Simulating geologic co-sequestration of carbon dioxide and hydrogen sulfide in a basalt formation.

Highlights: [•] Mineral sequestration of CO₂ in Columbia River Basalt under field conditions is predicted to occur within several decades. [•] Mineral sequestration of co-injected H₂S is predicted to occur within several years. [•] Modeled rates are consistent with laboratory predictions. [•] Binary interaction parameters for the solubility of CO₂ and H₂S in pure water and brine are detailed. [Copyright &y& Elsevier]
