Carbfix

Carbfix is the world’s first CO2 mineral storage operator, having mineralized 85 thousand tons of CO2 underground in Iceland since 2012 using proprietary technology. Carbfix injects CO2 dissolved in water into basaltic rocks, where it turns into stone in under two years through accelerated natural processes. This certified, safe, permanent, and cost-effective carbon storage solution is ripe for significant upscaling both in Iceland and worldwide. Their unique process has sparked over 100 published scientific papers and surprised scientists of its ability.

The path of carbon:

Carbon is either captured from the atmosphere through Direct Air Capture or from the source of emissions.

Emission source sequestration uses large filters at the chimneys of factories or power plants. Direct air capture pulls in air and filters out the carbon.

At Carbfix, CO2 is dissolved in water, the solution is the injected into earths crust. There, the dissolved CO2 combine with cations such as calcium, magnesium and iron to form carbonates. These carbonates fill up pores within rocks and eventually turn to stone. This form of storage is stable for thousands of years.

Carbfix refers to it as nature‘s way of storing carbon in rocks, accelerated.

These scientific papers explain in amore complex way

How much carbon can they store?

Iceland has the potential to store an estimated 400 Gt CO2 (400 billion tonnes CO2), significantly larger than the estimated 18,500 Gt CO2 stemming from human emissions.

What about water scarcity?

Carbfix has developed the scientific basis for using seawater to dissolve CO2, prior to injection, thus expanding the applicability of the technology to water scarce regions, coastal and offshore areas.
