts atmospheric CO2 to work for customers

This innovative company is capturing carbon dioxide from ambient air and putting the CO2 directly into their customer’s production processes.

While it’s a fact that CO₂ is a harmful greenhouse gas that causes climate change, it is also a valuable industrial commodity that is widely used in a range of applications including food packaging, indoor agriculture and beverage carbonation. In addition, there are many promising technologies that enable the conversion of CO₂ into plastics, chemicals and building materials such as concrete and carbon fiber. An unfortunate reality is that the process of producing and distributing CO₂ can emit significant amounts of the gas into the atmosphere – two or more tonnes emitted for every tonne delivered.

AirCapture is addressing this problem by developing and commercializing DAC (direct air capture) systems that enable businesses to capture atmospheric CO₂ at the point of use, using waste energy available from the customers’ existing processes.

They do this by using bricks with thousands of small channels through them and a chemical coating that absorbs CO₂. When the air travels through the bricks, the tiny holes provide a large surface area where a substantial portion of the CO₂ is absorbed. Low temperature steam is then used to release the CO₂, which is then processed and stored for use.

AirCapture partnered with Synapse to optimize their system design, improve key performance metrics, and enhance manufacturability.

The design target for the prototype was to build a 100-metric ton of CO₂ per year system. To accomplish that, Synapse engineers established the system architecture, performed extensive computational fluid dynamic modeling, simulated airflows, and conducted adsorption/desorption kinetics modeling for process optimization. The resulting design enabled AirCapture to build its first system to demonstrate functionality, optimize processes and operational parameters, and also gain commercial traction with investors and customers.

The impact for AirCapture’s customers and the planet will be significant. Businesses around the world will have a reliable source of carbon neutral or carbon negative CO₂ without the financial and environmental impacts of traditional production and delivery methods.

For Synapse, we’re proud of our partnership with AirCapture and look forward to developing many more innovative solutions in the fight against climate change.
