The concept is based on an industrial apparatus that pushes ambient air through a filter made out of a novel polymer material, where the selectively bonded carbon dioxide in the material is then released using a moisture swing method producing concentrated CO2 gas at high efficiency.

This process of using a moisture swing method is advantageous over other materials and existing Direct Air Capture technologies, as there’s almost no energy required to capture and safely release the CO2.

Using a method of repeating absorption-desorption cycles, this approach enables us to carry out 80 cycles/day in 24 hours capturing and releasing 500g of CO2 with 1kg of filter material a day.

Our technology can be placed anywhere and in order to be operated at the highest efficiency it is best to be placed in a dry and warm climate. When also taking CO2 storage potential into account, Hungary seems promising due to it’s large capacity for geological CO2 storage.
