A carbon dioxide collection system having a release enclosure, a capture structure, and a chimney is disclosed. The release enclosure includes a sorbent regeneration system. The capture structure includes a sorbent material, and is movable between collection and release configurations. The chimney is shaped such that an airflow upward through the chimney is created. The chimney is positioned above the release enclosure such that the airflow passes through the capture structure while in the collection configuration. The collection configuration includes the capture structure being elevated above the release enclosure so the sorbent material is exposed to the airflow generated by the chimney, allowing the sorbent material to capture COfrom the airflow. The release configuration includes the capture structure being sufficiently enclosed inside the release enclosure that the sorbent regeneration system may operate on the sorbent material to release COcollected by the capture structure to form an enriched fluid.

System and method for passive collection of atmospheric carbon dioxide with enhanced air flow

A device for passive collection of atmospheric carbon dioxide is disclosed, including a vessel having an opening and a sorbent regeneration system. The device also includes a helical sorbent structure rotatably coupled to the vessel. The sorbent structure has a helical framework coupled to a sorbent material. The sorbent structure is movable between collection and release configurations. The collection configuration includes the sorbent structure extending upward from the vessel to expose the sorbent structure to an airflow and allow the sorbent material to capture atmospheric CO. The sorbent structure is free to rotate on an axis. The sorbent material is constrained to a helix rotating about and propagating along the axis. The release configuration includes a lid covering the opening, and the sorbent material being sufficiently enclosed inside the vessel that the regeneration system may operate to release captured COfrom the sorbent material and form an enriched gas.

Passive COcapture device with a helical sorbent structure

A system and method for passive collection of atmospheric carbon dioxide is disclosed. The system includes a harvest chamber having a first opening and a sorbent regeneration system. The system also includes a capture body coupled to and movable by a support structure. The capture body includes a sorbent material and is movable by the support structure to be in a collection configuration wherein at least a portion of the capture body is in contact with a natural airflow outside the harvest chamber such that atmospheric carbon dioxide is captured by the sorbent material, and a release configuration wherein at least a portion of the capture body holding captured carbon dioxide is operated upon by the regeneration system inside the harvest chamber such that captured carbon dioxide is released to form an enriched gas.

System and method for passive collection of atmospheric carbon dioxide

A system for capturing atmospheric carbon dioxide is disclosed, including a track and a plurality of panels moveably coupled to the track, each panel having a sorbent material. The system also includes a harvest house having a sorbent regeneration system and at least one aperture, and a propulsion system coupled to the track and configured to move each panel in a circuit having a collection phase and a release phase. For each panel, the collection phase of the circuit includes the panel moving along the track to expose the sorbent material to an airflow and allow the sorbent material to capture carbon dioxide. For each panel, the release phase of the circuit includes the panel being sufficiently enclosed inside the harvest house that the sorbent regeneration system may operate on the sorbent material to release captured carbon dioxide from the sorbent material and form an enriched gas.

Moving sorbent panel system for capturing atmospheric carbon dioxide

An enhanced capture structure is disclosed, including a sorbent structure having a COsorbent material. The capture structure also includes a plurality of barriers extending outward from the sorbent structure, each sized and positioned such that as an airflow passes along the sorbent structure, a high pressure region forms proximate the sorbent structure on a first side of the barrier facing into the airflow and a low pressure region forms proximate the sorbent structure on a second side of the barrier facing away from the airflow. The barriers on one side of the sorbent structure are staggered with respect to barriers on the other side such that a plurality of high and low pressure regions are formed, each high pressure region being formed opposite a low pressure region on the other side of the structure, creating a pressure differential that promotes COmass transfer into the sorbent material via convection.

Enhanced capture structures for direct air capture

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.
