Cross - Reference to Related Applications

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 433,949, filed on December 20, 2022, and U.S. Provisional Application No. 63 / 611,314, filed on December 18, 2023. The disclosures of the above - mentioned applications are incorporated herein by reference for all purposes. Technical Field

[0002] The present disclosure relates to adsorbent - material composite articles and structures for supporting adsorbent - material composite articles during adsorption and desorption processes for the direct air capture (DAC) of carbon dioxide (CO2). Background Art

[0003] Increases in carbon dioxide (CO2) levels associated with greenhouse gas emissions have been shown to be harmful to the environment. As reported by the Climate.gov article "Climate Change: Atmospheric Carbon Dioxide", the average level of CO2 in the atmosphere in 2019 was 409.8 ppm, the highest level in the past 800,000 years. It was also reported that the rate of increase of CO2 in the atmosphere is far higher than the rates of previous decades.

[0004] To limit climate change to an acceptable level, it is necessary not only to reduce CO2 emissions to zero in the near future but also to achieve CO2 negative emissions. To achieve negative emissions, there are several possibilities, such as burning bio - materials for power generation, which is combined with capturing CO2 from combustion flue gas and then sequestering CO2 (BECCS), or with the direct air capture (DAC) of CO2.

[0005] Direct air capture of CO2, known as "DAC", is one of several means of reducing anthropogenic greenhouse gas emissions and has an extremely attractive economic prospect as a non - fossil, location - independent CO2 source for commodity markets and synthetic fuel production. Specific advantages of capturing CO2 from the atmosphere include: a) DAC can address the problem of decentralized emission sources (e.g., vehicles... on land, sea, and air), which account for a large portion of global greenhouse gas emissions and currently cannot be captured at the emission location in an economically viable way; b) DAC can address legacy emissions and thus can achieve true negative emissions; c) DAC systems do not need to be attached to an emission source but can be location - independent and can be located at a location for further processing or use of CO2.

[0006] There is an increasing motivation to develop and improve the adsorption and desorption cycle structures for adsorbent materials so that these processes can be performed more efficiently. Summary of the Invention

[0063] The present disclosure is not intended to be read in a limiting manner. For example, terms used in this application should be read broadly in the context of the meaning that would be attributed to such terms by a person of ordinary skill in the art.

[0064] Regarding imprecise terms, the terms "about" and "substantially" are used interchangeably to refer to a measurement that includes the stated measurement value and also includes any measurement value that is reasonably (substantially) close to the stated measurement value. As understood and readily determinable by a person of ordinary skill in the relevant art, a measurement value that is reasonably (substantially) close to the stated measurement value deviates from the stated measurement value by a reasonably small amount. Such a deviation may be attributable to, for example, measurement error, differences in measurement and / or manufacturing device calibration, human error in reading and / or setting the measurement value, fine-tuning for optimizing performance and / or structural parameters in view of differences in measurement values related to other components, particular implementation scenarios, imprecise adjustment and / or manipulation of an object by a person or a machine, and / or the like. In cases where a person of ordinary skill in the relevant art would not readily determine a value for such a reasonably small difference, the terms "about" and "substantially" may be understood to be the stated value plus or minus 10%.

[0065] In addition, the term "direct air capture (DAC) device" is defined to include examples having a single DAC cartridge and multiple DAC cartridges (e.g., in a stacked configuration as further described herein). The term "DAC cartridge" is defined to include a single frameless or framed structure (having any suitable frame for defining the shape and dimensions of the structure as further described herein) that is at least partially filled with an adsorbent material composite article(s), and can be used to directly capture CO2 from the atmosphere. As defined herein, a DAC device is also referred to as a carbon capture device that performs any method of separating gaseous CO2 from a gas mixture in the form of ambient air. Exemplary adsorbent articles and cartridges supporting the adsorbent articles are further disclosed in International Publication Nos. WO 2022 / 187730 (W.L. Gore & Associates, Inc.) and WO 2022 / 187733 (W.L. Gore & Associates), the entire contents of which are incorporated herein by reference for all purposes. Description of various embodiments

[0066] The present disclosure relates to devices for direct air capture (DAC) for adsorbing and separating one or more desired substances from a source stream, such as extracting carbon dioxide (CO2) from a dilute feed stream such as air. Such DAC devices can also be used in other adsorption methods and applications. These methods include, but are not limited to, adsorbing substances from various inputs, including other gas feed streams (e.g., combustion exhaust) and liquid feed streams (e.g., seawater). The substances adsorbed are not limited to CO2. Other substances adsorbed can include, but are not limited to, other gas molecules (e.g., N2, CH4, and CO), liquid molecules, and solutes. In certain embodiments, the input may be dilute and contain the adsorbed substance at an order of magnitude of parts per million (ppm).

[0067] Examples of articles and techniques for DAC include using articles that include a substrate, such as a monomer that can support or be coated with an adsorbent material. By varying the type of substrate and the adsorbent used, various variations can be established. However, these previously established articles and methods have limitations in terms of their ability to efficiently cycle between adsorption and desorption states. They also have limitations with respect to the energy required to perform the process.

[0068] Many times, swing adsorption is a very energy-consuming process. Whether it is pressure swing, temperature swing, or humidity swing, energy is required during many operating phases.

[0069] As an example, in temperature-vacuum swing adsorption (TVSA, temperature and vacuum swing adsorption) for direct air capture (DAC) of CO2, the adsorption step may require a fan to force a large volume of air through an air contactor, such as a ceramic monolith or a plate pack, the plate pack having a series of adjacent plates with spacing therebetween. When the operator deems it useful to start desorption (usually when the contactor has adsorbed a certain amount of CO2), the fan can be turned off or deactivated to terminate the adsorption phase.

[0070] Once the adsorption phase is terminated, the inlet and outlet of the module are closed, which provides a seal for negative pressure. Next, a vacuum can be applied to evacuate the air within the module, and steam can be applied to raise the temperature to a point where the adsorbent releases CO2. Then, this CO2 is pumped out of the module space and further processed to remove humidity. In the above process, the desorption step requires a large amount of energy to heat and then cool the module. During desorption, the temperature throughout the module volume must be raised from the ambient temperature (which can be very low depending on the geographical location) to a temperature conducive to removing CO2 from the adsorbent. In many cases, steam is used to raise the temperature since steam is efficient in transferring heat to a substance. The object of the present invention is to improve the efficiency of the DAC system by providing a module capable of having a variable volume. For example, during the adsorption step, the air contactor or module can have a volume that allows air to flow through at a very low pressure, thereby facilitating the adsorption of CO2, and during the desorption step, the air contactor or module can have at least a second reduced volume, which saves energy by reducing the amount of volume that needs to be heated. Reducing the volume will also reduce the energy required to apply negative pressure, although in some cases the negative pressure may be the force causing the volume reduction.

[0071] Similarly, in the processes of humidity swing adsorption and pressure swing adsorption, the desorption step is usually the most energy-consuming. In humidity swing, energy is used to move moisture to the contactor, and energy is used to dry the contactor once CO2 is desorbed from it. In pressure swing, energy is used to apply pressure to the adsorbent to cause CO2 to be released from the adsorbent. In both cases, it may also be beneficial to provide an air contactor or module capable of having a variable volume configuration. Current air contactors and modules are lacking in this regard.

