Ratouis (2022): Permanent and secure geological storage of CO2 by in-situ carbon mineralization
on carbfix.com, author: Thomas Ratouis
„Climeworks and Carbfix developed and independent quality and assurance leader DNV validated the world’s first full-chain certification methodology dedicated to carbon dioxide removal via direct air capture and underground mineralization storage. It provides the requirements for stringent standards by which measurement and reporting of Climeworks‘ carbon dioxide removal and Carbfix‘s permanent mineralization can be third-party verified. With this methodology, Climeworks and Carbfix aim to contribute to the standardization and scale-up of high-quality, permanent removals.“
Abstract: This methodology article outlines processes, requirements, and emission quantification for permanent and secure CO2 capture, transport, and geological storage by rapid insitu carbon mineralization. In situ carbon mineralization replicates and accelerates natural processes, in which carbon dioxide is dissolved in water and interacts with reactive rock formations to form stable minerals providing a permanent and safe carbon sink.
