- Rwanda is contemplating agro-processes to reinforce its geothermal sources base.
- Africa’s geothermal investments are projected to succeed in $35 billion by 2050.
- By 2050, geothermal energy capability in Africa will greater than double Europe’s capability.
Rwanda geothermal vitality presents the East African nation a strategy to diversify its sources of electrical energy and cut back reliance on imported vitality. In response to official reviews, Rwanda is aiming so as to add 30 megawatts of geothermal energy to its electrical energy grid however additionally it is contemplating different makes use of of the vitality useful resource, owing to the prices associated to electrical energy era utilizing geothermal sources.
“We’re specializing in creating direct warmth utilization and persevering with exploration for deeper sources to supply electrical energy sooner or later,” Eugene Karangwa, Head of Different Energies and Geothermal at Rwanda Vitality Group (REG), introduced just lately. He mentioned Rwanda is trying to make the most of its geothermal sources straight for heating and drying, and never simply electrical energy era.
The Rwandan official added that the nation is collaborating with the United Nations, the UN Setting Programme for capability constructing on the right way to finest use their geothermal sources.
Because of the associated prices, and the character of our geothermal sources, the official mentioned, Rwanda is contemplating a number of purposes of the useful resource. Amongst different choices that the nation is exploring embody, agro-food processing, small-scale fisheries, vegetable drying, chilly storage, and different industrial processes that require warmth.
He defined that temperatures round 100 levels Celsius or decrease can be utilized for purposes akin to milk pasteurization, crop drying, and chilly storage to stop post-harvest losses and all these are choices we’re , he informed media.
“One drawback we’re addressing is the drying of rice to keep up its high quality from farm to manufacturing facility. There are additionally points with preserving vegetables and fruit, which may benefit from geothermal warmth,” famous Karangwa.

Challenges to Rwanda geothermal exploration plan
In response to the Head of Different Energies and Geothermal at Rwanda Vitality Group (REG), the most important problem slowing down their improvement of geothermal is the pricey nature of the exploration, specifically, the price of drilling wells.
“We are attempting to safe funding to drill deeper and develop a pilot venture combining geothermal with photo voltaic vitality for a chilly storage system,” Karangwa informed native media.
The federal government has to this point contributed over $200,000, which is about 20 per cent of the entire $800,000 required within the exploration of the Gisenyi geothermal prospect.
“REG can also be collaborating with European and Kenyan universities beneath the African Union and European Union Renewable Vitality framework beneath which Rwanda was chosen as a pilot website for the Geothermal Village idea,” the official informed press.
The official additionally revealed that Rwanda is tapping into grants to finance its geothermal ambitions and trying to have interaction inexperienced vitality companions to ascertain what he described as ‘a risk-sharing mechanism.’
“Which means that to draw non-public funding, a fund might be arrange the place a non-public firm drills wells, and if the wells are unsuccessful, a portion of the fee can be coated by the fund, lowering the chance for the non-public sector,” he defined.
On this regard, Rwanda is at the moment in talks with the Geothermal Threat Mitigation Facility (GRMF), he mentioned and in the identical vein, Rwanda is leveraging know-how for exploration actions, the official mentioned.
“If we use the newest applied sciences, we can conduct deeper analysis geared toward accelerating the event of geothermal vitality. The success of this exploration stage, which is able to embody drilling of shallow wells, will decide how a lot we’re capable of generate in type of energy from geothermal sources,” he detailed.
“For electrical energy manufacturing, we have to drill deep wells, and construct an influence plant. At this stage, we’re specializing in creating direct warmth utilisation and persevering with exploration for deeper sources to supply electrical energy sooner or later,” he clarified.
Geothermal potential in Africa
Rwanda is heading in the right direction to put money into geothermal energy as reviews point out that “Africa’s geothermal vitality sector is poised for a big leap, with investments projected to succeed in $35 billion by 2050, probably surpassing Europe’s geothermal capability inside the decade.”
The projection is made by Rystad Vitality which emphasizes the important position that geothermal vitality will play in assembly Africa’s rising vitality calls for. In its report, Rystad Vitality describes the geothermal map of Africa as been primarily based alongside the Nice Rift Valley. The valley, which spans a whopping 6,000 kilometers presents areas of skinny Earth crust making them simpler to entry geothermal sources which are in any other case deep beneath the crust.
For instance, the report cites Kenya’s Olkaria Geothermal Energy Station, which has been operational since 1981 and at the moment delivers almost 900 megawatts and has the potential to clock 5,000 megawatts by 2030.
By comparability, Rwanda’s geothermal vitality comes from a geological space known as the Kivu Rift, that can also be a part of the East African Rift System. Nevertheless, in contrast to the jap department in Kenya and Ethiopia, the Kivu Rift opens to geothermal areas the place temperatures are decrease in comparison with Kenya. For that reason, Rwanda is various makes use of of its geothermal sources.
“Regardless of being dwelling to solely about one gigawatt (GW) of geothermal capability in 2023, which is about half of Europe’s whole output, Africa’s whole put in capability will greater than double by 2030, primarily based solely on already introduced initiatives,” Rystad Vitality reviews.
That’s not all, the report factors out that, if ‘yet-to-be-announced initiatives’ are to be put into the equation, Africa’s capability may triple by 2030. “By 2050, we count on geothermal energy era capability in Africa to broaden to 13 GW, greater than double the anticipated 5.5 GW of put in capability in Europe,” the report attests.
It additionally factors to Kenya and Ethiopia because the anticipated leaders within the progress of Africa’s geothermal sector, and can account for as much as 90 per cent of whole capability.
Kenya: Africa’s chief in geothermal vitality business
Already, Kenya is Africa’s largest producer of geothermal vitality, and on the COP28 summit, it secured a $1 billion deal for a geothermal venture at Suswa with the Indonesian authorities and Masdar-backed Pertamina Geothermal Vitality.
“The deal permits Kenya to develop a 300-megawatt geothermal energy plant that can provide electrical energy to the nationwide grid and help industrial improvement,” the report reveals.
Additional nonetheless, the Geothermal Growth Firm of Kenya secured yet one more take care of AMEA Energy of the UAE which dedicated $800 million to a 200-megawatt Paka Geothermal Undertaking.
In response to the Worldwide Vitality Company (IEA), as of final yr, geothermal vitality accounted for 28 per cent of the put in capability of vitality sources in Kenya, making it the one largest contributor to the nation’s vitality output combine.
“The momentum in geothermal exploration extends past Kenya. East African nations, together with Burundi, Zambia, Tanzania, Uganda, and Rwanda have introduced plans for geothermal exploration,” the report says.
To place it into perspective, the above talked about capability is barely that of a number of East African international locations, when the West a part of the continent is thrown into the image, Africa’s geothermal capability dwarfs that of Europe by far.