[0072] Figure 1A A shelf unit 101 for a DAC device 100 is shown. The shelf unit 101 includes a frame, a support frame or a frame structure 102 for holding or supporting therein a plurality of adsorbent articles 106 as shown in Figure 1B and Figure 1C or cartridges holding a plurality of adsorbent articles. As shown in Figure 1CAs shown, the article 106 can be held in place within the DAC device 100 (also referred to herein as the DAC assembly) using the frame structure 102, which includes a plurality of holes or perforations (not shown) through which fluids such as a desorption medium (in some examples, the desorption medium can be one or more of the following: hot liquid, steam, saturated steam, superheated liquid, or any heat transfer substance, etc.) are allowed to flow during the adsorption / desorption process. The desorption medium referred to herein can include one or more of the following: hot liquid, steam, saturated steam, superheated liquid, or any heat transfer substance, etc., as further disclosed in U.S. Patent Application No. 18 / 234,014 (Gore & Associates), the disclosure of which is incorporated herein by reference for all purposes. The article 106 can be inserted or disposed in and supported by the housing portion 104 (also referred to as a chamber or internal volume) of the shelf unit 101 to form the DAC device 100, which can be installed in a DAC reactor in any suitable configuration as further explained herein. The DAC reactor referred to herein can include what is further disclosed in International Publication Nos. WO 2021 / 239747 (Climeworks AG) and WO2023 / 104656 (Climeworks AG), the disclosures of which are incorporated herein by reference for all purposes.

[0073] The shelf unit 101 has two types of dividers: a first divider 108 and a second divider 110 that separate different housing portions 104 from each other. In some examples, the first divider 108 can be substantially vertical, while the second divider 110 can be substantially horizontal. As further disclosed herein, the dividers can have additional different orientations. The dividers 108 and 110 can divide the internal volume of the shelf unit 101 into multiple rows and columns of individual housing portions 104 such that the article 106 or the cartridge of the article 106 can be inserted into their corresponding housing portions. The dividers 108, 110, and the frame structure 102 can include holes or perforations ( Figures 1A to 1C not explicitly shown but schematically represented by the arrows flowing through the frame structure 102 and the dividers 108, 110) such that fluid flow (such as air flow or desorption medium flow) can flow into and out of adjacent housing portions 104 and flow between them.

[0074] The shelf unit 101 can also have a distribution plate 112 or manifold that operates to evenly distribute an incoming liquid, such as an air and / or desorption medium stream 103a or stream (schematically represented by the large arrow) into smaller and more fluid medium streams 103b, 103c, and 103d or streams (schematically represented by the smaller and more arrows; see Figure 1B) and enter each housing portion 104 to facilitate more efficient adsorption and desorption processes. If necessary for the adsorption and desorption processes, the fluid medium flow can also pass between the housing portions 104 in the manner of flow 103d, and / or can leave the shelf unit 101 in the manner of flow 103e. The distribution plate 112 can provide channels or openings to make the smaller fluid flows consistent in measurable parameters such as flow rate, pressure drop, density change, temperature change, or observable flow path. Alternatively, the distribution plate 112 can provide channels or openings to direct a greater flow rate to specific areas connected to the distribution plate 112, such as by providing a greater flow rate to the openings near the outer peripheral edge of the distribution plate 112, a lesser flow rate to the center of the distribution plate 112, and / or a greater flow rate to the corners of the distribution plate 112.

[0075] As shown in the figure, the frame structure 102 of the shelf unit 101 can be a single integral structure that includes a plurality of compartments or housing portions (spaces) 104 for discretizing the adsorbent articles 106. The adsorbent articles 106 or the cartridges of the adsorbent articles can be stored or contained within each compartment / housing portion 104 such that different types of adsorbent articles can be stored or contained within different compartments / housing portions, while reducing the need for self-support or support by cartridges for individual adsorbent articles.

[0076] The shelf unit 101 can facilitate the entry, exit, and circulation of air between different compartments / housing portions 104, thereby allowing air to flow from one location to another. During the adsorption and desorption processes, this air flow helps to dry the adsorbent articles after being treated with a desorption medium (e.g., steam). As further disclosed herein, the shelf unit 101 can include means for collecting the condensate (e.g., water formed due to steam condensation) formed during the adsorption and desorption processes. In some examples, the collected condensate can be reused in subsequent adsorption and desorption processes, thereby providing an efficient cycle of the desorption medium. In some examples, the collected condensate can be redirected to a discharge outlet. The shelf unit 101 can include local or integrated heating / cooling features, such as a circuit for providing cold water and heating elements to form steam from the liquid water collected in the shelf unit 101, as further disclosed herein.

[0077] In Figure 1BIn [description], when the media stream 103b contacts the adsorbent article 106 (also referred to as an air contactor), the flow of the media stream 103c (schematically represented by multiple long wavy arrows) flowing through the adsorbent article 106 weakens. As shown by the arrow 103c, as they progress downstream, the quantity increases and becomes thinner. The frame structure 102 has an upstream position 102a and a downstream position 102b, defining a path for conveying the desorbing medium through the frame 102, as shown by the arrow 103c, which points from the upstream position to the downstream position. The desorbing medium enters the frame 102 through the distribution plate 112 and then enters the frame 102 at the upstream position 102a. The air contactor or adsorbent article 106 is positioned inside the housing portion (or space) 104 of the frame 102. In the example shown, the shelf unit 101 provides a support for each adsorbent article 106 to hold the position of each adsorbent article 106 at a desired position within the housing portion 104. Alternatively, the housing portion 104 can be subdivided to provide a plurality of adjacent and separate housing compartments within the space 104, each housing compartment separately supporting the adsorbent article 106. In some examples, there can be multiple inlets through which the desorbing medium can be introduced into the frame 102 (e.g., as shown in Figure 2 , Figure 3A and Figure 3B ). In some examples, different adsorbent articles 106 can be included in different housing portions (or spaces) 104 within the same frame 102.

[0078] In Figure 1C , six (6) groups of multi-adsorbent articles 106 are shown, labeled "106A" to "106F" respectively. In some examples, each group may differ in one or more of the following aspects: the spacing between adjacent articles (air contactors) 106 within the group, the type of adsorbent material used within the group, the amount of adsorbent material used, etc. The dividers 108 and 110 ( Figure 1A ) can facilitate the flow of air or desorbing medium from group 106A to group 106D, from group 106B to group 106E, and / or from group 106C to group 106F, as shown by the flow or stream 103d, or flow through the flow or stream 103e to the outside of the unit 101. In some examples, a portion of the desorbing medium stream can flow from one side to the other side instead of simply flowing downstream, e.g., from 106A to 106B, from 106D to 106E, etc. It can be understood that the dividers 108 and 110 can be advantageously arranged to direct the medium stream to flow from one side to the other side and / or downstream.

[0079] In some examples, during each adsorption and desorption cycle, the media stream 103 flowing through the DAC device 100 can be any suitable feed stream. For example, the feed stream can be air flowing through the DAC device 100, and one or more components can include CO2 or any of the other aforementioned gas molecules. In some examples, desorbing the article 106 can include immersing the article 106 in a desorption source, such as water (or alternatively, in some examples, using steam or heat as the desorption source), to facilitate the desorption of CO2. The feed stream can then escape from the DAC device 100 in the form of a gas or vapor.

