Title
(EN) DEVICE, SYSTEM, AND METHOD FOR PASSIVE COLLECTION OF ATMOSPHERIC CARBON DIOXIDE
(FR) DISPOSITIF, SYSTÈME, ET PROCÉDÉ DE COLLECTE PASSIVE DE DIOXYDE DE CARBONE ATMOSPHÉRIQUE
Abstract
(EN)
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.

L'invention concerne un dispositif de collecte passive de dioxyde de carbone atmosphérique. Le dispositif comprend une chambre de libération comprenant une ouverture et un système de régénération de sorbant. Le dispositif comprend également une structure de capture couplée à la chambre de libération, comprenant au moins un support pliable et une pluralité de carreaux espacés le long du support pliable. Chaque carreau comprend un matériau sorbant. La structure de capture est mobile entre une configuration de collecte et une configuration de libération. La configuration de collecte comprend la structure de capture s'étendant vers le haut à partir de la chambre de libération afin d'exposer la structure de capture à un flux d'air et de permettre au matériau sorbant de capturer le dioxyde de carbone atmosphérique. La configuration de libération comprend le support pliable qui est plié et la pluralité de tuiles est suffisamment enfermée à l'intérieur de la chambre de libération pour que le système de régénération de sorbant puisse fonctionner sur la pluralité de carreaux afin de libérer le dioxyde de carbone capturé à partir du matériau sorbant et de former un gaz enrichi.
