Kenya is in line to turn out to be a hub for carbon seize and storage, after Swiss firm Climeworks introduced it’s wanting into choices for a large-scale facility within the nation.
Climework’s potential entry into the nation is a significant increase for Kenya’s ambitions to turn out to be a regional chief in carbon seize. Climeworks has vital credentials within the business, having already developed the world’s first main business direct air seize and storage facility in Iceland. The agency raised 600m Swiss francs ($650m) from main international traders in its most up-to-date funding spherical.
In line with the UK’s Nationwide Grid, carbon seize includes the seize of CO2 emissions from industrial processes, corresponding to metal and cement manufacturing, or from the burning of fossil fuels in energy technology. This carbon is then transported from the place it was produced, by way of ship or in a pipeline, and saved deep underground in geological formations.
Daniel Nathan, chief challenge growth officer at Climeworks, advised African Enterprise that Kenya supplies “a quite distinctive alternative”. The East African Rift Valley gives perfect circumstances for storing carbon in its mineralised type, he says. And Kenya’s geothermal sources present a supply of renewable energy for DAC (direct air seize) machines, together with the warmth wanted for the machines to function.
Individually, the East African nation can be set to host the world’s second largest pilot for direct air seize (DAC) know-how. Venture Hummingbird, led by startup Octavia Carbon, will intention to seize 1,000 tonnes of carbon yearly from subsequent yr. The captured carbon can be mineralised by Octavia’s associate firm, Cella Mineral Storage, and saved within the huge chasm of the Rift Valley for hundreds of thousands of years.

Mineralisation
Climeworks is exploring alternatives in Kenya alongside Nice Carbon Valley, an organization looking for to ascertain industrial parks in Kenya that might comprise DAC services and depend on geothermal vitality.
Kenya is already the world’s seventh-largest producer of geothermal energy, though it nonetheless has vital untapped potential.
The expansion of Kenya’s DAC business is sweet information for geothermal builders. DAC corporations could be main off-takers of electrical energy and warmth generated by geothermal vitality, which might make geothermal tasks extra financially viable. Carbon seize can due to this fact “be a catalyst for constructing a number of the capability that may very well be accessible,” says Nathan.
Nathan says that Nice Carbon Valley will play an important position in serving to Climeworks consider the alternatives and put together for market entry. The agency may also assist Climeworks to pick out a associate for mineralising the carbon that it captures.
Mineralisation methods contain speeding-up the method of turning carbon dioxide from a gasoline to a carbonate mineral. This course of, left to nature, would take many hundreds of years however Climeworks’ associate Carbfix says it has achieved this in lower than two years at its challenge in Iceland. CO2 is injected into water and saved in basalt rock – a substance present in abundance within the Rift Valley.
Different carbon seize tasks all over the world contain the utilisation of captured CO2. Certainly, CO2 has all kinds of makes use of, together with in bottling crops, in greenhouses, or within the manufacturing of e-fuels. Whereas Nathan doesn’t dismiss the chance that Climeworks might provide CO2 for a challenge of this type, he stresses that the corporate’s main purpose is to retailer captured carbon.
In doing so, Climeworks is ready to increase income by means of the sale of carbon credit. Credit from DAC are far dearer than credit bought by tasks that seize carbon by means of tree planting. Nonetheless, the quantity of carbon captured and mineralised by corporations like Climeworks will be simply quantified – and patrons of carbon credit will be assured that mineralised carbon can be saved securely for a just about infinite period of time. Climeworks introduced final month that it’s working to realize certification beneath the usual developed by verification supplier Puro.earth.
A closing resolution on whether or not to put money into Kenya remains to be a “few years” away, Nathan says. The corporate must discover a appropriate website for capturing and storing carbon, the place both geothermal vitality or one other renewable energy supply is on the market. Nathan provides that navigating the allowing course of and securing entry to finance may also be key challenges.
However he’s assured that obstacles will be overcome, enabling Kenya to profit from the benefits bestowed by geology. “We’re optimistic that the subsequent couple of years will give us all these solutions,” he says.
