Issue 12/2016 - "Carbon Sequestration" Project Turns CO2 into "Stone"

For a long time, carbon capture and storage technology has been seen as an important solution to global warming, that is, to separate carbon dioxide from gases produced by industrial production or burning fossil fuels, and then inject it into a certain depth of underground rock for storage
.
According to foreign media, an international scientific research team reported that they injected carbon dioxide into underground basalt layers and converted carbon dioxide into solid carbonate with the help of natural chemical reactions
.

The project is jointly implemented by Columbia University in the United States, the University of Iceland, Reykjavik Energy Company in Iceland, the University of Southampton and other institutions, the researchers first mixed the previously collected carbon dioxide with water, and then injected it into
the basalt layer 400~800 meters deep.
The results showed that 95%~98% of the injected carbon dioxide content calcified (that is, converted to solid carbonate)
in less than two years.
Solid carbonate minerals pose no risk of leakage, so they can permanently and environmentally sound sequester carbon dioxide
