- Rwanda is contemplating agro-processes to reinforce its geothermal assets 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 power affords the East African nation a strategy to diversify its sources of electrical energy and cut back reliance on imported power. In accordance with 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 power useful resource, owing to the prices associated to electrical energy technology utilizing geothermal assets.
“We’re specializing in creating direct warmth utilization and persevering with exploration for deeper assets to provide electrical energy sooner or later,” Eugene Karangwa, Head of Different Energies and Geothermal at Rwanda Vitality Group (REG), introduced not too long ago. He stated Rwanda is trying to make the most of its geothermal assets instantly for heating and drying, and never simply electrical energy technology.
The Rwandan official added that the nation is collaborating with the United Nations, the UN Atmosphere Programme for capability constructing on the way to greatest use their geothermal assets.
Because of the associated prices, and the character of our geothermal sources, the official stated, Rwanda is contemplating a number of functions 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 functions similar to milk pasteurization, crop drying, and chilly storage to forestall post-harvest losses and all these are choices we’re , he informed media.
“One downside we’re addressing is the drying of rice to take care of its high quality from farm to manufacturing unit. There are additionally points with preserving vegetables and fruit, which may gain advantage from geothermal warmth,” famous Karangwa.

Challenges to Rwanda geothermal exploration plan
In accordance with 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 undertaking combining geothermal with photo voltaic power 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 overall $800,000 required within the exploration of the Gisenyi geothermal prospect.
“REG can also be collaborating with European and Kenyan universities below the African Union and European Union Renewable Vitality framework below 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 interact inexperienced power companions to ascertain what he described as ‘a risk-sharing mechanism.’
“Which means to draw personal funding, a fund could possibly be arrange the place a non-public firm drills wells, and if the wells are unsuccessful, a portion of the price can be coated by the fund, lowering the chance for the personal sector,” he defined.
On this regard, Rwanda is at present in talks with the Geothermal Threat Mitigation Facility (GRMF), he stated and in the identical vein, Rwanda is leveraging know-how for exploration actions, the official stated.
“If we use the newest applied sciences, we can conduct deeper analysis aimed toward accelerating the event of geothermal power. 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 assets to provide electrical energy sooner or later,” he clarified.
Geothermal potential in Africa
Rwanda is heading in the right direction to spend money on geothermal energy as reviews point out that “Africa’s geothermal power sector is poised for a major 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 essential function that geothermal power will play in assembly Africa’s rising power 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 affords areas of skinny Earth crust making them simpler to entry geothermal assets which can be 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 present delivers practically 900 megawatts and has the potential to clock 5,000 megawatts by 2030.
By comparability, Rwanda’s geothermal power comes from a geological space referred to 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 assets.
“Regardless of being dwelling to solely about one gigawatt (GW) of geothermal capability in 2023, which is about half of Europe’s complete output, Africa’s complete put in capability will greater than double by 2030, primarily based solely on already introduced tasks,” Rystad Vitality reviews.
That’s not all, the report factors out that, if ‘yet-to-be-announced tasks’ are to be put into the equation, Africa’s capability might triple by 2030. “By 2050, we count on geothermal energy technology 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 development of Africa’s geothermal sector, and can account for as much as 90 per cent of complete capability.
Kenya: Africa’s chief in geothermal power business
Already, Kenya is Africa’s largest producer of geothermal power, and on the COP28 summit, it secured a $1 billion deal for a geothermal undertaking 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 may provide electrical energy to the nationwide grid and help industrial improvement,” the report reveals.
Additional nonetheless, the Geothermal Growth Firm of Kenya secured one more cope with AMEA Energy of the UAE which dedicated $800 million to a 200-megawatt Paka Geothermal Challenge.
In accordance with the Worldwide Vitality Company (IEA), as of final yr, geothermal power accounted for 28 per cent of the put in capability of power sources in Kenya, making it the only largest contributor to the nation’s power 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 just that of a number of East African nations, when the West a part of the continent is thrown into the image, Africa’s geothermal capability dwarfs that of Europe by far.
