1. A dual-cell cross flow gas contactor for capturing atmospheric CO2, the dual-cell cross flow gas contactor comprising:
an induced fan within a fan cowling, the induced fan coupled to a structural housing;
one or more sections of drift eliminator material comprising outer edges, the outer edges sealed to the structural housing to fill gaps between the one or more sections of drift eliminator and the structural housing;
one or more sections of packing material coupled to the structural housing and having an air travel depth between 4 meters and 9 meters defined between a packing inlet and a packing outlet, the one or more sections of packing material including a first section and a second section spaced apart from the first section, the one or more sections of packing material configured to be wetted by a process solution having a CO2-absorbing capacity;
an open plenum section within the structural housing and defined between the packing outlet of the one or more sections of packing material and the fan cowling;
a basin configured to collect the process solution from the one or more sections of packing material; and
piping fluidly coupling the basin to the one or more sections of packing material, the piping configured to redistribute at least a portion of the process solution collected in the basin from the one or more sections of packing material directly back to the one or more sections of packing material.
