Marieni, Chiara; Voigt, Martin; Clark, Deirdre E.; Gíslason, Sigurður R.; Oelkers, Eric H. (2021): Mineralization potential of water-dissolved CO2 and H2S injected into basalts as function of temperature: Freshwater versus Seawater. In International Journal of Greenhouse Gas Control 109, p. 103357. DOI: 10.1016/j.ijggc.2021.103357.

„Mineralization of freshwater-dissolved gases, such as CO₂ and H₂S, in subsurface mafic rocks is a successful permanent gas storage strategy. To apply this approach globally, the composition of locally available water must be considered. In this study, reaction path models were run to estimate the rate and extent of gas mineralization reactions during gas-charged freshwater and seawater injection into basalts at temperatures of 260, 170, 100, and 25°C.“
