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.

Direct carbon dioxide capture from air

A rechargeable battery includes at least an electrolyte layer, a cathode layer and an anode layer. The electrolyte layer includes a lithium salt compound arranged between a cathode surface of the cathode layer and an anode surface of the anode layer. The anode layer is a nanostructured silicon containing thin film layer including a plurality of columns, wherein the columns are directed in a first direction perpendicular or substantially perpendicular to the anode surface of the silicon thin film layer. The columns are arranged adjacent to each other while separated by grain-like column boundaries running along the first direction. The columns include silicon and have an amorphous structure in which nano-crystalline regions exist.
