(Kitco News) - Verifiable and near permanent are the advantages to using reactive minerals for carbon sequestration, said CO2Lock's CEO Cooper Quinn.
Earlier this month Quinn spoke to mining audiences manager Michael McCrae and Kitco correspondent Paul Harris on Kitco Roundtable.
CO2Lock is focused on carbon sequestration using rocks that react to carbon in the air and bind with it. The process works by storing CO2 in hard rock called serpentinized peridotites. The brucite-rich form is a superior host with significantly faster and larger storage potential than basalts, writes CO2Lock on its investor presentation. The company is exploring in-situ and ex-situ processes as the best means to exploit the technique. CO2Lock is a subsidiary of FPX Nickel, which is advancing a project in central B.C.
Quinn said that binding carbon to minerals has some advantages over growing trees or other methods of carbon sequestration. CO2Lock's method is verifiable and near permanent.
"Mineralizing that CO2...that is then stable over geologic time," said Quinn.
