The subject matter of these related applications is hereby incorporated herein by reference. Technical Field

[0003] Various embodiments relate generally to carbon capture technology and, more particularly, to low power direct air carbon capture systems.

[0004] Related technical description

[0005] According to many scientific studies, global warming is becoming a serious problem for present and future generations. Many people advocate that the main contributing factor to global warming is the human extension of the "greenhouse effect", in which the earth's atmosphere intercepts the heat that would otherwise radiate from the earth to space. The different gases that contribute to the greenhouse effect (referred to herein as "greenhouse gases") include water vapor, methane, nitrous oxide and carbon dioxide. Many scientists believe that the most serious effects of global warming can be prevented by reducing greenhouse gas emissions based on human beings and reducing the concentration of greenhouse gases in the current earth's atmosphere. For this reason, a technology that is being developed to solve global warming is direct air carbon capture, in which carbon dioxide is captured and removed from the earth's atmosphere.

[0006] Direct air carbon capture generally involves attempts to remove large amounts of carbon dioxide from the Earth's atmosphere through an adsorption / desorption process. In many direct air carbon capture embodiments, ambient air is exposed to a suitable adsorbent, such as an amine-based material, which adsorbs carbon dioxide present in the ambient air. The adsorbed carbon dioxide is then released from the adsorbent via a desorption process for subsequent storage.

[0007] In order for direct air carbon capture or any other process to be a viable method of reducing the greenhouse effect, the process of removing carbon dioxide from the Earth's atmosphere needs to result in negative greenhouse gas emissions. That is, the amount of greenhouse gases produced when producing the energy required to affect the direct air carbon capture process must be less than the amount of greenhouse gases removed from the Earth's atmosphere by the direct air carbon process.

[0008] One disadvantage of conventional direct air carbon capture processes is that these processes typically require large amounts of energy, including thermal energy required to release the carbon dioxide during the desorption process, and fan energy typically required to direct ambient air over the adsorbent material. Therefore, in order to achieve a negative greenhouse gas emission process, direct air carbon capture facilities are typically located at or near large renewable energy sources, such as geothermal reservoirs, solar power plants, or wind farms. Such location constraints prevent conventional direct air carbon capture processes from being widely implemented, which limits the effectiveness of direct air carbon capture in combating global warming. In addition, direct air carbon capture facilities are typically quite large, with a footprint on the order of a commercial building, which limits the locations where these facilities can be built and the number of these facilities that can be built.

[0009] As previously noted, what is needed in the art is more efficient technology for direct air carbon capture. Summary of the invention

[0010] According to various embodiments, a direct air carbon capture system includes: a wind turbine including at least one blade, the at least one blade including one or more openings, wherein in operation, a first air flows through the at least one blade, causing the wind turbine to generate electrical energy, and causing the one or more openings to receive a second air; a conduit fluidly coupling the one or more openings to carbon dioxide (CO 2 ) adsorption chamber, the adsorption chamber comprising one or more amino CO 2 adsorber, in which, during operation, CO 2 The adsorption chamber receives a second air through one or more openings; and a carbon desorption device that removes the second air from the one or more amine-based CO 2 Adsorber desorbs CO 2 .

[0011] At least one technical advantage of the disclosed design over the prior art is that the disclosed design achieves direct air carbon capture, which does not require external energy sources or large centralized renewable energy sources. In addition, the disclosed design achieves a direct air carbon capture process that does not rely on large amounts of fan energy. Therefore, relative to prior art designs and technologies, the direct air carbon capture process requires less overall energy consumption and can be net greenhouse gas negative. These technical advantages provide one or more technical advances over prior art methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] CO on the outside of turbine blades 2 Adsorption

