Abstract: In this study, we investigated the use of functionalized deep eutectic solvents (DESs) as a medium for CO 2 capture integrated with CO 2 desorption and biofixation in microalgal culture, as an approach for carbon capture, utilization, and storage (CCUS). The newly devised DES formulation—comprising choline chloride, ethylene glycol, and monoethanolamine—demonstrated a significant advancement in CO 2 absorption capacity compared with conventional solvents. Effective CO 2 desorption from the solvent was also achieved, recovering nearly 90% of the captured CO 2 . We then examined the application of the functionalized DESs to promote microalgal cultivation using a Chlorella sp. strain. The experimental results indicated that microalgae exposed to DES-desorbed CO 2 exhibited heightened growth rates and enhanced biomass production, signifying the potential of DES-driven CO 2 capture for sustainable microalgal biomass cultivation. This research contributes to the growing field of CCUS strategies, offering an avenue for efficient CO 2 capture and conversion into valuable biomasses, thereby contributing to both environmental sustainability and bioresource use.
