Carbfix turns CO2 into stone out of thin air!

Carbfix turns CO2 into stone out of thin air!
On the outskirts of Reykjavík, next to the Hellisheidi geothermal powerplant, CarbFix and Climeworks are extracting CO2 out of thin air and turning it into rock!

According to the International Energy Agency (IEA), annual global CO2 emissions in 2019 were a striking 33 gigatons of carbon (GtC), in line with every year of the past decade. Let that number sink in. One gigaton is equal to one billion metric tons, more than a hundred million African elephants!

While the numbers are hard to grasp, it is clear that this needs to change. There has been tremendous progress in implementing renewables globally, but unfortunately, emissions are not yet trending downward. What if there were a way to pull CO2 out of the air? While it sounds like magic, a collaborative effort between the CarbFix and Swiss company Climeworks does just that!

On the outskirts of Reykjavík, next to the Hellisheidi geothermal powerplant, CarbFix and Climeworks are extracting CO2 out of thin air and turning it into rock!

Essentially, CarbFix is accelerating a natural process that usually occurs over geological timespans. Simply put, CO2 and other acid gases are produced from industrial sources, such as coal and gas burning, cement and steel manufacturing, and even geothermal wells. These gases are captured and pumped into scrubbers that shower the gasses with pure water. The gasses dissolve into the water and are injected into the subsurface basaltic rock formations, where they turn into stable minerals (rock) in approximately two years.
