Abstract

A system for carbon mineralization comprises- an underground reservoir comprising sedimentary rock, the sedimentary rock comprising multiple first particles, interparticle porosity and native water, wherein said first particles have a specific surface area of between 10-200 m²/g and comprise volcanic ash particles and silicate material comprising one or more divalent cations, wherein the sedimentary rock comprises a first layer sandwiched between two second sedimentary layers,- a CO2 source,- one or more injection wells for accessing the underground reservoir, the injection well comprising at least one superficial first opening configured to be connected to the CO₂ source, and at least one subjacent second opening defining an injection point, and- a pumping system configured to supply a predefined flow rate of the CO₂ source from the injection point, forcing CO₂ to mix with the native water, and further forcing the mixture to contact the surface area of the first particles.
