A new paper validates the effectiveness of Carbfix


A new paper published in Nature Communications has independently verified the effectiveness of the Carbfix method. Led by Dr. Pogge von Strandmann, the Carbfix team used Calcium isotopes to quantify the amount of CO2 permanently stored underground. Because certain flavours of Calcium preferentially bind with CO2 to form calcite, we can measure how the composition changes before and after the process of CO2 injection. Earlier measurement indicate that over 90% of the dissolved CO2 is removed through mineralisation in basaltic rocks. By measuring Calcium isotope ratios, we now know that roughly 70% of this turns into calcite whereas the rest goes into other minerals.
