Abstract

The commercial-scale deployment of in-situ mineralization necessitates a comprehensive understanding of near and far field CO2-rock interactions to ensure storage permanence and alignment with regulatory requirements through detailed characterization, injection, and monitoring activities. Site characterization plans which emphasize site-specific geochemical and hydraulic data collection aim to appropriately parameterize reactive transport modeling, capturing mineralization trapping mechanisms, and guiding injection and monitoring strategies. Commercial deployment of mineralization storage will benefit from monitoring techniques uniquely designed to assess dynamic pore pressure environments due to mineralization effects. Identifying unique operational considerations and risks, paired with holistic monitoring and verification strategies, will be key to commercial deployment of mineralization storage.
