Abstract

Disclosed herein are systems and methods for reducing power plant CO2 emissions. In one embodiment, a method for reducing emissions in a combustion stream, comprises: combusting a gaseous stream to produce an exhaust stream comprising carbon dioxide, and separating CO2 from the exhaust stream by passing CO2 through a membrane to produce a CO2 product stream and a CO2 lean exhaust stream.
