Carbon capture and utilization (CCU) technology represents a viable process to mitigate the rising carbon emissions. Enzymatic CCU technology has gained recent attention due to its possibility to convert waste CO2 as a by-product of postcombustion carbon capture into value-added materials. Compared to the conventional amine-based carbon capture technology, enzymatic carbon capture allows for the utilization of greener solvents that is beneficial to the environment. The absence of amine-based absorbents has a potential to reduce the energy requirement for solvent regeneration. Furthermore, the role of enzymes as biocatalysts can enhance the CO2 absorption kinetics, which has an impact on reducing the equipment footprint. This chapter reviews different in vitro enzymatic reactions proposed for CCU applications followed by their immobilization on the support. Finally, the integration of these enzymes into conventional absorption column and membrane technology was elaborated. In this chapter, the current challenges of applying enzymes as a feasible and practical carbon capture technology are discussed.
