The Potential of CO2 Capture and Storage Technology in South Africa?s Coal-Fired Thermal Power Plants

Resumen

The global atmospheric concentration of anthropogenic gases, such as carbon dioxide, has increased substantially over the past few decades due to the high level of industrialization and urbanization that is occurring in developing countries, like South Africa. This has escalated the challenges of global warming. In South Africa, carbon capture and storage (CCS) from coal-fired power plants is attracting increasing attention as an alternative approach towards the mitigation of carbon dioxide emission. Therefore, innovative strategies and process optimization of CCS systems is essential in order to improve the process efficiency of this technology in South Africa. This review assesses the potential of CCS as an alternative approach to reducing the amount CO₂ emitted from the South African coal-fired power plants. It examines the various CCS processes that could be used for capturing the emitted CO₂. Finally, it proposes the use of new adsorbents that could be incorporated towards the improvement of CCS technology.
