Claim 0:
1. A hybrid post-combustion carbon dioxide capture system for capturing carbon dioxide from a flue gas, comprising:
a compressor adapted to produce a compressed flue gas stream at a compression rate determined by external electricity demand;
a membrane-based carbon dioxide separation unit configured to receive a first portion of the compressed flue gas stream from the compressor; and
an aqueous-based carbon dioxide capture unit configured to receive a second portion of the compressed flue gas stream from the compressor whereby the compressed flue gas stream is processed in parallel by the membrane-based carbon dioxide separation unit and the aqueous-based carbon dioxide capture unit wherein the membrane-based carbon dioxide separation unit and the aqueous-based carbon dioxide capture unit are configured to operate without recycling any recovered carbon dioxide removed from the compressed flue gas stream to the compressor, the membrane-based carbon dioxide separation unit and the aqueous-based carbon dioxide capture unit.