[0080] As Figure 1D shown, the cross-flow of the DAC device 100 is defined by two stages. In the first adsorption stage (Stage 1), air flows into a cartridge containing an adsorbent article (adsorbent assembly) in a first direction as shown by the horizontal arrow, and the cartridge is shown as a cube in the figure. During Stage 1, carbon dioxide in the incoming air is captured inside the adsorbent assembly. In the second desorption stage (Stage 2) after Stage 1, the desorption medium flows into the cartridge in a second direction as shown by the vertical arrow. The vertical and horizontal directions can be interchanged. The cartridge or the adsorbent assembly can cycle between Stage 1 and Stage 2, such that Stage 1, which occurs after Stage 2, can facilitate the drying of the adsorbent assembly, which may have become wet or moist during Stage 2 due to the use of a desorption medium such as steam. Advantageously, the cross-flow helps to efficiently dry the adsorbent article, thereby improving the efficiency of the adsorption / desorption cycle.

[0081] In Figure 2 A, a side view of the shelf unit 101 shows that the desorption medium stream 203 enters the unit 101 in the form of a stream (or inflow) 203a, which starts from an upstream location or upstream side 202a of the unit 101 and passes through ( Figure 2A channel extending (leftward in the figure) through the unit 101 reaches the downstream position or downstream side 202b of the unit 101. In some examples, the shelf unit 101 may include internal channels 200 that define a path for the desorption medium 203 to flow through the unit. For example, a second separator 110 may be provided, which extends from the upstream side 202a to the downstream side 202b of the unit, and each separator may include an internal channel 200 defined by the separator 110, which is fluidly coupled to at least one manifold 202 having at least one inlet 204 to receive the incoming desorption medium 203a. The separator may also be referred to as a support member for the shelf unit 101 because the separator can be formed to support the unit 101 while providing internal channels 200 that direct the medium flow and divide the flow into streams 203b. In the drawings, the white arrows 203b show the downstream progression and the distribution of the incoming medium flow 203a when the divided streams 203b enter the space 104, and then, during the desorption process, when the flow is distributed within the adsorbent article disposed within the space 104, further divides into smaller or divided streams. As Figure 1B and Figure 1C shown, the smaller or divided streams (e.g., 103d) flow from one space 104 to another space 104.

[0082] The frame structure 102 of the shelf unit 101 is for supporting at least one adsorbent article 106 therein, which has an upstream position 202a and a downstream position 202b that facilitate the flow of the desorption medium. The shelf unit 101 includes at least one manifold 202 that defines at least one inlet 204 configured to receive the desorption medium 203a at the upstream position 202a of the shelf unit 101. The shelf unit 101 further includes a set of support members or support structures (also referred to as separators 108 and 110), which form a plurality of housing portions (or spaces) 104 in which the adsorbent articles are received. The first support members or separators 108 extend parallel to each other in a first orientation, while the second support members or separators 110 extend parallel to each other in a second orientation different from the first orientation. These orientations can be vertical and horizontal, and depending on the orientation of the shelf unit 101, these designations can be interchanged; for example, in Figure 1A one case, the first support members or separators 108 are "vertical" members, but in Figure 2 another case, the first support members or separators 108 are "horizontal" members.

[0083] Further referring to Figure 2, the second support member or spacer 110 includes an internal channel 200 that extends from and is in fluid communication with an inlet 204 for receiving a desorbing medium into the channel 200 to facilitate adsorption. The channel 200 has perforations 206 (also referred to as holes, openings, or slits) through which the desorbing medium can flow into the housing portion (or space) 104, as indicated by the white arrows.

[0084] In some examples, a single channel 200 can have a first set of perforations 206A facing one passageway and a second set of perforations 206B facing the other (opposite) passageway, and the two sets of perforations can direct the desorbing medium into different housing portions (or spaces) 104 within the shelf unit 101. In some examples, a single support member or spacer 110 can include a first surface (e.g., a top surface) 208A and a second surface (e.g., a bottom surface) 208B, the first surface defining a first set of openings or perforations 206A, the second surface being opposite the first surface and defining a second set of openings and perforations 206B such that the first set of openings or perforations 206A is positioned offset from the second set of openings or perforations 206B. In some examples, the openings or perforations 206 have various opening sizes that are configured to evenly distribute the desorbing medium across different sections of the housing portion. For example, the openings or perforations 206 located closer to the upstream position 202a of the frame 102 can have a smaller opening size compared to the openings or perforations 206 located closer to the downstream position 202b of the frame 102.

[0085] In Figure 3A the example shown, the openings 206 are part of extensions (also referred to as "recesses") 300 formed in the second support member or spacer 110. The second spacer 110 includes extensions 300 that are formed around the first set of openings or perforations 206A on the first surface 208A and around the second set of openings or perforations 206B on the second surface 208B, and the extensions 300 extend inward from the surfaces 208A and 208B into the internal channel 200. In some examples, the extensions 300 have a funnel-shaped portion 302 that extends inward from the surrounding surface 208 towards the perforations 206 into the internal channel 200.

[0086] In some examples, only the uppermost second support member 110A can include perforations 206B only along the bottom surface 208B of the support member 110A, and only the lowermost horizontal support member 110B can include perforations 206A only along the top surface 208A of the support member 110B. When the desorbing medium 203a enters, the desorbing medium 203b flows through the hollow horizontal support member 110 and exits through the perforations 206 (as Figure 1B(flow of the medium stream 103c as shown). In some examples, the sizes of these perforations 206 may vary based on engineering principles to provide a uniform steam supply and coverage.

[0087] Advantageously, as Figure 3A and Figure 3B shown, the extension 300 formed on the first surface 208A can be configured to form a funnel-shaped or other gravity-fed or core-shaped configuration such that the liquid water condensed inside the housing portion 104 can flow through the extension into the internal channel 200, while the extension 300 formed on the second surface 208B is configured to form a reservoir 304, as Figure 3B shown, the condensed liquid water will accumulate in the reservoir 304 inside the internal channel 200.

[0088] Referring to Figure 2 、 Figure 3A and Figure 3B in combination, in some examples, the DAC device 100 may include an upstream location 202a and an opposite downstream location, where the influent 203a is received by the DAC device 100 at the upstream location 202a, and the DAC device 100 further includes a plurality of filter cartridges disposed adjacent to each other, where each filter cartridge supports a plurality of adsorbent articles 106. In some examples, the filter cartridges define spaces or housing portions 104 in which the adsorbent articles 106 may be disposed. For example, in Figure 1B and Figure 4 the adsorbent articles 106 may be supported by one or more filter cartridges, while in Figure 1C the groups of adsorbent articles 106A to 106F may be supported by a plurality of filter cartridges, such as each group 106A to 106F being supported by one or more filter cartridges. In some examples, the plurality of filter cartridges may include a bottom filter cartridge and a top filter cartridge disposed above the bottom filter cartridge. Both the top filter cartridge and the bottom filter cartridge extend between the upstream location 202a and the downstream location 202b. In some examples, the internal channel 200 may include a top channel 200A, a bottom channel 200C, and an intermediate channel 200B. The top channel 200A may be disposed above the top filter cartridge and extend along the length of the top filter cartridge to collect the water provided by the top portion of the influent, which is labeled "203b (top)" in Figure 2 The bottom channel 200C may be disposed below the bottom filter cartridge and extend along the length of the bottom filter cartridge to collect the water provided by the bottom portion of the influent, which is labeled "203b (bottom)" in Figure 2 The intermediate channel 200B may be disposed between the top and bottom filter cartridges and extend along at least one of the length of the top filter cartridge and the length of the bottom filter cartridge to collect the water provided by the intermediate portion of the influent, which is labeled in Figure 2is marked as "203b (middle)". The DAC device 100 may also include a common outlet, such as, for example, Figure 4 a drain or outlet 400 as shown, which is arranged to receive water from at least one of the top channel 200A, the middle channel 200B, and the bottom channel 200C.

