Improving CO2 Capture Using Deep Eutectic Solvents

Both natural gas production and fossil fuels production are the main sources to most of the energy consumption, this gas presented a series of impurities, i.e. CO2, which needed to be eliminated in order to prevent several concerns as the corrosion of equipment, greenhouse gas emissions and others. It is thus clear, that the development of efficient CO2 capture and storage processes are important to reduce both CO2 production and its contribution to global warming. From gaseous streams CO2 can be captured by three technologies: absorption, adsorption and membranes, however, they have some challenges in its utilization to be resolved, and some groups of scientists try to resolve it by the inclusion of deep eutectic solvents in them. In the present work, the most recent developments (2024 year) in CO2 capture using deep eutectic solvents (DESs) jointly to absorption, adsorption or membrane-based technologies have been reviewed.
