Innovative ClimateTech Startups to Watch

This Kenyan startup is literally sucking CO₂ from the air and selling it Kenyan startup Octavia Carbon is building a Direct Air Carbon Capture (DAC) plant in Gilgil the first of its kind on the continent. It’s a serious engineering play -Uses geothermal energy -Captures 1,000 tonnes of CO₂ from the air annually -Stores it underground in volcanic rock -Sells carbon credits to global buyers This isn’t just another climate headline it’s infrastructure. Quietly being built, tested, and scaled right here. No noise. Just execution.The part that stands out to me? They’re using Kenya’s natural geology and energy mix as a competitive edge. Not trying to clone models from elsewhere they’re making something that fits where they are. I like this kind of work. It’s honest. Capital-intensive, science-heavy, long-term. Not the easiest path for a startup but arguably one of the most impactful. You don’t see many climate-tech teams going this deep into engineering. But maybe we’ll start seeing more. Props to the Octavia Carbon team. #climatetech #carbonremoval #hardtech #directaircapture #kenyatech #deeptech #startups #founderenergy #africa
