What Technologies are Covered by Carbfix?
1. Environmental Gas Management (3 Patents)
This is the most prominent area in Carbfix’s IP portfolio. The patents likely focus on systems and processes to manage, neutralize, or sequester environmental gases, particularly CO₂ and other industrial emissions. Technologies under this category may include methods for injecting gases into basaltic rock formations, monitoring gas flow underground, or optimizing gas transport mechanisms. This aligns directly with Carbfix’s core mission of permanent carbon storage via in-situ mineralization.
2. Dispersed Particle Separation (1 Patent)
This area suggests Carbfix is also developing or leveraging technologies to remove or separate suspended particles in gas or liquid phases. This capability is essential when dealing with impure gas streams (e.g., flue gas) before injection into geological formations, ensuring that the mineralization process isn’t hindered by contaminants or particulates.
3. Carbon Dioxide Capture and Separation (1 Patent)
This category covers technologies specifically designed to isolate CO₂ from mixed gas streams. Patents here may involve physical, chemical, or hybrid separation techniques, including absorption columns, membranes, or pressure-swing adsorption systems. This reinforces Carbfix’s upstream capability in capturing CO₂ before its conversion into rock, thus complementing its downstream storage innovation.
