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

Technical Field

[0002] Various embodiments generally relate to carbon capture technologies, and more particularly to low - power direct air carbon capture systems.

Background Art

[0003] According to many scientific studies, global warming is becoming a serious problem for both current and future generations. Many assert that the main cause of global warming is the human - induced expansion of the "greenhouse effect". In the "greenhouse effect", the Earth's atmosphere traps heat that would otherwise radiate from the Earth into outer space. The various 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 impacts of global warming can be prevented by reducing human emissions of greenhouse gases and decreasing the concentration of greenhouse gases currently present in the Earth's atmosphere. For that purpose, one technology that has been developed to address global warming is direct air carbon capture, which captures carbon dioxide and removes it from the Earth's atmosphere.

[0004] Direct air carbon capture typically involves attempts to remove large amounts of carbon dioxide from the Earth's atmosphere by an adsorption / desorption process. In many embodiments of direct air carbon capture, ambient air is exposed to a suitable adsorbent, such as an amine-based material, that adsorbs the carbon dioxide present in the ambient air. The adsorbed carbon dioxide is then released from the adsorbent via a desorption process for subsequent storage.

[0005] For direct air carbon capture or any other process to be a viable approach for reducing the greenhouse effect, the process of removing carbon dioxide from the Earth's atmosphere must result in a negative emissions of greenhouse gases. That is, the amount of greenhouse gases generated when producing the energy required to operate 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 capture process.

[0006] One drawback of conventional direct air carbon capture processes is that they typically require substantial energy, including the thermal energy necessary to liberate carbon dioxide in the desorption process and, in many cases, the energy of fans necessary to direct ambient air towards the adsorbent material. Thus, to achieve a negative greenhouse gas emissions process, direct air carbon capture facilities are typically located at or near large-scale sources of renewable energy, such as geothermal reservoirs, solar power plants, or wind farms. These locational constraints prevent the widespread implementation of conventional direct air carbon capture processes and thus limit the effectiveness of direct air carbon capture in the fight against global warming. Additionally, direct air carbon capture facilities are typically very large and have a commercial building-sized footprint, and thus the locations where these facilities can be built and the number of such facilities that can be built are limited.

[0007] As described above, what is needed in the art is a more effective technology for direct air carbon capture. SUMMARY OF THE INVENTION

[0008] According to various embodiments, an atmospheric carbon direct capture system comprises a wind turbine having at least one blade including one or more openings, wherein during operation, a first air flows across the at least one blade to generate electrical energy in the wind turbine and allows a second air to enter the one or more openings; a conduit fluidly coupling the one or more openings to a carbon dioxide (CO2) adsorption chamber including one or more amine-based CO2 adsorbents, wherein during operation, the CO2 adsorption chamber receives the second air through the one or more openings; and a carbon desorption device for desorbing CO2 from the one or more amine-based CO2 adsorbents.

[0009] Compared with the prior art, at least one technical advantage of the disclosed design is that the disclosed design enables direct capture of atmospheric carbon without requiring an external energy source or a large-scale centralized renewable energy source. Further, the disclosed design enables an atmospheric carbon direct capture process that does not rely on a huge amount of fan energy. Thus, the atmospheric carbon direct capture process consumes less total energy and may result in a net negative greenhouse gas effect compared with the prior art designs and technologies. These technical advantages provide one or more technical improvements over the prior art approaches.

[0010] To enable a more detailed understanding of the above features of the various embodiments, a more specific description of the inventive concept briefly summarized above may be made by reference to the various embodiments, some of which are illustrated in the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0012] For clarity, where applicable, the same reference numbers are used to designate common identical elements between the drawings. It is contemplated that the features of one embodiment may be incorporated into other embodiments without further description.

[0013] In the following description, numerous specific details are set forth in order to provide a better understanding of various embodiments. However, it will be apparent to those skilled in the art that the inventive concept can be practiced without one or more of these specific details.