[0089] Referring to Figure 3A , Figure 3B and Figure 4 , in some examples, the top channel 200A may include a top channel upper surface 308A that is disposed on a top channel lower surface 310A within the top channel 200A. The top channel lower surface 310A may include a reservoir 304A and perforations 206 disposed between the reservoirs 304A. The top channel upper surface 308A may include a top channel drip point 306A that is shaped to collect water on the top channel reservoir 304A. The top channel reservoir 304A may be in communication to deliver water to a top channel outlet 402A that is in communication with the common outlet 400, as Figure 4 shown. In some examples, the bottom channel 200C may include a bottom channel upper surface 308C that is disposed on a bottom channel lower surface 310C within the bottom channel 200C. The bottom channel lower surface 310C may include a bottom channel reservoir 304C. The bottom channel upper surface 308C may include perforations 206 that define a bottom channel drip point 306C that is shaped to collect water on the bottom channel reservoir 304C. The bottom channel reservoir 304C may be in communication to deliver water to a bottom channel outlet 402C that is in communication with the common outlet 400. In some examples, the middle channel 200B includes a middle channel upper surface 308B that is disposed on a middle channel lower surface 310B within the middle channel 200B. The middle channel lower surface 310B may include a reservoir 304B and perforations 206 disposed between the reservoirs 304B. The middle channel upper surface 308B may include perforations 206 that define a middle channel drip point 306B that is shaped to collect water on the middle channel reservoir 304B. The middle channel reservoir 304B may be in communication to deliver water to a middle channel outlet 402B that is connected to the common outlet 400.

[0090] In some examples, the manifold 204 may be disposed between the inflow 203a and at least one of the top channel 200A, the bottom channel 200C, and the middle channel 200B. Referring to FIG. 5, in some examples, the top channel 200A includes a top channel cooling channel 500 that is configured to promote water collection by cooling the vapor located inside the top channel 200A. In some examples, the top channel 200A may include a top channel heating element 504 that is configured to generate vapor by heating the water collected inside the top channel 200A by heating the water located inside the top channel 200A. In some examples, the bottom channel 200C includes a bottom channel cooling channel 500 that is configured to promote water collection by cooling the vapor located inside the bottom channel 200C. In some examples, the bottom channel 200C includes a bottom channel heating element 504 that is configured to generate vapor by heating the water collected inside the bottom channel 200C by heating the water located inside the bottom channel 200C. In some examples, the middle channel 200B includes a middle channel cooling channel 500 that is configured to promote water collection by cooling the vapor located inside the middle channel 200B. In some examples, the middle channel 200B includes a middle channel heating element 504 that is configured to generate vapor by heating the water collected inside the middle channel 200B by heating the water located inside the middle channel 200B. Referring to Figure 6C , the DAC device 100 may include a perforation control mechanism 600 that is operatively coupled to the perforation 206 and is configured to control the opening and closing of the perforation 206.

[0091] Reference Figure 3A and Figure 3B , in some examples, the uppermost second support member 110A may include a plurality of recessed surfaces 306 without openings, as Figure 3B shown, these recessed surfaces 306 cause the condensate formed on the surface to gather in the form of water droplets at the tip portions of the recessed surfaces 306, and these condensates will be collected in the reservoir 304 located below. When the desorbing medium cools and condenses, in some examples the desorbing medium may be vapor, and liquid water forms on the surfaces of the adsorbent article 106 and the shelf unit 101.

[0092] When liquid water collects within the reservoir 304 or another water receiving surface to a critical size and forms a water droplet, surface tension and gravity will act on the water droplet to cause it to fall downward. The shelf unit 101 is designed to collect liquid water from the adsorbent article 106 above, such as guiding water into the frame structure 102 via recessed perforations, which can prevent or reduce the upper adsorbent articles (such as 106A, 106B, 106C) located in the upper housing portion from causing the lower adsorbent articles (such as 106D, 106E, 106F) located in the lower housing portion to receive water from the upper articles and become wet with water from the condensate that is received from adjacent articles.

[0093] The position of the recessed surface 306 and the reservoir 304 can be configured such that the recessed surface 306 and the perforations 206 are not aligned with the vertical axis. For example, they are offset from each other to prevent liquid from flowing from the upper article to the lower article. Additionally, in some examples, the lowermost second support member 110B can have a substantially flat portion that forms a shallow or low-profile reservoir 304C, as Figure 3B shown. The above-described configuration also has other advantages, including but not limited to, for example, reducing the dissipation of the desorbing medium when the desorbing medium flows through the adsorbent article, and also controlling condensation within the structural frame of the shelf unit, for example, by preventing or reducing the risk of condensate formed in the upper housing portion from transferring to the lower housing portion located below it.

[0094] In Figure 4 the shelf unit 101 is inclined at an angle (θ) relative to its bottom surface, relative to a true horizontal surface, and / or relative to the Earth's surface. The angle θ can be any suitable angle, such as 1 degree to 3 degrees, 3 degrees to 5 degrees, 5 degrees to 8 degrees, 8 degrees to 10 degrees, 10 degrees to 13 degrees, 13 degrees to 15 degrees, 15 degrees to 18 degrees, 18 degrees to 20 degrees, 20 degrees to 25 degrees, 25 degrees to 30 degrees, 30 degrees to 35 degrees, 35 degrees to 40 degrees, 40 degrees to 45 degrees, 45 degrees to 50 degrees, 50 degrees to 55 degrees, 55 degrees to 60 degrees, 1 degree to 60 degrees, or any other suitable range or value therebetween. This inclination enables the liquid (such as condensate) inside the channel 200 to be discharged in a predetermined direction, as shown by the dashed arrow, such that the redirected water flows towards the drain or outlet 400. The drain or outlet 400 can be fluidly coupled to the manifold 202 and is located at a different position from the inlet 204. The adsorbent article 106 can be pre-configured in the form of a parallelogram as shown, so that the flat sheet adsorbent polymer composite (SPC) remains vertical and allows all components of the SPC to be substantially the same, while conforming the shape of the adsorbent article 106 to the shape or size of the cartridge support unit, such as the housing portion 104 of the shelf unit 101.

[0095] In some examples, the inclination can be defined by the angle (φ) between the first orientation of the first support member or separator 108 and the second orientation of the second support member or separator 110, or by the corresponding angle provided in the article 106 or the cartridge supporting the article 106. When the first support member 108 is vertical and the second support member 110 is horizontal (or when the article / cartridge provides corresponding vertical and horizontal surfaces), the angle φ between them is 90 degrees. In an inclined configuration, the angle φ between them can be 30 degrees to 35 degrees, 35 degrees to 40 degrees, 40 degrees to 45 degrees, 45 degrees to 50 degrees, 50 degrees to 55 degrees, 55 degrees to 60 degrees, 60 degrees to 65 degrees, 65 degrees to 70 degrees, 70 degrees to 75 degrees, 75 degrees to 78 degrees, 78 degrees to 80 degrees, 80 degrees to 83 degrees, 83 degrees to 85 degrees, 85 degrees to 87 degrees, 87 degrees to 89 degrees, 30 degrees to 89 degrees, or any other suitable range or value therebetween. Accordingly, by utilizing gravity to increase the conveyance of water towards the outlet 400, the inclination causes condensate to be directed towards the outlet 400 such that the condensate collected from the adsorbent article 106 in the housing portion 104 flows in a predetermined direction.