[0021] Figure 1 is a conceptual illustration of a direct air carbon capture system 100 configured to implement one or more aspects of various embodiments. The direct air carbon capture system 100 removes carbon dioxide (CO 2), the direct air carbon capture process is powered by electrical energy 113 generated by a wind turbine 110. In some embodiments, little or no fan energy is consumed as part of the direct air carbon capture process, thereby increasing the overall negative greenhouse gas emissions of the process. As shown, the direct air carbon capture system 100 includes a wind turbine 110 having one or more blades 111 and a generator 112. When ambient air 106 flows over the blades 111 and the blades 111 rotate, the generator 112 generates electrical energy 113. In Figure 1 In the illustrated embodiment, one or more openings 104 are formed in the surface of each turbine blade 111 for receiving CO2-containing air as wind 101 flows over blade 111. 2 The direct air carbon capture system 100 also includes CO 2 Adsorption chamber 120 and CO 2 Desorption device 130.

[0022] exist Figure 1 In the illustrated embodiment, the direct air carbon capture system 100 includes one or more conduits 105 that fluidly couple one or more openings 104 to the CO 2 Adsorption chamber 120. In some embodiments, one or more ducts 105 may include a rotating manifold 108 that fluidly connects, for example, a stationary duct 105 within a nacelle 114 of a wind turbine 110 to one or more ducts 105 that rotate about the nacelle 114, such as a duct 105 disposed within each blade 111. In such embodiments, the rotating manifold 108 provides a rotatable connection between the nacelle 114 and the blades 111, thereby enabling air received via the opening 104 to flow from the blades 111 to the CO 2 Adsorption chamber 120.

[0023] The wind turbine 110 includes one or more blades 111, such as airfoil blades, and generates electrical energy 113 from the flow of ambient air 106 through the one or more blades 111. The wind turbine 110 can be any technically feasible wind turbine configuration, such as a horizontal axis wind turbine (HAWT) or a vertical axis wind turbine (VAWT). For example, in an embodiment in which the wind turbine 110 is a HAWT, the blades are airfoils assembled to a horizontally oriented rotor coupled to a generator 112. The HAWT enables the blades and rotor to be positioned relatively high above the ground in order to receive higher and more consistent operating wind speeds. Therefore, HAWTs are typically used in large-scale wind farms. In an embodiment in which the wind turbine 110 has a VAWT configuration, the axis of rotation of the turbine is perpendicular to the ground. Unlike a HAWT, a VAWT can be powered by wind from any direction and therefore has the ability to efficiently generate energy under inconsistent and / or variable wind conditions. Therefore, VAWTs are ideal for installations where wind conditions are inconsistent or where turbines cannot be placed high enough to benefit from steady winds, such as small wind projects and residential applications.

[0024] CO 2 The adsorption chamber 120 is configured to remove CO from ambient air by a process 2 , and releases the adsorbed CO through the desorption process 2 for storage and / or storage. To this end, CO 2 Adsorption chamber 120 includes one or more amine-based CO 2 Adsorber 121. In operation, CO 2 The adsorption chamber 120 receives an ambient air flow via the conduit 105, and the CO present in the ambient air 2 Adsorbed to the amino group CO 2 The surface of the adsorber 121. Then during the desorption process, the amine CO 2 Adsorber 121 releases the adsorbed CO 2 In some embodiments, the desorption process is performed by heating the amine CO 2 Adsorber 121 is carried out, for example, by passing CO 2 Steam generated by desorption unit 130 and / or another heating method. In some embodiments, the desorption process is performed by CO 2 The desorption device 130 is carried out.

[0025] Amine CO 2 Adsorber 121 includes a high CO 2 In some embodiments, the amine-based material can be further selected to have low regeneration energy, good cycle performance and high moisture resistance. 2The porous amine-based material in the adsorber 121 may include a high density of micropores, so that the amine-based CO 2 Adsorber 121 has a high specific surface area. In some embodiments, the amine-based CO 2 The amine-based material in the adsorber 121 makes CO 2 The adsorption was carried out at ambient temperature, and the regeneration of the material during the desorption process was carried out at 80-120 °C to release CO 2 .

