Abstract
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 CO2 from 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 CO2 collected by the capture structure to form an enriched fluid.
