Recently, after the discovery of gas in Mozambique, the country boosted its energy mix to include more gas, which emits less carbon dioxide than coal power plants.
The Karoo shale basin is considered a good prospect of shale gas due to the presence of mature black shales, the report explains.
“Eskom officials also estimate that shale gas from the Karoo could be produced and directly absorbed by existing electricity networks up to 1 to 2 GW, with no need for pipelines, which enables progress even in the low price environment,” it said.
