Dr Ranajit Sahu, an engineer with more than three decades of experience in power plant design, has found that large quantities of greenhouse-gas (GHG) emissions are “unavoidable”, even if the cleanest available technology is used for new coal-fired power generation. South Africa’s Integrated Resource Plan for Electricity (IRP) 2019 claims that new coal generation capacity will be cleaner because high-efficiency, low-emission (HELE) generation technology will be used, although it does not state which kind.