[0096] In Figure 5A and Figure 5B , the second support member or separator 110 can include an internal channel 200 and at least one cooling channel 500 that extends from and is in fluid communication with an inlet for the internal channel to collect water, and the cooling channel is located within the internal channel 200 and is configured to facilitate the collection of liquid (e.g., water) by cooling a desorbing medium (e.g., steam) located within the internal channel 200. The separator 110 can also include (or, conversely, can have) at least one heating element 504 that is located within the internal channel 200 and is configured to generate steam by heating the water collected within the internal channel 200 using the water collected within the internal channel 200. Additionally, the separator 110 can include a plurality of openings (perforations) 206 through which: (1) the steam generated within the internal channel 200 is configured to flow into the housing portion 104 in which the adsorbent article 106 is received to facilitate adsorption; and (2) the condensate formed within the housing portion 104 is configured to flow into the internal channel 200.

[0097] In some examples, a submerged heating element 504 is utilized to generate steam within the shelf unit 101. Since at sea-level atmospheric pressure, the temperature of the steam can reach or exceed 100 degrees Celsius, a cold water circuit (which can be part of or included in the cooling channel 500) can be provided directly above the water level to control the temperature by varying the temperature and flow rate of the circuit (e.g., within the cooling channel 500). Condensate within the chamber or space (e.g., of the housing portion 104) can also be recollected into the same shelf unit 101. Advantageously, by generating steam closer to the adsorbent article 106, heat loss can be reduced, the insulation design can be improved, and more precise control can be achieved. The cold water also helps to cool the chamber or space (e.g., of the housing portion 104) and shorten the cycle time.

[0098] In some examples, the heating element 504 can include integrated heating of a single adsorbent article 106 within the packaging of the adsorbent article 106. For example, an integrated flexible resistive heater (with holes) can serve as active insulation to reduce the need to heat individual chambers within the housing portion 104. The heating element 504 can also take the form of a jacket disposed around all or part of the adsorbent article 106. Advantageously, preheating the adsorbent article 106 can also reduce condensate. In some examples, as Figure 5B indicated by the thick arrows, the steam is directed either upward or downward.

[0099] As Figure 6A and Figure 6B shown, in some examples, the DAC device 100 includes a shelf unit 101 that includes an adsorbent article 106 such that the first support element or separator 108 and / or the second support element or separator 110 can be formed as or include a plurality of rods or tubes, and each rod or tube can be hollow and define an internal channel 200 used during the adsorption and desorption processes. In some examples, cold water can flow through an active insulation mechanism 604 attached to the outside of the frame structure 102 of the shelf unit 101. The active insulation mechanism can include one or more channels for operating to cool the frame structure in order to cool the desorption medium and form condensate. Additionally, hot steam can flow through the rods or tubes to heat the frame structure in order to facilitate heating of the condensate to provide water vapor within the frame structure. The water vapor can then be provided back to the adsorbent article through holes or openings in the rods or tubes to sustain the adsorption and desorption cycle. In some examples, the openings or perforations 206 can be controllable to be closed or opened as needed at different stages during adsorption and desorption.

[0100] Figure 6CShows a perforation control mechanism 600 which, according to some examples disclosed herein, can be implemented with or coupled to a separator (108 or 110). The separator 108 or 110 has a plurality of openings or perforations 206 which can be opened or closed using the mechanism 600. For simplicity of description, only a portion of the separator 108 or 110 and the mechanism 600 surrounding the relevant perforations 206 are shown in the figures. In some examples, the mechanism 600 can be a smaller tube which is inserted into and disposed within the separator 108 or 110, and the separator 108 or 110 can be a tube or a tubular structure. In some examples, for instance, the mechanism 600 can be a metal piece whose curvature aligns with the inner curvature of the separator 108 or 110. The mechanism 600 also includes a plurality of openings or perforations 602 which are aligned with the positions of the perforations 206 of the separator 108 or 110.

[0101] Thus, when aligned in a first configuration, i.e., the perforations 206 and 602 are aligned with each other, fluid can be allowed to flow through the perforations and into the surrounding environment from within the channel 200. In a second configuration, the perforations 206 and 602 are in a staggered configuration, and the wall of the separator 108 or 110 can block the perforations 602 while the wall of the mechanism 600 can block the perforations 206, thereby preventing fluid from flowing therethrough. The user or device controlling the opening and closing of the perforations can switch between the first (open) configuration and the second (closed) configuration by, for example, twisting and / or sliding the mechanism 600 relative to the separator 108 or 110. Alternatively, the mechanism 600 can include tabs or fins which can be activated to open or close the corresponding perforations 206 in the separator 108 or 110 so as to switch between the first and second configurations.

[0102] In some examples, the frame structure 102 of the shelf unit 101 includes a first set of support members 108 and a second set of support members 110, each set of support members being hollow and defining an internal channel 200 to be used during the adsorption and desorption processes. In some examples, cold water can flow through the first set of support members 108 to cool the frame 102 so as to cool the desorption medium and form condensate. Additionally, hot steam can flow through the first and second sets of support members to heat the frame 102 so as to heat the condensate to provide water vapor inside the frame 102. Then, the water vapor can be provided back into the adsorbent article 106 through holes or openings 206 (not shown) in the second set of support members 110 to continue the adsorption and desorption cycle. In some examples, these openings can be controlled to be closed or opened at different stages during adsorption and desorption as needed.

[0103] In some examples, such as when the old adsorbent material(s) contained inside the shelf unit 101 needs to be replaced with new adsorbent material(s), a single adsorbent article 106 can be removed from the shelf unit 101 and replaced with another adsorbent article 106. The removal and replacement of the adsorbent article 106 can be carried out without removing the entire DAC device 100 from inside the DAC reactor, so that if only one adsorbent article needs to be removed, it can be removed (and subsequently replaced) without affecting one or more of the other cartridges that make up the DAC device 100.

[0104] Figure 7 An example of a shelf unit 101 of a DAC device 100 according to an embodiment disclosed herein is shown. The shelf unit 101 includes a plurality of first support members 108 and second support members 110, where the first support members are substantially vertical and the second support members are substantially horizontal (or angled as shown in the Figure 4 example). The first support members 108 may include a plurality of holes or openings 700 extending through the support members to allow air or fluid to pass between compartments or housing portions 104 defined at least in part by the first and second support members.

[0105] The second support members 110 include an uppermost (top) support member 110A and a lowermost (bottom) support member 110B, such that the support member 110A includes a plurality of "closed" or recessed surfaces 306 (or recessed portions of the surface) without openings therein, as shown in the Figure 3B figure, and these recessed surfaces 306 cause condensate formed on the surface to accumulate in the tip portions of the recessed surfaces 306 in the form of water droplets. The second support members other than the uppermost support member 110A (e.g., the intermediate second support member 110 or the lowermost support member 110B) may each have a surface 208 having perforations 206 pointing downward to form "open" recesses (i.e., configured to direct condensate or water droplets into an internal channel within the support member 110), where the open recesses may have a funnel shape, also as shown in the Figure 3B figure.

