South Africa has started geological mapping at the country’s first carbon capture and storage (CCS) site, where it plans to inject vast quantities of carbon dioxide (CO2) deep underground from 2023, a senior Council for Geoscience official said. The project will be based around the town of Leandra, Mpumalanga province, in South Africa’s north east, a carbon emissions hotspot and home to several coal-fired power stations as well as Sasol’s Secunda coal-to-liquids fuel plant, the world’s largest.