[0014] CO2 adsorption outside the turbine blade FIG. 1 is a conceptual diagram of an atmospheric carbon direct capture system 100 configured to implement one or more aspects of various embodiments. The atmospheric carbon direct capture system 100 removes carbon dioxide (CO2) from ambient air via an atmospheric carbon direct capture process that is powered by electrical energy 113 generated by a wind turbine 110. In some embodiments, the total negative greenhouse gas emissions of this process are increased by the fact that little or no fan energy is consumed as part of the atmospheric carbon direct capture process. As shown, the atmospheric carbon direct capture system 100 includes a wind turbine 110 having one or more blades 111 and a generator 112. The generator 112 generates electrical energy 113 when ambient air 106 flows across the blades 111 and the blades 111 rotate. In the embodiment shown in FIG. 1, one or more openings 104 are formed in the surface of each turbine blade 111 to receive CO2-containing air when the wind 101 flows across the blades 111. The atmospheric carbon direct capture system 100 further includes a CO2 adsorption chamber 120 and a CO2 desorption device 130.

[0015] In the embodiment shown in FIG. 1, the atmospheric carbon direct capture system 100 includes one or more conduits 105 that fluidly couple the one or more openings 104 to the CO2 adsorption chamber 120. In some embodiments, the one or more conduits 105 may include a rotating manifold 108 that fluidly connects a stationary conduit 105 within, for example, the nacelle 114 of the wind turbine 110 to one or more conduits 105 that rotate about the nacelle 114, such as conduits 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, thus enabling the flow of air received through the openings 104 from the blades 111 to the CO2 adsorption chamber 120.

[0016] 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 across the one or more blades 111. Wind turbine 110 may 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 embodiments where wind turbine 110 is a HAWT, the blades are airfoils attached to a horizontally oriented rotor coupled to generator 112. A HAWT allows the blades and rotor to be placed at a relatively high position above the ground, receiving higher and more consistent operating wind speeds. As a result, HAWTs are commonly used in large-scale wind farms. In embodiments where wind turbine 110 has a VAWT configuration, the axis of rotation of the turbine is perpendicular to the ground. Unlike a HAWT, a VAWT is powered by wind coming from any direction and thus has the ability to efficiently produce energy in non-constant and / or variable wind conditions. Therefore, VAWTs are ideal for installation sites with non-constant wind conditions or where the turbine cannot be placed as high to benefit from steady winds, such as weak wind projects and residential applications.

[0017] The CO2 adsorption chamber 120 is configured to remove CO2 from the ambient air via an adsorption process and release the adsorbed CO2 for isolation and / or storage via a desorption process. For that purpose, the CO2 adsorption chamber 120 includes one or more amine-based CO2 adsorbents 121. During operation, the CO2 adsorption chamber 120 receives the flow of ambient air via conduit 105, and the CO2 present in the ambient air is adsorbed onto the surface of the amine-based CO2 adsorbent 121. Next, the adsorbed CO2 is released from the amine-based CO2 adsorbent 121 during the desorption process. In some embodiments, the desorption process is performed by heating the amine-based CO2 adsorbent 121 via steam generated, for example, by a CO2 desorption device 130 and / or another heating method. In some embodiments, the desorption process is performed by a CO2 desorption device 130.

[0018] The amine-based CO2 adsorbent 121 includes a porous amine-based material having a high CO2 adsorption capacity. In some embodiments, the amine-based material can be further selected to have low regeneration energy, good cycle performance, and high moisture resistance. The porous amine-based material included in the amine-based CO2 adsorbent 121 can include high-density pores, and as a result, the amine-based CO2 adsorbent 121 has a high specific surface area. In some embodiments, the amine-based material included in the amine-based CO2 adsorbent 121 is selected such that CO2 adsorption occurs at ambient temperature and regeneration of the material during the desorption process occurs at 80 - 120 °C to release CO2.

