Abstract: Disclosed herein is a system comprising an absorber; the absorber being operative to extract carbon dioxide from a flue gas stream to form a carbon capture solution that is rich in carbon dioxide; and an electrolytic cell disposed downstream of the absorber; where the electrolytic cell is operative to reduce carbon dioxide present in the carbon capture solution. Disclosed herein too is a method comprising discharging a flue gas stream from a flue gas generator to an absorber; contacting the flue gas stream with a carbon capture solution; extracting carbon dioxide from the flue gas stream to form a carbon dioxide rich carbon capture solution; discharging the carbon dioxide rich carbon capture solution to an electrolytic cell; and reducing the carbon dioxide to a hydrocarbon in the electrolytic cell.
