South African Centre for Carbon Capture & Storage


Pilot Monitoring Project.

Natural occurrences of Carbon Dioxide releases within the subsurface are common around the world, especially in environments where carbonate rocks are in contact with groundwater that allows for dissolution, releasing natural Carbon Dioxide. However, the natural Carbon Dioxide gas releases in the South of Harding and along the Umtamvuna River on the border between KwaZulu-Natal and Eastern Cape Provinces, are unique within South Africa. The Pilot Carbon Dioxide Monitoring Capacity Building Project (PMP) represent ideal sites for monitoring and modelling of natural Carbon Dioxide releases. The Carbon Dioxide releases were mapped by Du Toit between 1911 and 1916, but were first documented by Young (1924) who observed dry gas releases (98% Carbon Dioxide) on three farms ~17km southeast of Harding. 

The PMP is a SANEDI/SACCCS capacity building initiative that forms an integral component of the Pilot Carbon Dioxide Storage Project (PCSP). The potential sites are located at Harding in the KwaZulu-Natal and Bizana in the Eastern Cape Provinces along the +80km long geological fault.    

The PMP aims to build carbon dioxide monitoring capacity and skills transfer to the interested and affected parties, namely:

  • Ugu District Municipality
  • Alfred Nzo District Minicipality;
  • Umuziwabatu Local Municipality;
  • Mbizana Local Municipality;
  • Mthimude Tribal Court;
  • Izibonda Tribal Court; and
  • Kwa-Jali Tribal Court.