[0026] CO 2 The desorber 130 is fluidically and / or thermally coupled to the CO 2 The adsorption chamber 120 and the amine CO 2 Adsorber 121 desorbs CO 2 In some embodiments, CO 2 The desorption device 130 generates steam and directs the steam to the amine CO 2 The adsorber 121 comes from the amine CO 2 Adsorber 121 desorbs CO 2 In such embodiments, steam is generated using electricity 113 generated by wind turbine 110 and water, for example, from a water reservoir (not shown). In some embodiments, during the desorption process, CO 2 The desorption device 130 is fluidly coupled to the CO 2 Adsorption chamber 120, for providing steam to the amino CO 2 On adsorber 121. In some embodiments, the released CO 2 Dissolved in amino CO 2 The condensed steam (liquid water) formed on the surface of the adsorber 121 contains CO 2 Alternatively or additionally, in some embodiments, the released gaseous CO 2 By CO 2 The steam generated by the desorption device 130 rushes into the water storage tank and introduces CO 2 In either case, during the desorption process, the amine-based CO 2 CO in adsorber 121 2 to a water reservoir for subsequent separation and / or storage. Alternatively, in some embodiments, CO 2 The desorption device 130 directly heats the amine-based CO by, for example, via a resistive heater (not shown) powered by electrical energy 113. 2 Adsorber 121 from amine CO 2 Adsorber 121 desorbs CO 2 .

[0027] In some embodiments, CO 2 Desorption device 130 and / or CO 2 The adsorption chamber 120 is fluidly coupled to a housing for sequestering and / or storing CO removed from the ambient air 106 processed by the direct air carbon capture system 100. 2 107 (not shown). In some embodiments, the gas phase CO 2 is captured by the direct air carbon capture system 100 and separated into carbon and oxygen. Alternatively or additionally, in some embodiments, the CO 2 The water is produced by the direct air carbon capture system 100. In such embodiments, the direct air carbon capture system 100 may be fluidly coupled to a system for injecting a CO 2 A water system (not shown) in which CO 2 Permanently removed from the biosphere through mineralization processes.

[0028] In operation, a portion of ambient air 106 flowing over blades 111 is received by opening 104, which is fluidly coupled to the CO via one or more conduits 105. 2 Adsorption chamber 120. Openings 104 are positioned on one or more surfaces of each blade 111 so that ambient air 106 incident on openings 104 is received by openings 104 and flows through conduits 105 to the CO 2 Adsorption chamber 120. To this end, in some embodiments, opening 104 is disposed on a specific portion of the surface of each blade 111 that causes such airflow. Specifically, the specific portion of the surface may be a portion of the blade surface that fluidly contacts the high pressure area generated by blade 111 when ambient air 106 flows through blade 111. Figure 2 Embodiments of the location of the opening 104 are described.

[0029] Figure 2 Schematically depicts a cross section of a blade 111 of a wind turbine 110 according to various embodiments. Typically, the wind turbine 110 is oriented toward the flow direction of the ambient air 106, and the blades 111 are oriented at a specific blade angle so that the ambient air 106 has a relative velocity 206 that results in a suitable angle of attack 201 for the blades 111, which is the angle at which the ambient air 106 approaches the blades 111. Figure 2 Also shown is a resulting pressure distribution 220 on the surface of blade 111 when ambient air 106 flows over blade 111 at angle of attack 201 , with high pressure represented by solid arrows and low pressure represented by dashed arrows.

[0030] According to various embodiments, the opening 104 (in Figure 1104) is disposed on one or more surfaces that fluidly contacts a high pressure region 202 generated by the blade 111 when the ambient air 106 flows over the blade 111 at an angle of attack 201. In some embodiments, one or more openings 104 are disposed on a portion of a leading edge 211 of the blade 111, on a portion of a trailing edge 212 of the blade 111, and / or on any other surface of the blade 111 that fluidly contacts a high pressure region 202.

