Abstract
A carbon dioxide (CO2) capture and utilization system captures CO2 from flue gas and utilizes the same to enhance algae or cyanobacteria growth. The system generally comprises a CO2 capture unit and a utilization unit that is in fluid communication with the CO2 capture unit. The CO2 capture unit includes a membrane CO2 absorber that captures CO2 from incoming flue gas to produce a CO2-rich solvent. The utilization unit processes the CO2-rich solvent to produce a product stream that includes CO2 and NH3 in a predetermined CO2:NH3 ratio. 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 CO2 is also provided herein.
