A carbon dioxide (CO) capture and utilization system captures COfrom flue gas and utilizes the same to enhance algae or cyanobacteria growth. The system generally comprises a COcapture unit and a utilization unit that is in fluid communication with the COcapture unit. The COcapture unit includes a membrane COabsorber that captures COfrom incoming flue gas to produce a CO-rich solvent. The utilization unit processes the CO-rich solvent to produce a product stream that includes COand NHin a predetermined CO:NHratio. The product stream is delivered to a cultivation subsystem of the utilization of the unit including one or more species of algae or cyanobacteria. A method for capturing and utilizing COis also provided herein.
