The SMART-DAC process consists of two steps: CO2 absorption from air using membrane gas absorption (MGA) and concentration of the very pure captured CO2 plus at the same time regeneration of the absorbent by membrane electrolysis (ME) / electrodialysis (ED). A smart buffer system between absorption and regeneration steps makes the process flexible and enables the use of low-cost electricity at moments of surplus or by direct use of electricity from solar cells or windmills.
More innovative features
Use of “natural” wind circulation instead of fans or blowers for contacting the air with the absorbent (@zero energy costs).
A fully continuous absorption 24/7 process.
The selected absorbent is chemically stable, non-volatile, not noxious and regenerable without losses.
No use of heat, only electricity; operation independent from heat provider.
Scale-up by numbers, not by size, like all membrane technologies meaning module standardization towards mass production.
A simple unit concept with a small number of (key) equipment items.
An innovative DAC technology with lowest cost potential!
