The rise in global atmospheric temperature due to increase in the atmospheric carbon dioxide concentration needs to be tackled immediately before it reaches the point of no return. The application of innovative technologies based on the concepts of bioelectrochemical systems (BESs) can contribute in this direction by simultaneously sequestrating CO2 and producing value-added products in the process. Wastewater treatment with simultaneous bioenergy and biofuel recovery is also one of the added advantage of employing BESs for CO2 fixation. This review focuses on the potential of employing BES-based technologies like microbial carbon capture, plant-microbial fuel cell and microbial electrosynthesis cell for the concomitant production of valuables and CO2 sequestration. Also, various parameters affecting performance of BES that need to be optimized for the proper field-scale demonstration of these technologies are discussed.
