Direct Air Capture and CO2 Storage Pilot Success in Kenya

Cella Mineral Storage and Octavia Carbon have completed a successful early-stage CO2 injection test in Kenya's Rift Valley. This project demonstrates the ability to capture carbon from the air and store it permanently in basalt formations through mineralization. The pilot utilized adapted oilfield techniques to inject pure-phase CO2, aiming for higher efficiency and lower water usage than previous mineralization projects. This development suggests a shift toward distributed, boutique storage solutions for stranded emissions.

Octavia Carbon and Cella just hit a milestone in Kenya with a small scale CO2 injection. It is a proof of concept for DAC paired with basalt storage. Worth a look for anyone tracking how fast these pilots are moving from lab to field.

Half a ton is a start, but the real question is the energy load for the DAC units. Does the local grid have the headroom for this to scale, or are they relying on dedicated renewables? The energy intensity usually kills the economics.

The mention of boutique storage for stranded emissions is the interesting part here. If they can move away from the hub and spoke model, it changes the regulatory requirements for transport and pipeline easements.

True, but boutique storage needs a clear accounting standard. Who verifies the mineralization in these distributed sites? Without a strict MRV framework, these credits won't fetch a premium in the voluntary market.

Using oilfield techniques for carbon storage is a smart way to reuse existing labor skills. I wonder what the maintenance cost looks like for these injection wells in basalt over a ten year period.