[0106] Figure 7 The shelf unit 101 in the [figure] further includes a manifold 202 that is fluidly coupled to the internal channels of the second support members 110. The manifold 202 may be attached to the second support members 110 to form a sidewall of the shelf unit 101, as shown. The manifold 202 includes at least one inlet 204 and at least one outlet 400, through which a desorption medium can be provided and the condensate collected in the internal channels can be directed out of the shelf unit 101, as further shown in the Figure 4 figure.

[0107] Advantageously, switching the steam supply circuit to a cold water circuit can shorten the cycle time. Operating the steam supply system in the wall can provide active insulation and reduce condensation. Cooling water is prevented from flowing out of the steam holes. Individual adsorbent articles may snap into the walls of the shelf unit to increase the circuit while also providing structural support and assisting in the positioning of the adsorbent articles.

[0108] In addition, advantageously, the shelf unit allows for discrete storage of the adsorbent articles. The shelf unit also provides uniform steam distribution to each adsorbent article or modular cartridge of adsorbent articles. Since there is no need for a separate frame for each adsorbent article, the shelf unit makes each adsorbent article less costly to manufacture and transport. In some examples, the shelf unit facilitates cross-flow between the adsorbent articles and thus facilitates collecting water and reusing it as steam (e.g., heated via an external heating device) to achieve a more self-sufficient DAC system while facilitating more efficient drainage, e.g., using the inclined or angled configuration of the shelf unit disclosed herein. In some examples, providing the shelf unit with integrated heating / cooling functionality can cool the steam inside the shelf unit to facilitate efficient formation of water for subsequent adsorption / desorption cycles and / or heat the collected water to facilitate efficient use of the desorption medium for a self-sufficient DAC system.

[0109] The adsorbent materials referred to herein may include any suitable carbon dioxide adsorbent materials, which may include, but are not limited to, ion exchange resins (e.g., strongly basic anion exchange resins such as Dowex TM Marathon TM A resin), zeolites, activated carbon, alumina, metal-organic frameworks, polyethyleneimine (PEI), or other suitable carbon dioxide adsorbent materials such as desiccants, carbon molecular sieves, carbon adsorbents, graphite, activated alumina, molecular sieves, aluminum phosphate, silicoaluminophosphate, zeolite adsorbents, ion-exchanged zeolites, hydrophilic zeolites, hydrophobic zeolites, modified zeolites, natural zeolites, faujasite, clinoptilolite, mordenite, metal-exchanged silicoaluminophosphate, monopolar resins, bipolar resins, aromatic cross-linked polystyrene matrices, brominated aromatic matrices, methacrylate copolymers, graphite adsorbents, carbon fibers, carbon nanotubes, nanomaterials, metal salt adsorbents, perchlorates, oxalates, alkaline earth metal particles, ETS, CTS, metal oxides, chemisorbents, amines, organometallic reagents, hydrotalcites, siliceous rocks, zeolitic imidazolate frameworks, and metal-organic framework (MOF) adsorbent compounds, and combinations thereof, such as further disclosed in U.S. Patent Application No. 18 / 199,506 (Gore & Associates), the disclosure of which is incorporated herein by reference in its entirety for all purposes. Carbon dioxide removal service provider

[0110] This document also discloses a method for removing gaseous carbon dioxide (CO2) from the atmosphere using any suitable means, methods, processes, or devices for atmospheric CO2 removal disclosed herein. In some examples, a carbon dioxide removal service provider, which can be an individual, a device, an atmospheric treatment facility, a carbon dioxide removal plant, software, an Internet website, an electronic interface, an organization or a corporate agent or entity (which may include a control center, a headquarters, a data management center, an intermediary data collection or processing center, or an auxiliary organization that provides information and / or control functions or services to the provider) or an electronic device or display associated with or accessible to the provider, can receive and / or be informed of information regarding the diffusion of a first amount of gaseous CO2 in the atmosphere at a first location. The information can be in complete, partial, derived, or summary form and can be received in the form of an electronic display, an electronic alert, a notification, or other electronic communication (e.g., an email, a phone call, or a video call), and can include numerical data representing the amount of gaseous CO2 (e.g., in tons of CO2) and / or the diffusion rate (e.g., in tons of CO2 per minute, per hour, per day, etc.) diffusing at the first location, as well as data associated with the first location, such as the name of the city and / or country, the GPS location, weather information, etc. In some examples, the information can be in the form of an electronic communication (e.g., a first electronic communication) that includes information regarding the diffusion of a first amount of gaseous CO2 into the atmosphere at the first location, and the information can be received from and / or provided to a computing and / or electronic display device.

[0111] A carbon dioxide removal service provider may separate or otherwise separate a second quantity of gaseous CO2 at a second location, which may be different from the first location, either immediately or at a later stage. The second location may be remote from the first location. For example, when the first location is in a densely populated commercial area, the second location may be near a geothermal or other hazardous energy source that powers the separation process at the second location. The second quantity may be at least a portion of the first quantity, such as from 0% to 10%, from 10% to 20%, from 20% to 30%, from 30% to 40%, from 40% to 50%, from 50% to 60%, from 60% to 70%, from 70% to 80%, from 80% to 90%, from 90% to 100%, or any other suitable value, combination, or range therebetween. The second quantity may be a portion or all of the first quantity, and the second quantity may be associated with a partial delivery of a carbon removal service involving multiple separation cycles. The separation may include any suitable method or process disclosed herein, or use any suitable apparatus disclosed herein. In some examples, the separation may be initiated by sending or transmitting instructions or confirmations to a location having the ability to perform such separation. In some examples, the separation may be performed by a carbon capture device capable of performing any method of separating gaseous CO2 from a gas mixture in the form of ambient air disclosed herein. In some examples, the distance from the first location to the second location may be from 100 kilometers to 200 kilometers, from 200 kilometers to 500 kilometers, from 500 kilometers to 800 kilometers, from 800 kilometers to 1000 kilometers, from 1000 kilometers to 2000 kilometers, from 2000 kilometers to 3000 kilometers, from 3000 kilometers to 4000 kilometers, from 4000 kilometers to 5000 kilometers, from 5000 kilometers to 6000 kilometers, from 6000 kilometers to 7000 kilometers, from 7000 kilometers to 8000 kilometers, from 8000 kilometers to 9000 kilometers, from 9000 kilometers to 10000 kilometers, from 10000 kilometers to 15000 kilometers, from 15000 kilometers to 20000 kilometers, or any other suitable value or range therebetween.

[0112] A carbon dioxide removal service provider may initiate reporting data regarding a second quantity that has been, is being, or will be removed from the atmosphere. The initiation of the reporting may be a preliminary step for immediate or subsequent reporting of data that may be transmitted via any suitable electronic communication or data transfer means, which may be wired or wireless. In some examples, the reporting may involve preparing information to be incorporated into such a report or a subsequent report, and subsequently sending or transmitting instructions or confirmations to another entity or device having the ability to initiate or fully execute such a report. The data reported may relate to the carbon capture device disclosed herein and pertain to the second quantity. For example, the carbon capture device may generate or provide data associated with separating the second quantity of gaseous CO2, which may be obtained directly or indirectly (e.g., via an intermediate entity or device) from the carbon capture device. In some examples, at least a portion of the data generated by the carbon capture device is provided in the form of an electronic communication. As another example, the data may be aggregated or otherwise processed such that an indication of the data is provided in an electronic communication (e.g., a second electronic communication). In some examples, the second electronic communication may be transmitted to a computing or display device. In some examples, the second electronic communication may be transmitted to another computing or display device separate or different from the aforementioned computing or display device.

