Abstract: A system for producing gas streams for use in synthetic fuel production through CO2 capture and water splitting is disclosed. The system includes a CO2 capture device configured to receive a CO2-containing stream and including an aqueous alkaline solution. The alkaline solution includes hydroxide and/or carbonate ions. The CO2 capture device generates a carbon-rich solution when the alkaline solution absorbs CO2. The carbon-rich solution includes carbonate and/or bicarbonate ions. The system also includes an electrolyzer fluidically coupled to the CO2 capture device, and defining a volume including an anode region having an anode, and a cathode region having a cathode. The volume includes an electrolyte solution having a pH gradient generated by an electric current, causing the electrolyte solution to be acidic in the anode region and alkaline in the cathode region. The carbon-rich solution is received into the electrolyzer. The electrolyzer generates hydrogen, oxygen, and CO2 streams.

Abstract: A device for passive collection of atmospheric carbon dioxide is disclosed. The device includes a release chamber having an opening and a sorbent regeneration system. The device also includes a capture structure coupled to the release chamber, having at least one collapsible support and a plurality of tiles spaced along the collapsible support. Each tile has a sorbent material. The capture structure is movable between a collection configuration and a release configuration. The collection configuration includes the capture structure extending upward from the release chamber to expose the capture structure to an airflow and allow the sorbent material to capture atmospheric carbon dioxide. The release configuration includes the collapsible support being collapsed and the plurality of tiles being sufficiently enclosed inside the release chamber that the sorbent regeneration system may operate on the plurality of tiles to release captured carbon dioxide from the sorbent material and form an enriched gas.

Abstract: A system for collecting a sorbate gas from a sorbent is disclosed, including a regeneration vessel enclosing a sorbent having a sorbate gas, a liquid water supply heated to a first temperature, and a heat pump with a condenser. The heat pump is also in contact with the water supply. Heat is removed from the condenser and used to heat the water supply to the first temperature. The system includes a compressor coupled to the condenser. The sorbent within the vessel is placed in contact with water vapor at the first temperature. The water vapor coming into contact with the sorbent causes sorbate gas to be released, forming a mixture including sorbate and water gases, raising the pressure. The vapor mixture is removed and cooled by the condenser, where a portion is condensed into water that is returned to the supply. The remaining mixture is compressed into a product gas.

Abstract: A passive CO2 collection device is disclosed, including a release chamber and a capture structure having at least three straps and a plurality of sorbent disks coupled to and spaced along the straps. The capture structure is movable between collection and release configurations. Each strap has a primary and secondary width, the secondary width smaller than the primary. The collection configuration includes the disks suspended from a movable portion by the straps such that, for each pair of neighboring disks and for each strap, a lower disk is separated from an upper disk by a connecting segment, allowing the sorbent to capture carbon dioxide from an airflow. The release configuration includes the disks being stacked within the chamber for regeneration. Each connecting segment is in a release topology designed to accommodate stacking the disks within the chamber. The connecting segment is biased to move toward the release topology.

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 method for enhancing a sorbent membrane for carbon dioxide capture is disclosed. The method includes applying a layer of a hydrophobic material to at least one surface of the sorbent membrane. The hydrophobic material may be one of a polysioxane, a silicone compound, and a fluoroacrylic copolymer. The sorbent membrane may be an anionic exchange membrane, and may have a quaternary ammonium functional group. The layer of hydrophobic material reduces the amount of water used in the carbon dioxide capture process, and relaxes the water quality constraints.

Abstract: Embodiments of the invention a method for producing a composite paper by providing a particulate sorbent, providing a paper pulp, and mixing the particulate sorbent and the paper pulp to develop a mixture. The method includes producing an article from the mixture that includes the particulate sorbent at least partially distributed through at least a portion of the article. Further, the at least one article is configured and arranged to uptake and release carbon dioxide as a function of moisture content. Some embodiments of the invention include a composite paper-like assembly including at least a first and second layer including hydrophobic fibers, and sorbent particles and/or a sorbent loaded paper sandwiched between the first and second porous sheets. Some further embodiments include a method for producing a material that supports a moisture swing by providing a material including activated carbon, and infusing the activated carbon with ionic salt.
