However, in South Africa, it is all talk and has been all talk for the past 20 years," he said.."We don't even have a gas masterplan and don't have significant quantities of indigenous natural gas. The finds we do have off the Southern Coast have proven to be technically and commercially difficult, resulting in companies like Total Energies walking away.".Read also:.🔒 The energy transition is powered by — wait for it — coal: Javier BlasSouth Africa enacts law to end Eskom's monopoly and boost electricity market competitionRational perspective: Why SA must embrace nuclear, coal to power growth.This article was first published by MyBroadband and is republished with permission.