[0019] The CO2 desorption device 130 is fluidly and / or thermally coupled to the CO2 adsorption chamber 120 and desorbs CO2 from the amine-based CO2 adsorbent 121. In some embodiments, the CO2 desorption device 130 desorbs CO2 from the amine-based CO2 adsorbent 121 by generating steam and directing the steam towards the amine-based CO2 adsorbent 121. In such embodiments, the steam is generated using electrical energy 113 generated by the wind turbine 110 and water, for example, from a water reservoir (not shown). In some embodiments, during the desorption process, the CO2 desorption device 130 is fluidly coupled to the CO2 adsorption chamber 120 for supplying steam onto the amine-based CO2 adsorbent 121. In some embodiments, the released CO2 is dissolved in the condensed steam (liquid water) formed on the surface of the amine-based CO2 adsorbent 121, and the CO2-containing liquid water is returned to the water reservoir. Alternatively or additionally, in some embodiments, the released gaseous CO2 is generated by the CO2 desorption device 130 and flushed into the water reservoir by the steam introduced into the CO2 adsorption chamber 120. In either case, during the desorption process, the CO2 disposed within the amine-based CO2 adsorbent 121 may be transferred to the water reservoir for subsequent separation and / or storage. Alternatively, in some embodiments, the CO2 desorption device 130 desorbs CO2 from the amine-based CO2 adsorbent 121 by directly heating the amine-based CO2 adsorbent 121 via, for example, a resistance heater (not shown) powered by electrical energy 113.

[0020] In some embodiments, the CO2 desorption device 130 and / or the CO2 adsorption chamber 120 is fluidly coupled to a device (not shown) for the isolation and / or storage of the CO2 107 removed from the ambient air 106 processed by the direct air carbon capture system 100. In some embodiments, the gaseous CO2 is captured by the direct air carbon capture system 100 and separated into carbon and oxygen. Alternatively or additionally, in some embodiments, the CO2-containing water is generated 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 (not shown) for the subsurface injection of the CO2-containing water, and the CO2 is permanently removed from the biosphere via an inorganicization process.

[0021] During operation, a portion of the ambient air 106 flowing across the blade 111 is received by the opening 104, which is fluidly coupled to the CO2 adsorption chamber 120 via one or more conduits 105. The opening 104 is disposed on one or more surfaces of each blade 111 such that the ambient air 106 incident on the opening 104 is received by the opening 104 and flows through the conduit 105 into the CO2 adsorption chamber 120. To that end, in some embodiments, the opening 104 is disposed at a specific portion of the surface of each blade 111 that causes such an air flow. Specifically, the specific portion of the surface may be a portion of the blade surface that is in fluid contact with the high-pressure region generated by the blade 111 when the ambient air 106 flows across the blade 111. Embodiments of the position of the opening 104 will be described below in conjunction with FIG. 2.

[0022] Figure 2 schematically shows a cross-section of blade 111 of wind turbine 110 according to various embodiments. Generally, wind turbine 110 is oriented in the direction of the flow of ambient air 106, and blade 111 is oriented at a particular blade angle such that ambient air 106 has a relative velocity 206 that provides a suitable angle of attack 201 for blade 111. Angle of attack 201 is the angle at which ambient air 106 approaches blade 111. Figure 2 also shows the resulting pressure distribution 220 on the surface of blade 111 when ambient air 106 flows over blade 111 at angle of attack 201, where high pressure is indicated by solid arrows and low pressure is indicated by dashed arrows.

[0023] According to various embodiments, opening 104 (shown in FIG. 1) is disposed on one or more surfaces that are in fluid communication with high pressure region 202 generated by blade 111 when ambient air 106 flows across blade 111 at angle of attack 201. In some embodiments, one or more openings 104 are disposed at a portion of leading edge 211 of blade 111, a portion of trailing edge 212 of blade 111, and / or any other surface of blade 111 that is in fluid communication with high pressure region 202.

