The present invention concerns a device and process for capturing COfrom air. The device comprises (a) a membrane at least partly permeable for air comprising a solid state COsorbent; (b) at least one sorption chamber; (c) at least one regeneration chamber; (d) means for transporting the membrane from the sorption chamber to the regeneration chamber and back; (e) an inlet for receiving air located on one end of the membrane and an outlet for discharging air depleted in COlocated on the other end of the membrane in the sorption chamber, wherein the device is configured to allow air to flow from the inlet to the outlet through the membrane; (f) means for flowing stripping gas through the membrane into the regeneration chamber; (g) at least one outlet for discharging CO, located in the regeneration chamber; and (h) heating means for heating the regeneration chamber. The device according to the invention provides an efficient and low-cost solution for capturing COdirectly from air.
