As we continue to review the Geothermal opportunities across Africa, many people would be familiar with the high enthalpy geothermal resources being developed in EARS. Kenya is one of the world leaders here producing clean electricity. Other countries along the rift system have begun developing Geothermal Energy, but many more […]

Cameroon is another African country with energy challenges. There are conventional onshore and offshore oil and gas developments, but there is a need for more electrification to support people’s living standards, education, clean water and improved sanitation, and the economy. There are good Geothermal Energy opportunities across the country and […]
Ghana is our next African country to highlight Geothermal Energy opportunities. Blessed with valuable mineral ores and offshore oil & gas, Ghana also has clean, environmentally sustainable Geothermal Energy prospects. A resilient energy grid needs more baseload and Geothermal is persistent and dispatchable. Funding and finance is available for renewable […]
Namibia is the next African country to highlight the Geothermal Energy potential. The Damara Orogenic belt is the home to good geological conditions with hot spring surface manifestations of subsurface hydrothermal reservoirs. Clean, persistent renewable Geothermal Energy able to attract good funding and finance is an economic, environmentally sustainable solution […]
South Africa has many mineral resources and some offshore hydrocarbon resources, but beneath the ground in a number of locations is clean, persistent renewable resource Geothermal Energy. Solar PV and Wind energy is good but intermittent, so either significant Energy Storage Systems are required or else some source of baseload […]
Significant Opportunities Continuing a series of posts about increased energy opportunities in African countries, here is a short flyer about Geothermal in Zimbabwe. Resilient energy systems should be a mix of renewables and baseload, and Geothermal is both – clean, persistent, environmentally sustainable.African Energy Chamber ‘s #aew2021 in Cape Town […]
Nigeria is a country blessed with significant conventional oil and gas resources, but there is a significant source of clean, persistent renewable energy beneath the surface also – Geothermal Energy. With good geoscience and well data, there may be an opportunity to repurpose some end of life oil and gas […]
For those more familiar with conventional oil & gas resources, it is convenient to make a comparison showing similarities and differences: Oil & Gas Geothermal Energy Source Rock – fine-grained sediments with sufficient amounts of organic matter, which generate and release hydrocarbons able to migrate upwards;Fluids – hydrocarbon oil & […]
Another well known source of Geothermal Energy is at Divergent Zones of tectonic plates (e.g., East African Rift) or at Hot Spots (e.g. Hawaii). Once again both hydrothermal and petrothermal reservoirs are able to be exploited with production and injection wells to produce clean, persistent Geothermal Energy. Volatile fluid release […]
Africa is fortunate to have significant clean Gas resources, but not all countries have them. With the challenges of electrification and elimination of energy poverty, there is a persistent, environmentally sustainable renewable available to provide this energy. Geothermal is a natural pivot for traditional upstream companies to broaden their asset […]
Another potential location for accessing Geothermal Energy is Subduction Zones associated with Volcanic Arc Geology. Hydrothermal and/or petrothermal reservoirs are possible to be exploited for significant enthalpy with production and injection wells. Volatile fluid release from subducted crust includes carbon components from organic matter, carbonates, water and hydrous materials. These […]
Geothermal energy is able to be captured from several types of subsurface locations. One such location is Hydrothermal Reservoirs which may have been found during conventional oil & gas exploration and development. These heated aquifers are able to be utilised by repurposing some wells and/or drilling new wells for fluid […]
