The Council for Geoscience is investigating South Africa’s potential for geothermal energy, one of the largest emerging renewable energy options in the world, to augment the country’s energy solutions and to reach the nation’s integrated resource plan target for renewable energy. Preliminary investigations indicate that the country does indeed host low-enthalpy geothermal potential. Thus, the Council for Geoscience is currently leading geothermal research in South Africa by generating a variety of geoscientific data, in order to assess the country’s geothermal potential. The current phase of the project involves collecting magnetotelluric (MT) data to map structural controls and potential reservoirs of hot groundwater near known hot springs. The electrical imaging of low-enthalpy geothermal targets primarily aims to locate deeper hot water aquifer zones representing reservoir systems, and to map the fluid pathways. Geothermal systems are generally composed of fault and fracture systems filled with geothermal fluids. These systems may have high concentrations of dissolved elements, resulting in conducting electrolytes. Geothermal systems generally exhibit higher conductivity values than the host rock, making them ideal targets for the MT method.
