DAC and Storage
DAC and Storage
The concentration of carbon dioxide in the atmosphere has been rising steeply in the past sixty years. Capture6’s innovative direct air capture (DAC) solution offers net-negative technology that can remove historical emissions from the atmosphere to restore balance.
Direct Air Capture
Direct air capture (DAC) is a set of engineering techniques that accelerate what trees and plants do in nature – capture carbon dioxide from the atmosphere to sequester carbon. The heart of every Carbon Dioxide Removal (CDR) technique is the chemistry of acid and bases. Capture6’s DAC process is designed for both flexibility while maximizing CO₂ removal through multiple capture pathways.
CO₂ is weakly acidic, and it represents only a tiny fraction – 0.04% – of the atmosphere. We produce our own absorbent for CO₂ capture, sodium hydroxide, which is a strong base that quickly and effectively bonds with CO₂ even at low concentrations. The process does not rely on energy intensive processes such as calcination at high temperatures or compression of CO₂.
Maximum efficiency for less than $100 USD/tonne
Our process can be deployed for capturing CO₂ from ambient air and point sources such as flue gas. Maximizing these multiple capture pathways enable us to drive down the cost of carbon removal. We are able to adapt the core technology to take advantage of various local site conditions, with the flexibility to utilize a wide variety of input sources including seawater, desalination waste streams, saline lakes and aquifers, geothermal brine, artificial brine, and recycled brine.
Capture6 is mitigating environmental and social risks associated with capturing carbon dioxide from ambient air and storing it in a mineralized form.
Mineralization is a clear winner when it comes to DAC storage.
Our CDR solution is not about us, it’s about future generations. The decisions we make today are the building blocks of our future.
Our DAC is one of the world’s leading solutions for permanent and irreversible carbon dioxide removal.