[0024] Note that angle of attack 201 is a combination of the free stream velocity of ambient air 106 and the rotational velocity of blade 111. Since the blade tip (not shown) necessarily moves more per rotation than the blade root (not shown), the rotational velocity of the cross-section of blade 111 increases from the blade root to the blade tip. As a result, blade 111 is typically twisted from root to tip to allow for an optimal or near-optimal value for angle of attack 201, thereby improving lift generation along the length of blade 111. Thus, the cross-sectional view shown in FIG. 2 shows a cross-section of blade 111 at a single position between the blade root and the blade tip. Thus, the example of resulting pressure distribution 220 shown in FIG. 2 corresponds to that single location.

[0025] Since the relative speed between the ambient air 106 and the blade 111 is highest at or near the tip of the blade 111, in some embodiments, the opening 104 is disposed proximate to the tip of the blade 111. Further, in some embodiments, the conduit 105 within each blade 111 has a tapered 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.

[0026] CO2 Adsorption in Turbine Blades FIG. 3 is a conceptual diagram of an atmospheric carbon direct capture system 300 configured to implement one or more aspects of various embodiments. Similar to the atmospheric carbon direct capture system 100, the atmospheric carbon direct capture system 300 removes CO2 from the ambient air via an atmospheric carbon direct capture process that is powered using electrical energy 313 generated by a wind turbine 310. In some embodiments, the total negative greenhouse gas emissions of this process are increased by consuming little or no fan energy as part of the atmospheric carbon direct capture process. As shown, the atmospheric carbon direct capture system 300 includes a wind turbine 110 having one or more blades 311 and a generator 312. The generator 312 generates electrical energy 313 as ambient air 106 flows across the blades 311 and the blades 311 rotate. In the embodiment shown in FIG. 3, an amine-based CO2 adsorbent 321 and a CO2 desorption device 330 are disposed within each turbine blade 311.

[0027] The amine-based CO2 adsorbent 321 includes a porous amine-based material that corresponds to the amine-based material included in the amine-based CO2 adsorbent 121 of FIG. 1. Further, in the embodiment shown in FIG. 3, the amine-based CO2 adsorbent 321 forms at least a portion of the surface of one or more blades 311. For example, in some embodiments, the amine-based CO2 adsorbent 321 forms a portion of the wall of one or more blades 311.

[0028] The CO2 desorption device 330 desorbs CO2 from the amine-based CO2 adsorbent 321. In some embodiments, the CO2 desorption device 330 includes a steam source 331, a heating element 332, and / or a vacuum generating device 333. In some embodiments, the CO2 desorption device 330 is powered by the electrical energy 313 generated by the generator 312. In the embodiment shown in FIG. 3, at least one CO2 desorption device 330 is disposed within each blade 311. The steam source 331 generates steam and directs the steam over or into the amine-based CO2 adsorbent 321 as part of the desorption process. As a result, the steam heats the amine-based CO2 adsorbent 321 such that CO2 307 is released from the amine-based CO2 adsorbent 321. The released CO2 307 is then removed from the amine-based CO2 adsorbent 321, for example via the vacuum generating device 333. Alternatively or additionally, in some embodiments, as part of the desorption process, the amine-based CO2 adsorbent 321 is heated via the heating element 332. In such embodiments, the CO2 307 released from the amine-based CO2 adsorbent 321 is captured by the vacuum generating device 333. The vacuum generating device 333 may be a vacuum pump or other device that generates a negative pressure and captures CO2 307 when released from the amine-based CO2 adsorbent 321.

[0029] During operation, the direct air carbon capture system 300 removes CO2 307 from the ambient air 106 for storage or sequestration. Specifically, when the ambient air 106 passes over the surface of the blade 311 formed by the amine-based CO2 adsorbent 321, the CO2 is adsorbed by the amine-based CO2 adsorbent 321. The adsorbed CO2 is then desorbed from the amine-based CO2 adsorbent 321 (e.g., via the steam source 331 and / or the heating element 332) and removed from the blade 311 (e.g., via the vacuum generating device 333). Note that no fan energy is used to create a continuous flow of CO2-based ambient air across the amine-based CO2 adsorbent 321.