[0031] It should be noted that the angle of attack 201 is a combination of the free stream speed of the ambient air 106 and the rotational speed of the blade 111. Because the blade tip (not shown) necessarily travels farther than the blade root (not shown) for each rotation, the rotational speed of the cross section of the blade 111 increases from the blade root to the blade tip. Therefore, the blade 111 is generally twisted from the root to the tip to achieve an optimal value or near an optimal value for the angle of attack 201 and thereby improve lift generation along the length of the blade 111. Therefore, Figure 2 The sectional view shown in FIG. 1 shows a cross section of the blade 111 at a single location between the blade root and the blade tip. Figure 2 The example of the resulting pressure distribution 220 shown in corresponds to this single location.

[0032] Because the relative velocity between the ambient air 106 and the blades 111 is highest at or near the tips of the blades 111, in some embodiments, the openings 104 are disposed near the tips of the blades 111. Additionally, in some embodiments, the ducts 105 within each blade 111 have a cross-sectional area that tapers from a larger cross-sectional area near the tip of the blade 111 to a smaller cross-sectional area near the root of the blade 111.

[0034] Figure 3 is a conceptual illustration of a direct air carbon capture system 300 configured to implement one or more other aspects of various embodiments. Similar to direct air carbon capture system 100, direct air carbon capture system 300 removes carbon dioxide (CO 2 ), the direct air carbon capture process is powered by electrical energy 313 generated by a wind turbine 310. In some embodiments, little or no fan energy is consumed as part of the direct air carbon capture process, thereby increasing the overall negative greenhouse gas emissions of the process. As shown, the direct air carbon capture system 300 includes a wind turbine 310 having one or more blades 311 and a generator 312. When ambient air 106 flows over the blades 311 and the blades 311 rotate, the generator 312 generates electrical energy 313. In Figure 3 In the embodiment shown, the amine group CO2 Adsorber 321 and CO 2 A desorption device 330 is arranged in each turbine blade 311 .

[0035] Amine CO 2 Adsorber 321 includes Figure 1 The amino CO 2 The amine-based material included in the adsorber 121 is a porous amine-based material. Figure 3 In the embodiment shown, the amine group CO 2 Adsorber 321 forms at least a portion of the surface of one or more blades 311. For example, in some embodiments, the amine CO 2 The adsorber 321 forms part of the wall of one or more blades 311 .

[0036] CO 2 The desorption device 330 extracts the amine CO 2 Adsorber 321 desorbs CO 2 In some embodiments, CO 2 The desorption device 330 includes a steam source 331, a heating element 332, and / or a vacuum generating device 333. In some embodiments, CO 2 The desorption device 330 is powered by the electric energy 313 generated by the generator 312. Figure 3 In the embodiment shown, at least one CO 2 The desorption device 330 is disposed in each blade 311. The steam source 331 generates steam and guides the steam to the amino CO 2 As part of the desorption process on or in adsorber 321. Thus, the steam heats the amine CO 2 Adsorber 321, so that CO 2 307 is released therefrom. The released CO is then, for example, released via a vacuum generating device 333 2 307 from amino CO 2 The amine CO is removed from the adsorber 321. Alternatively or additionally, in some embodiments, as part of the desorption process, the amine CO 2 Adsorber 321 is heated via heating element 332. In such embodiments, the amine CO 2 CO released from adsorber 321 2 307 is captured by vacuum generator 333. Vacuum generator 333 can be a vacuum pump or a vacuum pump for generating negative pressure and removing the amine CO 2 Adsorber 321 captures CO during release 2 307 other devices.

[0037] In operation, the direct air carbon capture system 300 removes CO from the ambient air 106.2 307 for storage or sealing. Specifically, when the ambient air 106 passes through the amino CO 2 When the adsorber 321 is formed on the surface of the blade 311, CO 2 Amine CO 2 The adsorber 321 adsorbs. Subsequently, the adsorbed CO 2 From the amino CO 2 The CO2-based gas is desorbed from the adsorber 321 (e.g., via a steam source 331 and / or a heating element 332) and removed from the blades 311 (e.g., via a vacuum generator 333). It should be noted that fan energy is not used to generate CO2-based gas. 2 Ambient air continuously flows through the amino CO 2 Adsorber 321.

