Kenya’s Octavia will get $3.9M seed to take away carbon from air

As requires pressing local weather motion persist, applied sciences to assist take away the heat-trapping greenhouse gases from the ambiance are additionally rising globally.

In Africa, Octavia Carbon, a Direct Air Seize (DAC) startup is main the efforts. Octavia, based in Kenya two years in the past, builds DAC machines that it makes use of to seize carbon, a greenhouse gasoline that’s the largest contributor of worldwide warming, from the air for storage underground.

Octavia, which begun capturing carbon in February after a interval of growing the tech, now plans to construct extra machines so as to add to its current two gadgets with a carbon seize capability of fifty tonnes per yr. This comes because the startup plans to scale carbon elimination in Kenya after closing a $3.9 million seed spherical and, it says, $1.1 million within the advance sale of carbon credit.

Octavia raised the fairness funding in a spherical co-led by Lateral Frontiers and E4E Africa, with participation from Catalyst Fund, Launch Africa, Fondation Botnar, and Renew Capital.

Octavia’s co-founder and CEO Martin Freimüller, informed TechCrunch the startup expects to achieve a seize capability of 1,500 tons per yr starting in 2025 when working at capability and a storage web site run by associate firm Cella Mineral Storage comes on-line.

“We’ve been growing the tech and now we’re taking it out of the lab for carbon elimination at scale within the subject,” mentioned Freimüller, who co-founded the startup with Duncan Kariuki, a mechanical engineer.

Freimüller defined that whereas Octavia captures carbon from air and liquefies it, the startup has teamed up with Cella, a carbon sequestration startup that can inject it into the bottom for storage.  

Injection of the startup’s first batch of captured carbon is predicted to occur earlier than the yr ends, and Freimüller mentioned the undertaking can be among the many first ones on the earth to show captured carbon into rock underground.

“As soon as now we have that liquid carbon dioxide, we give that to our storage associate, and they might kind of inject it underground at excessive pressures to seep into volcanic rock pores, and people are fairly wealthy in calcium and magnesium that reacts with the CO2 to type carbonate minerals like calcium carbonate or limestone,” mentioned Freimüller. “Naturally occurring supplies, naturally occurring course of and we’re simply accelerating that in geologic areas the place that hasn’t actually occurred over lengthy durations of time.”

Kenya’s aggressive edge

Freimüller mentioned the geology of Kenya was one of many causes the startup arrange operations domestically, explaining that the nation’s Rift Valley area has the fitting rock formation for carbon storage.

“Kenya is de facto distinctive in having the East African Rift Valley, and that’s actually vital for 2 causes. The geology is nice as a result of it has porous rocks, volcanic rocks — particularly basalts . . . that really can retailer CO2 underground. And the capability of that geology is large. You could possibly retailer all of humanity’s cumulative CO2 thus far in simply Kenya, mainly, as a result of now we have one thing like 8,600 cubic kilometers of that pore house within the East African Rift Valley,” he mentioned.

Capturing carbon from air can also be vitality intensive, and for Octavia, the abundance of renewable vitality, particularly geothermal, in Kenya was the opposite issue that impressed the founders to arrange operations within the East African nation. They are saying utilizing renewable vitality offers Octavia a aggressive edge over its friends within the developed world that use fossil fuels for his or her DAC operations, then purchase renewable vitality credit (which is counter-productive).

Globally, 27 DAC crops with seize capability of 0.01 Mt CO2 per yr have been commissioned in Europe, North America, Japan and Center East. Out of those crops, solely Climeworks Orca plant in Iceland, which grew to become operational in 2021; the International thermostat headquarters plant in Colorado; and the Heirloom facility in California, each of which launched final yr, at present seize greater than 1,000 tons of CO2 per yr.

Extra are anticipated because the trade grows. Actually, 130 DAC amenities are at present underneath growth globally to seize 65 MtCO2 per yr, a capability wanted by 2030 to understand web zero emissions by 2050.

Freimüller says it won’t be a straightforward endeavor, however it’s doable.

“Who would have thought you could transfer an SUV round on batteries? That has been accomplished too and that’s finally the facility that engineering has to kind of change the sides inside what’s doable,” he mentioned.

Freimüller labored beforehand at Dalberg, a worldwide consulting agency, centered on worldwide growth methods. It’s the place he first got here throughout the huge alternatives that the local weather sector presents.

His startup has since grown to a crew of 60, 40 of whom are engineers doing analysis and growth, with the others specializing in bench scale chemistry, which includes testing supplies, strategies and chemical processes.

As Octavia, an Xprize Carbon Removing finalist, scales its operations, it goals to supply extra DAC and storage carbon credit to develop its revenues. The startup says the Danish carbon elimination market Klimate is considered one of its largest purchasers, and that it has secured 12 altogether up to now.

“For a deep tech firm, it’s uncommon to have that many purchasers at seed stage,” mentioned Freimüller. “It took numerous work to do to deliver on these clients, nevertheless it’s additionally honest to say that there’s numerous demand available in the market for what we’re doing.”