[0030] In some embodiments, the CO2 desorption device 330 includes a movable CO2 desorption device that can desorb CO2 from different portions of the amine-based CO2 adsorbent 321 when the movable CO2 desorption device is moved to different positions within the blade 311. One such embodiment will be described below in conjunction with FIG. 4.

[0031] FIG. 4 is a more detailed view of a movable CO2 desorption device 400 according to various embodiments. The movable CO2 desorption device 400 is disposed within a wind turbine blade 411 of a wind turbine and is disposed relative to a surface 431 of a wall 401 of the wind turbine blade. As shown, the wall 401 of the blade 411 includes or is formed from an amine-based CO2 adsorbent 321 that removes CO2 from ambient air flowing over the wind turbine blade 411. During operation, the actuator 409 moves the movable CO2 desorption device 400 along the surface 431 such that different portions of the wall 401 can undergo the desorption process. In the embodiment shown in FIG. 4, the movable CO2 desorption device 400 includes a steam source 331 and a vacuum generating device 333. As shown, the steam source 331 directs steam towards the surface 431 and / or into the amine-based CO2 adsorbent 321, and the vacuum generating device 333 captures the CO2 407 released from the amine-based CO2 adsorbent 321. The captured CO2 407 is collected via a conduit 405 fluidly coupled to the movable CO2 desorption device 400 for isolation or storage.

[0032] In some embodiments, the desorption process is performed periodically, such as during an idle time of the wind turbine, for example. In other embodiments, the desorption process is performed continuously. In such embodiments, the movable CO2 desorption device 400 can be continuously moved along the surface 431 to desorb CO2 from portions of the amine-based CO2 adsorbent 321 and capture the desorbed CO2.

[0033] In some embodiments, the CO2 desorption device 330 includes a fixed CO2 desorption device capable of desorbing CO2 from the amine-based CO2 adsorbent 321. Such an embodiment will be described below in conjunction with FIG. 5.

[0034] FIG. 5 is a more detailed view of a CO2 desorption device 500 according to various other embodiments. The CO2 desorption device 500 is disposed within the wall 501 of a wind turbine blade 511 that includes or is formed by an amine-based CO2 adsorbent 321. Specifically, the CO2 desorption device 500 includes one or more heating elements 502 and one or more conduits 505 disposed within the wall 501. In some embodiments, the one or more conduits 505 include capillaries or other small channels to enhance the capture of the desorbed CO2. In some embodiments, the conduit 505 is fluidly coupled to a vacuum generating device such as the vacuum generating device 333 of FIG. 3. Alternatively, in some embodiments, the vacuum generating device is fluidly coupled to the internal region 503, and the desorbed CO2 is transferred from the wind turbine blade 511 through the internal region 503 instead of through the conduit 505.

[0035] In some embodiments, the heating element 502 periodically performs a desorption process on the amine-based CO2 adsorbent 321 by heating the amine-based CO2 adsorbent 321 to a suitable desorption temperature. In some embodiments, the desorption temperature of CO2 associated with the amine-based CO2 adsorbent 321 is the temperature at which the adsorbed CO2 passes through an activation barrier or the binding energy that keeps the CO2 adsorbed on the surface of the amine-based CO2 adsorbent 321.

[0036] In summary, the various embodiments shown and provided herein describe a low-energy direct air carbon capture process technology that is powered using electrical energy generated by a wind turbine. Specifically, due to the relative velocity between the flow of ambient air and the surface of the wind turbine blade, the air incident on the openings formed on the surface flows into the CO2 desorption device without using a fan or consuming the energy of a fan. Further, the CO2 desorption device is powered by the electrical energy generated by the wind turbine.

[0037] Compared with the prior art, at least one technical advantage of the disclosed design is that the disclosed design enables direct air carbon capture without the need for an external energy source or a large centralized renewable energy source. Further, the disclosed design enables a direct air carbon capture process that does not rely on a huge amount of fan energy. Thus, the direct air carbon capture process can have a lower total energy consumption requirement and the greenhouse gas emissions can be net negative. These technical advantages provide one or more technical improvements over the prior art approaches.
