About Direct Air Carbon Capture (DACC)

The science is clear – we have left it too late to cut humanity’s carbon emissions. Now we need to not only take immediate action to decarbonise the global economy, we will also need to remove massive amounts of CO2 from atmospheric air.

Direct Air Carbon Capture (DACC) leverages technology to filter CO2 directly from air, which can then be turned into rocks underground, or used as an industrial gas to replace dirty fossil CO2. Because one car-sized DACC machine can absorb as much CO2 from air as 10 hectares / 25 acres of forest, it is a highly scalable solution to removing CO2 from air, at least in places with enough renewable energy available.

Kenya is such a place, with bountiful geothermal power available, and the potential to produce 10x more at much lower costs if industrial power users can be found to buy some of the resulting electricity. DACC can provide just that stable demand for renewable power, and so help in the fight against energy poverty in East Africa.

About Octavia Carbon

We’re reinventing the Direct Air Carbon Capture industry

Octavia Carbon is the Global South’s first Direct Air Carbon Capture (DACC) company. We aim to use Kenya’s geothermal energy, geology and talent to radically accelerate DACC down the cost curve. Humanity knows how to make climate tech cheap – leveraging global supply chains, we have achieved this for solar PV, batteries, and numerous other tech. Octavia Carbon’s mission is to leverage Kenya’s unique endowments to make the same happen for DACC.

Octavia Carbon designs and builds DACC machines using well-proven amine-based air filters to supply our global partners with cost-effective CO2 solutions. At the same time, we are working to bring online East Africa’s large potential for DACC + geological CO2 sequestration. Our first commercial machines, coming online in early 2023, will cement us as a trusted partner. By 2025, our aim is to make Kenya the world’s most cost-effective hub to build and deploy DACC machines.

Frequently Asked Questions (FAQ)

Why DACC in Kenya? 

3 reasons: Geology, renewables & talent.

Kenya’s rift valley has the right geology to safely store air-captured CO2 for millennia. Most of Kenya’s power grid is 100% renewable, thanks to Kenya’s abundant geothermal and hydro-power. Finally, Kenya has a young and innovative population that experiences the ravages of climate change first-hand, and so has a strong incentive to fix it. 

Is this new technology? 

Yes, it is a technology that is still in development. First suggested in 1999, DAC technology is yet to be fully scaled-up, but its development is being accelerated by policies and incentives from governments and private sector initiatives around the globe. 

Octavia Carbon is the first DACC company in Kenya and Africa.   

How does this compare to other ways of CO2 removal? 

For some context, one car sized DACC machine can absorb as much CO2 from air as 10 hectares / 25 acres of forest. DACC is a highly scalable solution to removing CO2 from air and it can safely lock up CO2 for millennia, which equals how long humanity’s emissions will stay in the atmosphere. 

DACC is integral to achieve the world’s climate goals of limit global warming to well below 2°C, which is why the world’s leading climate scientists now include it in their modelling.

This is not to say that planting trees is an inadequate way of climate conservation, but rather that it should work hand in hand, with DACC amongst other efforts.

Isn’t DACC too expensive? 

At the moment, DACC is cost-competitive for some of the small-scale CO2 users today.

While DACC removal is still expensive – costing up to about $1000 per ton of CO2 (~$1,000 / tCO2) – there is reliable trajectory to bring this below $100 per ton of CO2 (<$100 / tCO2) by 2030, and progressively lower beyond that.

DACC costs are still higher than other forms of carbon removal. It is also important to state that DACC also guarantees the exact amount of CO2 removed from the air is locked up forever by turning it into a rock.

Many organizations see the value of DACC as per leading scientists’ recommendations and are very willing to pay premium price for DACC today to help decrease the cost curve (very similar methodology as to how solar energy achieved this).

Kenya’s abundant geothermal energy, suitable geology and abundant talent will be key ingredients in speeding up how quickly DACC’s cost curve can come down.
