Abstract
The negative impacts of global warming on climate have been witnessed worldwide, and therefore global efforts to decrease the emission of greenhouse gases (GHGs), particularly carbon dioxide, have increased. Carbon capture (CC) strategies can effectively reduce the quantity of CO2 being released into the atmosphere by various industries. In this study, several characteristics of CC technologies are analysed, the negative environmental impacts of CO2 emissions are highlighted, policies that have recently been adopted to decrease GHG emissions are discussed, and state-of-the-art post-combustion CC, pre-combustion CC, and oxyfuel combustion CC technologies are reviewed. Furthermore, this study investigates and compares the three most common carbon separation techniques, namely, absorption, adsorption, and membrane methods. Through the investigation of the CC technologies, we discuss the practicality of implementing such methods and discuss specific case studies that have implemented CC technologies. Furthermore, we summarise ways of utilising the end-product (the captured carbon) of these technologies. Much research has gone into investigating the negative environmental impacts that are currently arising. This paper stresses the importance of taken measures that go from theory to implementation and how such measures can be approached.
