Danger Dust - What Else?

From carbonated water to carbonated rock

While most carbon projects focus on offshore storage, CarbFix2's terrestrial approach marks a vital shift: it speeds up natural mineralization processes within basalt, a volcanic rock formed from cooling lava.

At Hellisheiði, CO2 is captured from the geothermal plant and two direct air capture units. The CO2 gas is dissolved in water—much like making a fizzy drink—and pumped deep into porous layers of basalt, where minerals in the rock react with the CO2 and turn it into solid carbonate rock.
