Carbon dioxide (CO2) sequestration has emerged as a crucial action to mitigate the unprecedented challenges of global warming on human society. Carbon mineralization, a process whereby CO2 reacts with mineral cations such as magnesium to form insoluble solids, is a safe way for sequestrating CO2. As one of the largest reservoirs of mineral cations, seawater contains a high content of magnesium, which provides a gigaton-scale capacity for CO2 sequestration. However, the slow combination of CO2 and water prevents sequestering CO2 in seawater far from cost-viable. Carbonic anhydrases (CAs) form a family of enzymes that are widely used by organisms in accelerating the reaction between CO2 and water. This project aims to investigate the feasibility of CAs for overcoming slow CO2 and water combination in seawater, and develop a CA-based approach for sustainable CO2 seawater sequestration. We will compare CA enzymes from various organisms for their activities in seawater and identify the one with the highest efficacy. Conditions that benefit the enzyme performance will also be determined to improve CO2 sequestration rates. Successful completion of this project will enable the exploitation of the largely untapped potential of seawater in sequestering CO2, which will make a significant contribution towards mitigating global warming.
