Octavia Carbon: Pioneering Direct Air Capture in the Global South
Company Overview
Octavia Carbon is a climate technology company headquartered in Nairobi, Kenya, recognized as the Global South's first Direct Air Capture (DAC) and storage entity. Founded in June 2022, the company specializes in designing, manufacturing, and deploying engineered solutions that extract carbon dioxide (CO2) directly from the atmosphere. By integrating Kenya?s abundant geothermal energy and unique basaltic geology, Octavia Carbon aims to position Africa as a leader in the global carbon removal industry.
As of early 2026, the company has grown into a vertically integrated organization that manages the entire value chain; from laboratory R&D and machine manufacturing to project development and carbon credit issuance. With a workforce that is over 99% Kenyan, the company emphasizes local talent and "green industrialization" to address the global climate crisis while driving regional economic growth.
Mission and Vision
Octavia Carbon's core mission is to reverse the effects of climate change and accelerate the end of the fossil fuel age by scaling carbon removal technology. The company's vision is to make Kenya a global hub for DAC by leveraging its renewable energy grid (currently over 93% renewable) and its geological capacity for permanent CO2 storage. By 2030, Octavia Carbon aims to deploy more than 10 million tons of annual DAC and storage capacity in Kenya and export its specialized machines globally.
Core Technology and Process
Octavia Carbon utilizes a "Solid Sorbent" Direct Air Capture approach. Unlike traditional carbon capture which filters emissions at the point of origin (such as factory flues), DAC removes existing CO2 from the ambient air, making it a "net-negative" technology.
The Three-Phase Carbon Removal Cycle
The company's technology operates in a three-step cycle designed for maximum efficiency and durability:
Adsorption Phase (Capture): Industrial fans pull ambient air into a DAC machine (such as the "Nelion" model). The air passes through specialized chemical filters containing solid amine sorbents. These sorbents selectively bind to CO2 molecules, effectively scrubbing them from the air while the remaining nitrogen and oxygen pass back into the atmosphere.
Desorption Phase (Release): Once the filters are saturated, the system is sealed, and a vacuum is applied. Octavia Carbon utilizes "Temperature-Vacuum Swing" (TVS) technology. The key innovation is the use of geothermal waste heat (at approximately 80-100?C) to heat the filters. This causes the sorbents to release the CO2 in a concentrated, pure stream while regenerating the filter material for its next cycle.
Mineralization and Storage: The pure CO2 is compressed and liquefied. In partnership with storage specialist Cella Mineral Storage, the liquid CO2 is injected into the basaltic rock formations of the Kenyan Rift Valley. Through a natural chemical reaction called mineralization, the CO2 reacts with the rock to form solid carbonate minerals (e.g., limestone) within a few years, ensuring the carbon is locked away permanently for thousands of years.

Products and Services
1. Direct Air Capture Machines
Octavia Carbon designs and builds its hardware in-house at its Nairobi facility.
* "Thursday" Unit: The company's first prototype, a modular unit capable of removing approximately one ton of CO2 per year.
* "Nelion" Series: The current flagship model used in commercial deployments, featuring modular architecture that allows for rapid scaling and easy maintenance in field environments.
2. Verified Carbon Removal Credits
The primary commercial product of Octavia Carbon is the sale of high-permanence carbon credits. These credits are sold to organizations looking to neutralize their residual emissions through high-quality, durable removal rather than traditional avoidance offsets.
* Certification: Credits are validated under the Puro.earth Geologically Stored Carbon (GSC) methodology, which is ICROA-certified.
* Verification: The company employs independent digital Measurement, Reporting, and Verification (MRV) systems provided by partners like Carbonfuture to ensure transparency and "additionality."
3. Subscription Packages for Individuals and Small Businesses
Octavia Carbon offers tiered digital packages that allow supporters to fund specific amounts of carbon removal:
* Explorer: For capturing 1?9 kg of CO2.
* Voyager: For capturing 10?49 kg of CO2.
* Pioneer: For capturing 50?99 kg of CO2.
* Trailblazer: For capturing 100+ kg of CO2.
Key Projects: Project Hummingbird
Project Hummingbird is Octavia Carbon's flagship commercial pilot facility located in Naivasha, along the Great Rift Valley. It is the first DAC+Storage plant in the Southern Hemisphere and the African continent.
Capacity: The project is designed to scale to a capacity of 1,000 tons of CO2 removal annually.
Integration: The facility is co-located with geothermal energy sources, utilizing waste heat to provide over 80% of the energy required for the desorption process.
Impact: Beyond carbon removal, Project Hummingbird serves as a proof-of-concept for African-led deep tech innovation, creating dozens of highly skilled jobs and providing local community benefits such as educational scholarships and water infrastructure.
The Kenyan Advantage: Geothermal and Geology
Octavia Carbon's strategy is built on two unique regional advantages that allow it to compete on cost with global DAC leaders:
Geothermal Waste Heat: DAC is traditionally energy-intensive because of the heat required to release captured CO2. Kenya is a global leader in geothermal energy. By tapping into the "waste" heat from existing geothermal plants, Octavia Carbon significantly reduces its operational expenditures and carbon footprint.
Basaltic Formations: The Kenyan Rift Valley contains vast deposits of reactive basalt rock. This geology is ideal for "in-situ" mineralization, which is considered the safest and most permanent form of carbon storage available today.
Strategic Partnerships
The company collaborates with a network of global climate and technology partners:
* Cella Mineral Storage: The primary geological storage partner responsible for injection and mineralization.
* Puro.earth: The carbon credit registry and standard-setting body.
* Tomorrow's Air: A travel-focused platform that aggregates demand for carbon removal from the global tourism sector.
* Vaisala: A provider of high-precision CO2 measurement sensors used to optimize machine performance.
* Investors: Backed by various climate-focused venture capital firms and funds, including Launch Africa Ventures and the Milkywire Climate Transformation Fund.
Socio-Economic Impact
Octavia Carbon positions itself as a catalyst for "Climate Justice." By building the technology locally in Kenya, they ensure that the economic benefits of the nascent carbon removal industry?estimated to become a trillion-dollar market by 2050?remain within the Global South. This includes:
* Job Creation: Creating career paths for Kenyan mechanical, chemical, and software engineers.
* Grid Subsidization: By providing a "baseload" demand for geothermal energy that might otherwise go unused, Octavia Carbon helps make new renewable energy projects in the region more financially viable.
* Community Engagement: Actively working with local Maasai and Kikuyu communities in project areas to ensure transparent land use and shared benefits.
