Engineering Professors, Students and Scientists are Converting Air Pollution to Solid Rocks

Columbia University, the Universities of Copenhagen and Reykjavik Energy Iceland engineering professors, students and scientists want to combat climate change


In an attempt to make use of the carbon dioxide emissions, engineering professors, students and scientists from Columbia University, the Universities of Copenhagen and Iceland, and Reykjavik Energy created a solid rock out of a stored carbon dioxide. And the results blew them away.

The process that is supposed to take centuries to achieve was done by the team in just two years. They have successfully converted carbon dioxide into solid rock way shorter than expected.

The process they call CarbFix involves injecting 175 tons of pure carbon dioxide and mixing it with hydrogen sulphide and water. Despite the extreme water pressure, the carbon dissolved. This mixture was pumped deeper into a layer of basaltic rock, where the magic happened: the mixture turned into a stable carbonate mineral in the course of two years.

But there’s more. The study also found that this can even be shortened into just months given the right conditions.

“The results of this study demonstrate that nearly complete in situ CO2 mineralization in basaltic rocks can occur in less than 2 years,” the authors wrote. “Once stored within carbonate minerals, the leakage risk is eliminated and any monitoring program of the storage site can be significantly reduced, thus enhancing storage security and potentially public acceptance.