[0113] In some examples, a method of removing gaseous CO2 from the atmosphere may involve a carbon dioxide removal service provider (as described above), which may receive and / or be informed of information regarding a first quantity of gaseous CO2, which may include the dispersion of the gaseous CO2. The information may be in complete, partial, derived, or summary form and may be received in the form of an electronic display, electronic alert, notification, or other electronic communication (e.g., email, phone call, or video call), and may include numerical data representing the quantity of gaseous CO2 dispersed at a first location (e.g., in tons of CO2) and / or the dispersion rate (e.g., in tons of CO2 per minute, per hour, per day, etc.), as well as data related to the first location, such as the name of a city and / or country, GPS location, weather information, etc. Such quantity may represent the quantity of gaseous CO2 dispersed at a location (e.g., in tons of CO2) and / or the dispersion rate (e.g., in tons of CO2 per minute, per hour, per day, etc.). In some examples, the information may be received as an electronic communication from another entity or device, as disclosed herein, that sends or transmits instructions regarding gaseous CO2 removal. In some examples, an electronic communication (e.g., a first electronic communication) may include information regarding the dispersion of the first quantity of gaseous CO2, which may be received and / or provided to a computing and / or electronic display device.

[0114] A carbon dioxide removal service provider may separate or initiate the separation of a second quantity of gaseous CO2 from the atmosphere, where the second quantity is at least a portion of the first quantity, such as from 0% to 10%, from 10% to 20%, from 20% to 30%, from 30% to 40%, from 40% to 50%, from 50% to 60%, from 60% to 70%, from 70% to 80%, from 80% to 90%, from 90% to 100%, or any other suitable value, combination, or range therebetween.

[0115] A carbon dioxide removal service provider may report data regarding the second quantity that will be removed, is being removed, or has been removed from the atmosphere. The reporting of the data may be carried out via any suitable means of electronic communication or data transfer, which may be wired or wireless. In some examples, the reporting may be in response to receiving an instruction or confirmation message from another entity or device that has the ability to initiate or fully execute such reporting. The data reported may be related to the carbon capture device disclosed herein and pertain to the second quantity. For example, the carbon capture device may generate or provide data related to the separation of the second quantity of gaseous CO2, and such data may be obtained directly or indirectly (e.g., via an intermediate entity or device) from the carbon capture device. In some examples, at least a portion of the data generated by the carbon capture device is provided in the form of an electronic communication. As another example, the data may be aggregated or otherwise processed to provide an indication of the data in an electronic communication (e.g., a second electronic communication). In some examples, the second electronic communication may be transmitted to a computing or display device. In some examples, the second electronic communication may be transmitted to another computing or display device, which may be separate or different from the aforementioned computing or display device.

[0116] In some examples, a method of removing gaseous CO2 from the atmosphere may involve a carbon dioxide removal service provider (as described above), which may transmit, emit, or send information about the dispersion of a first amount of gaseous CO2 into the atmosphere at a first location. The information may be in complete, partial, derived, or summary form, and may be received in the form of an electronic display, electronic alert, notification, or other electronic communication (e.g., email, phone call, or video call), and may include numerical data representing the amount of gaseous CO2 dispersed at the first location (e.g., in tons of CO2) and / or the dispersion rate (e.g., in tons of CO2 per minute, per hour, per day, etc.), as well as data related to the first location, such as the name of the city and / or country, GPS location, weather information, etc. The transmission may be an emission and / or sending via any suitable electronic communication or data transfer means, which may be wired or wireless, and may not be received by the intended recipient or any recipient. In some examples, the information may be in the form of an electronic communication (e.g., a first electronic communication) that includes information about the dispersion of a first amount of gaseous CO2 into the atmosphere at a first location, and this information may be transmitted, emitted, and / or sent to a computing device, and this transmission, emission, and / or sending may not necessarily be received by any recipient.

[0117] A carbon dioxide removal service provider may request the immediate or subsequent separation of a second quantity of gaseous CO2 from the atmosphere at a second location, or a method for separating a second quantity of gaseous CO2 from the atmosphere. The second location may be remote from the first location. For example, when the first location is in a densely populated commercial or industrial area, the second location may be near a geothermal energy source or other hazardous energy source that powers the separation process at the second location. The second quantity may be at least a portion of the first quantity, such as from 0% to 10%, from 10% to 20%, from 20% to 30%, from 30% to 40%, from 40% to 50%, from 50% to 60%, from 60% to 70%, from 70% to 80%, from 80% to 90%, from 90% to 100%, or any other suitable value, combination, or range therebetween. The second quantity may be a portion or all of the first quantity, and the second quantity may be associated with a partial delivery of a carbon removal service involving multiple separation cycles. The separation may include any suitable method or process disclosed herein, or use any suitable apparatus disclosed herein. The request for separation or the initiation of separation may be via any suitable means of electronic communication or data transfer, which may be wired or wireless. In some examples, the request operation may be implemented by sending, issuing, or transmitting a start instruction to a location capable of initiating or fully executing such separation. In some examples, the separation may be performed by a carbon capture device capable of performing any method disclosed herein for separating gaseous CO2 from a gas mixture in the form of ambient air. In some examples, the distance between the first location and the second location may be from 100 kilometers to 200 kilometers, 200 kilometers to 500 kilometers, 500 kilometers to 800 kilometers, 800 kilometers to 1000 kilometers, 1000 kilometers to 2000 kilometers, 2000 kilometers to 3000 kilometers, 3000 kilometers to 4000 kilometers, 4000 kilometers to 5000 kilometers, 5000 kilometers to 6000 kilometers, 6000 kilometers to 7000 kilometers, 7000 kilometers to 8000 kilometers, 8000 kilometers to 9000 kilometers, 9000 kilometers to 10000 kilometers, 10000 kilometers to 15000 kilometers, 15000 kilometers to 20000 kilometers, or any other suitable value or range therebetween.

[0118] A carbon dioxide removal service provider may receive reports, indications of such reports, and / or indications of the availability of data regarding a second quantity that has been, is being, or will be removed from the atmosphere. Receiving a report does not require manual review or verification and can be achieved simply by making the report accessible, even if it is never subsequently reviewed or confirmed, and / or can be via any suitable means of electronic communication or data transfer, which can be wired or wireless. In some examples, receiving a report may relate to the second quantity, such as how much gaseous CO2 has been sequestered over a predetermined period of time, such as a day, a week, a month, etc. Regarding the second quantity, the reported data may relate to the carbon capture devices disclosed herein. For example, a carbon capture device may generate or provide data related to sequestering the second quantity of gaseous CO2, and such data can be obtained directly or indirectly (e.g., via an intermediate entity or device) from the carbon capture device. In some examples, at least a portion of the data generated by the carbon capture device is provided in the form of electronic communication. As another example, the data may be aggregated or otherwise processed such that an indication of the data is provided in an electronic communication (e.g., a second electronic communication). In some examples, the second electronic communication is received from a computing device. In some examples, the second electronic communication is received in response to a first electronic communication. In some examples, the second electronic communication is received from a computing or display device in response to sending a first electronic communication to the computing or display device.

[0119] As used herein, "receiving" information should be understood to require only one party (or entity, device, etc.) to perform the "receiving" action, and thus does not require another party to perform a "sending" action.

