Olivine has been put forward as the prime candidate mineral for marine enhanced rock weathering (mERW), but at present, no peer-reviewed results are available from larger-scale field studies in coastal areas, so the information about olivine dissolution in marine systems is largely derived from laboratory experiments. As a result, key uncertainties remain concerning the efficiency, CO2 sequestration potential, and impact of olivine-based mERW under relevant field conditions. In this review, the authors summarize recent research advancements to bridge the gap between existing laboratory results and the real-world environment in which mERW is intended to take place.
