Eskom’s coal technology roadmap will try to determine whether and when we can expect viable clean-coal technologies such as the integrated gasification combined cycle, underground gasification combined cycle, oxy-fuel combustion and carbon capture and storage as well as super critical boilers which operates with exceptional efficiency.

Eskom has modelled the potential contribution¹ of demand- and supply-side initiatives to the future reduction of CO₂ emissions. The possible scenarios are illustrated in the figure below:

The first graph indicates a baseline (200Mt line) with a high percentage of coal in the mix (88%). The plotted lines indicate the potential contribution of emission reduction by various technologies. The four corresponding pie-charts depict the projected annual emission reduction, which could be achieved through this particular diversification strategy.

As indicated in the graphs², Eskom’s overall CO₂ emissions will increase over the medium term but the pace of increase will be reduced with the diversification of our mix. The introduction of additional nuclear plants will be the main contributor.
