Abstract
Methods and apparatus for capturing carbon dioxide from ambient air and delivering said carbon dioxide to an enclosed environment are described. In general, the methods and apparatus comprise contacting a packed bed or fluidized bed device with a stream of ambient air, wherein the packed bed or fluidized bed device comprises a humidity-sensitive sorbent material that adsorbs carbon dioxide from the ambient air; contacting the packed bed or fluidized bed device with a stream of humid air to release the adsorbed carbon dioxide; delivering the released carbon dioxide to an enclosed environment; and optionally, repeating the steps of contacting the packed bed or fluidized bed device with ambient air and humid air in an alternating fashion.