[0120] In this document, the "initiation" of separation (or separation method) should be understood as an "initiation" act, including the preliminary or completed act of issuing an instruction to another party or another device, with the intention of performing or starting the separation process, or associating the already started separation process with the initiation step. For example, the act of "initiating" the separation of gaseous CO2 may cause the carbon capture device to subsequently receive, directly or indirectly (e.g., via an intermediate entity or device), an instruction to initiate the separation, and the carbon capture device will operate accordingly. In another example, the act of "initiating" the separation of gaseous CO2 (or separation method) may include the carbon dioxide removal service provider associating the carbon dioxide that has been removed from the atmosphere (or is currently in the active removal process) with the subsequent initiation of separation. It should be understood that the instruction received by the carbon capture device does not need to be provided as part of such an "initiation" operation. In addition, for example, the act of "separation" of CO2 is not necessarily part of such an "initiation" act of separation, such as when the "initiation" of separation is performed by a first party, and the subsequent "separation" itself is performed by a second party different from the first party. In addition, the "separation" act does not need to be completed or fully completed by the first party or the second party. It should also be understood that even if the confirmation of initiation or post-initiation acts or acts related to initiation occur in different jurisdictions or countries, the initiation act can still be fully completed within one jurisdiction or country.

[0121] In this document, the "initiation" of a report (such as a data report) should be understood as an "initiation" act, including the preliminary or complete preparation of an instruction or sending an instruction to another party for it to prepare, start, or complete a report at a later time. Thus, for example, when the act of "initiating" a report is performed by a first party (the initiator), and the "reporting" itself is performed by a second party (the reporter) different from the first party (the initiator), the act of "reporting" any data is not necessarily part of the act of "initiating" such a report. In addition, the "reporting" act does not need to be completed or fully completed by the first party or the second party. It should be understood that even if the confirmation of the initiation act or acts related to or subsequent to the initiation act occur in different jurisdictions or countries, the initiation act can still be fully performed within one jurisdiction or country.

[0122] In this document, the "reporting" of data should be understood as a "reporting" act, which may only require one party (the reporter) to perform. In addition, the "reporting" act does not require the other party (the recipient) to receive (or confirm receipt) of such a report. The report can be the storage of data or the display of data at a location accessible to the intended recipient, and even if the intended recipient does not access or view the data, it can still be considered a report.

[0123] In this document, the "transmission" of information should be understood as a "transmission" act, which may only require one party (the transmitter) to perform. In addition, the "transmission" act does not require the recipient (such as the recipient) or receipt confirmation (such as confirmation of receipt) of the transmitted information.

[0124] In this document, a "request" for separation (or initiation of a separation method) should be understood as a "request" action that may be performed by only one party (the requesting party). Additionally, the "separation" action required by the "request" action may be performed by another party (the separating party). Furthermore, the "request" action may only be an intention or a start and does not need to be completed or fully realized (e.g., when no separation result is produced by the "request" action). In one example, the act of "requesting" separation (or initiation of a separation method) of gaseous CO2 may include an association by a carbon dioxide removal service provider of carbon dioxide that has been removed from the atmosphere (or is currently undergoing active removal processing) with a subsequent separation request. It should be understood that even if the confirmation of the request or actions subsequent to or related to the request occur in a different jurisdiction or country, the request action can still be fully performed within one jurisdiction or country.

[0125] In this document, a "receiving" of a report or indication of a report should be understood as a "receiving" action that does not require a sender (such as a sender). Receiving can be the storage of data or the display of data at a location accessible to the intended recipient, and even if the intended recipient does not access or view the data, it can still be considered received.

[0126] It can be understood that the first quantity, the second quantity, and a portion of the first quantity can be estimated or predicted values. It can further be understood that the carbon dioxide gas released or dispersed at the first location may not necessarily include the same CO2 molecules separated or collected at the second location, and the second quantity can be an equivalent quantity of the CO2 released or dispersed. The CO2 in a portion of the first quantity can be in a non-gaseous form. A portion of the first quantity or the second quantity can refer to the carbon dioxide captured by an adsorbent disclosed herein, or carbon dioxide that has been stored or otherwise converted to another form. A portion of the first quantity or the second quantity can also include gases other than carbon dioxide. For example, the second quantity can be in a non-gaseous form or combined with other substances.

[0127] As used herein, a "carbon capture device" refers to any one or more devices disclosed herein that are capable of separating gaseous CO2 from the atmosphere at the location where the device is installed or placed. A carbon capture device can refer to a single device or multiple devices, or it can refer to a facility that includes one or more such devices or component devices that work together. The device can include, for example, a desorbing medium source and an adsorber structure disclosed herein. The device can be operated by a user or operator using an electronic device. The device can generate data related to its operation, such as data that can be detected by one or more sensors and / or data that can include log data, etc.

[0128] As used herein, an "electronic device" refers to a device capable of performing one or more electronic operations, such as a computer, a smart phone, a smart tablet, etc. The electronic device may include, for example, a display device and / or one or more processing units and one or more storage units. The processing unit may include a central processing unit (CPU), a microprocessor, a system on a chip (SoC), or any other processor capable of performing such operations. The storage unit may be a non-transitory computer-readable storage medium on which one or more programs or instructions are stored, and when these programs or instructions are run on the processing unit, the processing unit or the electronic device is caused to perform one or more methods disclosed herein. The storage unit may include one or more storage chips capable of storing data and allowing the processing unit to access storage locations, such as volatile or non-volatile memory, static or dynamic random access memory, or any variant thereof. In some examples, the electronic device may be referred to as a computing device.

[0129] The technical advantages of removing gaseous CO2 from the atmosphere using the methods or processes disclosed herein include, but are not limited to: facilitating the network interconnection between entities and / or devices that are capable of communicating with other entities and / or devices in order to remotely provide instructions or facilitate the separation and removal of gaseous CO2 without the need to operate on-site in person. Additionally, the methods and processes disclosed herein provide a robust cross-institutional communication network such that each entity (which may be an institution associated with a physical location) can simultaneously direct or initiate the separation and removal of gaseous CO2 at multiple locations and can flexibly change the locations at which the separation and removal of gaseous CO2 are determined to occur. The change in location can be made in real time or near real time, for example, such that there is a minimal time lag between the issuance of an instruction and the separation of gaseous CO2 at a specified location. In some examples, the methods or processes disclosed herein provide a flexible communication network in which the entity or device performing the separation and removal of gaseous CO2 at a specified location can provide timely reports (such as an operation summary and / or a service invoice) related to the amount of gaseous CO2 removed within a predetermined time period. Such reports can be generated automatically or manually, can be generated at predetermined time intervals (such as daily, weekly, monthly, etc.), can be generated more flexibly according to a manually determined manner (such as each time a user or entity requests), or can be generated in response to reaching or exceeding a predetermined threshold, including but not limited to the amount of gaseous CO2 separated and removed from the atmosphere (such as every 1 ton, 5 tons, 10 tons, etc. of gaseous CO2 removed from the atmosphere) and any other suitable conditions determined and agreed upon by the relevant entities.

[0130] Various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the disclosure. For example, although the embodiments described above relate to specific features, the scope of the disclosure also includes embodiments having different combinations of features and embodiments that do not include all of the described features. Accordingly, the scope of the disclosure is intended to cover all such alternatives, modifications, and variations that fall within the scope of the claims, as well as all of their equivalents.
