Potential for sequestration of carbon dioxide in South Africa carbon capture and storage in South Africa

Abstract

CSIR was commissioned by DME to compile a report on the potential for sequestration of carbon dioxide in South Africa in 2004. This report was the first attempt to obtain a picture of this potential. In the paper the main findings of the 2004 report are summarized. In the introduction the background for the study is presented as well as the main goals of the project. The sources and quantities as well as the composition of the carbon dioxide containing waste streams were compiled. The potential for biological, geological, chemical and marine storage was determined and it was found that the biological storage potential is limited, the chemical storage potential is largely unknown, the geological storage potential may be large, but further study is required. The marine storage potential is probably very large, but the environmental impact may be serious