[0038] In some embodiments, CO 2 The desorption device 330 includes a removable CO 2 Desorption device, when the CO 2 When the desorption device moves to different positions in the blade 311, the desorption device can be 2 Different parts of adsorber 321 desorb CO 2 The following combination Figure 4 One such embodiment is described.

[0039] Figure 4 is a removable CO according to various embodiments 2 A more detailed illustration of the desorption device 400. The mobile CO 2 The desorption device 400 is disposed within a wind turbine blade 411 of a wind turbine and is positioned against a surface 431 of a wall 401 of the wind turbine blade. As shown, the wall 401 of the blade 411 comprises an amine-based CO 2 The adsorber 321 is or is formed thereof, which removes CO from the ambient air flowing through the wind turbine blades 411. 2 In operation, actuator 409 moves movable CO along surface 431. 2 Desorption device 400 allows different parts of wall 401 to undergo the desorption process. Figure 4 In the embodiment shown, the CO 2 The desorption device 400 includes a steam source 331 and a vacuum generating device 333. As shown in the figure, the steam source 331 guides the steam against the surface 431 and / or guides the steam to the amine CO 2 The adsorber 321 and the vacuum generator 333 capture the CO from the amine groups. 2 CO released from adsorber 321 2 407. Captured CO 2 407 is connected to the removable CO via a fluid2 The conduit 405 of the desorption device 400 is collected for sequestration or storage.

[0040] In some embodiments, the desorption process is performed periodically, for example during wind turbine idle time. In other embodiments, the desorption process is performed continuously. In such embodiments, the CO 2 The desorption device 400 can be continuously moved along the surface 431 to remove the amine CO 2 Partial desorption of CO in adsorber 321 2 and capture the desorbed CO 2 .

[0041] In some embodiments, CO 2 The desorption device 330 includes a fixed CO 2 Desorption device, which can remove CO from amine groups 2 Adsorber 321 desorbs CO 2 The following combination Figure 5 One such embodiment is described.

[0042] Figure 5 CO according to various other embodiments 2 A more detailed illustration of the desorption device 500. 2 The desorption device 500 is arranged in the wall 501 of a wind turbine blade 511, which includes an amino CO 2 The adsorber 321 is or is formed thereof. Specifically, CO 2 The desorption device 500 includes one or more heating elements 502 and one or more conduits 505 disposed within a wall 501. In some embodiments, the one or more conduits 505 include capillaries or other small channels for enhancing the desorption of CO. 2 In some embodiments, conduit 505 is fluidically coupled to a vacuum generating device, such as Figure 3 Alternatively, in some embodiments, the vacuum generating device is fluidly connected to the internal region 503, and the desorbed CO 2 The transport from the wind turbine blade 511 is via the inner region 503 rather than the duct 505 .

[0043] In some embodiments, the heating element 502 is formed by placing an amine group CO 2 The adsorber 321 is heated to a suitable desorption temperature to periodically desorb the amino CO 2 Adsorber 321 performs the desorption process. In some embodiments, the amine CO 2 Adsorber 321 associated CO 2 The desorption temperature of adsorbed CO 2 Overcoming CO2 Keep adsorbed to the amine CO 2 The temperature of the activation barrier or binding energy of the surface of the adsorber 321 .

[0044] In summary, the various embodiments shown and provided herein set forth techniques for a low energy direct air carbon capture process powered using electrical energy generated by a wind turbine. Specifically, the relative velocity between the ambient air flow and the surface of the wind turbine blades causes the air incident on the openings formed in the surface to flow to the CO 2 desorption device without using fans or consuming fan energy. In addition, CO 2 The desorption unit is powered by electricity generated by a wind turbine.
