1. A carbon capture system, comprising:
a plurality of thermal swing adsorption (TSA) beds for CO2 capture, including at least:
a first TSA bed configured to capture CO2 within a capture temperature range and to regenerate captured CO2 at a regeneration temperature range above the capture temperature range;
a second TSA bed configured to capture CO2 within the capture temperature range and to regenerate captured CO2 at the regeneration temperature range; and
a third TSA bed configured to capture CO2 within the capture temperature range and to regenerate captured CO2 at the regeneration temperature range;
a plurality of valves and associated flow paths configured to allow switching operational modes of each of the first TSA bed, the second TSA bed, and the third TSA bed; and
a dehydration subsystem to remove water from a portion of an engine exhaust flow, the dehydration subsystem including:
a plurality of first dehydration TSA beds upstream of and separate from the plurality of TSA beds; or
a plurality of second dehydration TSA beds that are physically integrated with the respective first, second, and third TSA beds.
