1. A carbon dioxide (CO2) liquefaction system, comprising:
a) a first pressure vessel having at least three ports in fluid communication with a corresponding conduit;
b) a second pressure vessel that is set to a temperature no greater than ambient temperatures and that is configured with one or more ports;
c) a source of CO2 which is condensable at ambient temperatures and which is deliverable to a first port of said first pressure vessel; and
d) a pump for delivering a liquid to a second port of said first pressure vessel,
wherein the CO2 is substantially isothermally compressible within said first pressure vessel upon direct contact with the delivered liquid,
wherein, following introduction of a sufficient additional volume of the liquid to said first pressure vessel, at least a portion of the compressed CO2 is transferable from said first pressure vessel through a third port of said first pressure vessel to said second pressure vessel upon direct contact with the liquid and is storable in a liquid state within said second pressure vessel after being compressed to its saturation pressure and condensed.
