Abstract: A device and method for carbon dioxide capture using circumscribed hollow membranes is disclosed. The device includes a hollow membrane unit having an inner conduit composed of a vapor membrane, and an outer conduit having an inside surface circumscribing the inner conduit forming a lumen. The outer conduit includes a CO2 pump membrane. The device also includes a mechanical pump maintaining a pressure differential between the lumen and the atmosphere, providing a product stream of CO2-rich gas from the lumen. The vapor membrane is sufficiently hydrophobic and porous to contain liquid water while also allowing water vapor formed by evaporation to pass through into the lumen. As water vapor passes from the lumen to the atmosphere through the CO2 pump membrane, a carbon concentration gradient is formed and maintained across the CO2 pump membrane. The carbon concentration gradient actively pumps CO2 out of the atmosphere and into the lumen.

Abstract: A carbon dioxide capture and release method of forming a MOF matrix material including at least one metal-organic-framework crystal that includes at least one metal ion or metal ion cluster coordinated to polydentate organic ligands. The method includes forming a positive moisture swing CO2 host by application of at least a portion of the MOF matrix material to at least a portion of a good, and exposing the good to a feed gas. The method also includes altering the absorption and desorption of CO2 in the CO2 host through a swing absorption/desorption process of moisture content, where an equilibrium pressure of CO2 over the CO2 host is based at least in part on the moisture content. The metal-organic-framework crystal can be UIO-66 including Zr6O4(OH)4(CO2)12 clusters linked by terephthalate acid ligands, and/or Zr6O4(OH)4(CO2)12 clusters linked by amino-terephthalic acid ligands, and/or Zr6O4(OH)4(CO2)12 clusters linked by nitro-terephthalic acid ligands.

Abstract: A device, method, and system for CO2 capture is disclosed. The method includes receiving a process vapor including water and CO2 into a vessel at an intake pressure, the vessel having a desiccant and a CO2 sorbent material. The method includes passing the process vapor through the desiccant and sorbent, the desiccant absorbing the water resulting in a dry vapor, the sorbent absorbing CO2 from the dry vapor resulting in a CO2-lean dry vapor. The method includes discontinuing the process vapor, desorbing the water from the desiccant by at least one of reducing pressure downstream from the desiccant to below the intake pressure and increasing a temperature of the desiccant, desorbing the CO2 from the sorbent by placing the desorbed water in contact with the sorbent, removing the desorbed CO2 through the product outlet as a product stream, and desorbing a remaining water from the desiccant and the sorbent.

Abstract: A continuous CO2 capture system, method, and device are disclosed. The device includes a CO2 pump membrane including a moisture-swing material, and a cavity having a first fluid. The CO2 pump membrane separates the first fluid from a second fluid, the fluids creating a water concentration gradient across the membrane and transport of water through the membrane. The water concentration gradient creates a carbon concentration gradient across the membrane that decreases moving from outside the cavity to inside the cavity. As water is continuously transported from the first fluid to the second fluid through the CO2 pump membrane because of the water concentration gradient, carbon dioxide is continuously captured from the second fluid by the moisture-swing material of the CO2 pump membrane and continuously pumped along the carbon concentration gradient across the CO2 pump membrane and into the first fluid within the cavity.

Abstract: A system, device, and method for passive collection of atmospheric carbon dioxide is disclosed. The device includes a release chamber having a sorbent regeneration system with a power supply, and a capture structure coupled to the release chamber, having a plurality of disks coupled to and spaced along at least one collapsible support. Each disk has an electro-swing sorbent material. The capture structure is movable between collection and release configurations. The collection configuration includes the capture structure extending upward to expose the structure to an airflow and allow the sorbent to capture atmospheric carbon dioxide while a collection voltage is established across the sorbent material. The release configuration includes the disks enclosed inside the release chamber and conductively coupled to the power supply such that a release voltage is established across the electro-swing sorbent material, resulting in the release of captured carbon dioxide forming an enriched gas.

Abstract: An autothermal direct air capture system (ADAC) is disclosed. The ADAC includes a chamber, a water reservoir, and a sorbent that releases water under ambient conditions, binds water under a first moisture level higher than the ambient moisture level, binds CO2 under ambient conditions, and releases CO2 under at least one of an elevated temperature and the first moisture level. The ADAC is movable between a capture configuration and a regeneration configuration, the capture configuration including the sorbent being exposed to a gas volume having CO2 under ambient conditions, the sorbent binding with CO2 while desorbing water, the sorbent selected so the sorbent material extracts heat while the ADAC is in the capture configuration, resulting in the thermal charging of the sorbent. The regeneration configuration includes the sorbent inside the chamber and in contact with water, the sorbent releasing carbon dioxide while binding water and depositing heat into the chamber.

Abstract: A system for water rejuvenation for the regeneration of sorbent filters is disclosed. The system includes an anion reduction subsystem having a plurality of anionic exchange resin beds configured to remove impurity anions from a wash water used in a moisture-swing, direct-air-capture device. Each resin beds is in a vessel inside of which is configured to perform at least one of three operations: (1) conditioning resin beds by flushing them with carbonate or bicarbonate, (2) upgrading the wash water by removing impurity anions from the wash water reservoir, and (3) cleaning input water by exchanging impurity anions for carbonate or bicarbonate ions in the input feed.

The system also includes a cation reduction subsystem that reduces the salinity of the wash water, and a divalent reduction subsystem that softens the wash water by removing divalent ions.
