Direct Air Capture technology is a form of carbon dioxide removal that separates CO2 from ambient air. The CO2 can then be permanently stored underground or converted into products such as Sustainable Air Fuels (SAFs).
The DAC process involves:
1- The capture (adsorption) phase
During this phase, fans suck in ambient air into the machine, where the air rich in CO2 comes in contact with a filter material.
2- The release (desorption) phase
Upon Saturation, the filter material is indirectly heated under vacuum conditions to release the captured CO2.
3- Geological storage
The released CO2 is then injected deep underground into basalt formations along the Great Rift Valley by our storage partners, where it mineralizes over time, locking it away from the atmosphere for thousands of years.
Our highly modular approach enables us to build, iterate, and scale rapidly. This approach has seen us deploy the Global South's first DAC + Storage plant in just 2.5 years.
We are fully vertically integrated, handling everything from tech development and manufacturing to project development, allowing us to make quick adjustments to drive down costs across the entire DAC value chain.
We offer co-benefits to communities in our deployment region, as per our recently published community engagement whitepaper.
Project Hummingbird is our pilot Direct Air Capture and Storage (DACS) facility, located in Kenya’s central Rift Valley. As the first DACS plant in the Southern Hemisphere, it marks a significant milestone in global carbon removal efforts.
At full capacity, the plant will remove 1,000 tons of CO2 per year, with a projected 10-year operational lifetime. We are commissioning the facility in partnership with a CO2 storage company, who will oversee the permanent geological storage of captured CO2. The CO2 is injected into basaltic rock formations, where it mineralizes, ensuring safe, long-term removal from the atmosphere.
The project will be validated under Puro.earth’s Geologically Stored Carbon (GSC) methodology
To ensure the highest integrity for our carbon credits, we have also partnered with Carbonfuture, the provider of the world’s first independent digital MRV system for DAC.
With the first phase of the project now operational, we are on track to become the second DAC company to issue DAC and geological carbon credits.
