<p>Currently, energy needs still rely on fossil fuels. On the other hand, CO<sub>2</sub> emissions resulting from burning fossil fuels continue to increase and contribute as a greenhouse gas in the atmosphere. Global warming is a threat to the future of life. One of the countermeasures is by developing Carbon, Capture, and Utilization (CCU) technology based on a chemical absorption process to capture CO<sub>2</sub> gas from combustion. The captured CO<sub>2</sub> is then stored in a stable form so it will not be released into the atmosphere or used as raw material for the chemical industry. The main obstacle to implementing CCU technology on a large scale is the cost involved. Meanwhile, the revenue generated is relatively low. In CCU technology based on this chemical absorption process, chemicals as absorbents need to be regenerated and the CO<sub>2</sub> is separated for storage or use. However, this regeneration requires a relatively high cost. Several studies have attempted to perform this regeneration with micro-algae-based bioprocesses. Micro-algae can take energy from sunlight which is abundant in tropical areas such as Indonesia. In addition, several types of micro algae have the potential to be used as food and other utilizations. This review will discuss the results of recent research on suitable chemicals for the absorption of CO<sub>2</sub> from flue gas, its regeneration method using micro-algae, usable micro-algae species, and the potential for micro-algae utilization.</p>
