CO₂ has been used for many decades in the industrial processes and food manufacturing, including soft drinks. Likewise, it is an essential component of other everyday items such as fire extinguishers. In very high concentrations, CO₂ like any dense gas, can act as an asphyxiate material, which can be dangerous to humans with its adverse impact on respiration. Thus, CO₂ is captured to minimize risks to humans’ health and the environment. A general overview of the current carbon capture and storage (CCS) and CO₂ based enhanced oil recovery (CO₂-EOR) projects is presented in this paper. This work provides a summary of the current worldwide CCS and CO₂-EOR projects along with their potential benefits. CCS is a process used to capture CO₂ that is produced by industrial facilities. The CCS technology involves CO₂ capture, transport, and storage. On the other hand, EOR is a generic term for various techniques to increase recovery from oil fields. The injection of CO₂ into underground rock formation of oil reservoirs in order to improve their recovery is called CO₂-EOR.
