Mineralization

Carbfix

Carbfix is a pioneer in the development and deployment of CO2 storage through mineralization in basaltic rock formations. Since its first pilot project in Iceland in 2012, Carbfix has safely and permanently mineralized over 100 thousand tons of CO2. The Carbfix method accelerates an entirely natural process, which is a part of the carbon cycle, by which CO2 rapidly reacts with elements in underground rock formations and transforms into stable carbonate minerals. In other words, it turns CO2 into stone. The CO2 is captured, either from a point source or directly from the atmosphere, dissolved in water, and injected into the bedrock at a minimum of 500 m depth. By dissolving the CO2 in water, the CO2 is no longer buoyant and has the tendency to sink rather than rise back to the surface. The CO2-charged water accelerates metal release from basalt and formation of solid carbonate minerals. Once stored as a mineral, the CO2 is immobilized for geological time scales and is considered permanently stored. The Carbfix method has global potential, reactive rock formations such as basalts are among the most common rock types on Earth and can be found on every continent. Carbfix strives to reduce emissions for responsible companies in the hard-to-abate industries across Europe and wider, as well as teaming up with Direct Air Capture (DAC) providers for permanent storage of the captured CO2. Carbfix mission is to significantly contribute to climate recovery through worldwide scaling and further development of underground CO₂ mineral storage.
