Claim 0:
1. A method for performing a CO2 sorption/desorption cycle, comprising:
exposing CO2 to a sorbent in a first sorbent environment to sorb CO2 and generate heat at a sorption temperature;
transferring at least a portion of the heat generated at the sorption temperature to water in one or more first heat exchanger volumes associated with the first sorbent environment to form steam at the sorption temperature;
compressing at least a portion of the steam to form pressurized steam;
passing at least a portion of the pressurized steam into one or more second heat exchanger volumes associated with a second sorbent environment;
condensing the at least a portion of the pressurized steam in the second heat exchanger volumes at a desorption temperature to form water and generate heat at the desorption temperature; and
transferring at least a portion of the heat generated at the desorption temperature to a sorbent in the second sorbent environment to desorb CO2.
