1. An enhanced capture structure, comprising:
a sorbent structure comprising a first CO2 sorbent material, the sorbent structure further comprising a first surface and a second surface opposite the first surface; and
a plurality of barriers extending outward from the sorbent structure, each barrier of the plurality of barriers sized and positioned such that as an airflow passes along the sorbent structure and over the barrier 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, opposite the first side;
wherein the plurality of barriers comprises a first set of barriers extending outward from the first surface of the sorbent structure and a second set of barriers extending outward from the second surface of the sorbent structure, the first set of barriers staggered with respect to the second set of barriers such that the airflow creates a plurality of high pressure regions and a plurality of low pressure regions proximate the sorbent structure, where each high pressure region formed proximate one of the first surface and the second surface of the sorbent structure is opposite a low pressure region formed on the other of the first surface and the second surface of the sorbent structure, creating a pressure differential that promotes CO2 mass transfer into the first sorbent material via convection through the sorbent structure.
