Described herein are methods and devices for selective membrane-driven gas transfer.

A process for capturing greenhouse gas emissions utilizing algae may comprise feeding a carbon dioxide feed stream, a recycle water stream, and light to a closed photobioreactor, thereby forming oxygen and the algae; extracting the oxygen and at least a portion of the algae from the closed photobioreactor, the algae extracted as a wet biomass stream; introducing the wet biomass stream to a dewatering unit along with an exhaust gas stream comprising carbon dioxide, thereby forming steam, a reduced temperature exhaust gas stream, and a dehydrated biomass product; introducing at least a portion of the steam to a cooling unit, thereby condensing the steam and forming the recycle water stream; and introducing the reduced temperature exhaust gas stream to a treatment unit, thereby forming the carbon dioxide feed stream.
