    Abstract

    A method is provided for a combination of CO.sub.2-capture and storage from the ambient air and fast charging of electric vehicles. A charging station for electric vehicles is also provided.

    Claims

    1. A method for capture and storage of carbon dioxide from the ambient air, the method comprising: taking ambient air through a filter which adsorbs carbon dioxide; and heating the filter in order to release the adsorbed carbon dioxide, wherein waste heat produced during fast charging of at least one electric vehicle at least at one fast charging point is utilized for the heating of the filter.

    2. The method according to claim 1, wherein the filter is heated to a temperature in the range of 60 to 150° C. for the releasing of adsorbed carbon dioxide.

    3. The method according to claim 1, wherein the filter is subjected to reduced pressure for the releasing of adsorbed carbon dioxide.

    4. The method according to claim 1, wherein the carbon dioxide is stored in a collection tank.

    5. The method according to claim 1, wherein taking the ambient air through the filter includes creating an air current by at least one blower fan or at least one fan and taken through the filter, and wherein the electric energy for operating the at least one blower or the at least one fan is provided by a buffer battery of the fast charging point.

    6. A charging station for electric vehicles, comprising: at least one fast charging point for electric vehicles; and at least one module for capture and storage of carbon dioxide from the ambient air, wherein the module can be heated by the waste heat produced during the fast charging of at least one electric vehicle at the at least one fast charging point.

    7. The charging station according to claim 6, wherein the at least one module for capture and storage of carbon dioxide from the ambient air contains a filter, which is adapted to adsorb carbon dioxide from the ambient air and to release it once more upon heating to a temperature in the range of 60 to 150° C.

    8. The charging station according to claim 6, wherein the at least one module for capture and storage of carbon dioxide from the ambient air has a gas inlet and a gas outlet, at least one fan and/or a blower for creating an air flow through the module, and a vacuum device for creating a partial vacuum in the module.

    9. The charging station according to claim 6, wherein the at least one module for capture and storage of carbon dioxide from the ambient air is connected to a collection tank for receiving and storing of CO.sub.2.

    10. The charging station according to claim 6, further comprising a roof on which is arranged the at least one module for capture and storage of carbon dioxide from the ambient air, and beneath which are arranged the at least one fast charging point, at least one buffer battery, at least one unit for control of the at least one fast charging point and the at least one module for capture and storage of carbon dioxide from the ambient air, and at least one collection tank for receiving and storing of CO.sub.2.

    Description

    BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

    [0027] FIG. 1 shows a schematic representation of a module for CO.sub.2-capture from the ambient air.

    DETAILED DESCRIPTION

    [0028] FIG. 1 shows schematically a module 10 for the capture of CO.sub.2 32 from ambient air 30 and the manner of its working. The module 10 has a gas inlet 11, through which ambient air 30 can be sucked in and taken inside the module 10, where a filter 12 is located, which chemically binds CO.sub.2 32. Through a gas outlet 13, air 31 depleted in CO.sub.2 32 is taken out from the module 10. Additional components not shown in the drawing are found in the module 10: a fan or a blower for creating an air flow through the module 10, a device or means of heating the filter 12 and a device or means of generating a partial vacuum in the module 10. A collection tank 20 for receiving of concentrated CO.sub.2 32 is connected by a pipeline 21 to the module 10.

    [0029] The working cycle of the module 10 comprises two phases which are performed in alternation. At the left side of the drawing, the module 10 is shown in the first phase of the working cycle. Ambient air 30 is sucked in through the gas inlet 11 and taken through the module 10, the filter 12 adsorbs CO.sub.2 32 from the ambient air 30 and air 31 depleted in CO.sub.2 32 is taken through the gas outlet 13 from the module 10. At the right side of the drawing, the module 10 is shown in the second phase of the working cycle. The filter 12 is heated and releases adsorbed CO.sub.2 32, which is taken by the pipeline 21 to the collection tank 20 where it is stored.

    [0030] German patent application no. 10 2022 106293.7, filed Mar. 17, 2022, to which this application claims priority, is hereby incorporated herein by reference, in its entirety.

    [0031] Aspects of the various embodiments described above can be combined to provide further embodiments. In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
