TL;DR: This study demonstrates for the first time the permanent disposal of CO2 as environmentally benign carbonate minerals in basaltic rocks and demonstrates that the safe long-term storage of anthropogenic CO2 emissions through mineralization can be far faster than previously postulated.

TL;DR: CarbFix as discussed by the authors injects CO2 into permeable basaltic rocks in an attempt to form carbonate minerals directly through a coupled dissolution-precipitation process.

TL;DR: In this article, the authors review, synthesize, and extend inferences from a variety of sources, including data from studies on natural peridotite carbonation processes, carbonation kinetics, feedback between permeability and volume change via reaction-driven cracking, and proposed methods for enhancing the rate of natural mineral carbonation via in situ processes (rather than ex situ processes).

TL;DR: In this paper, the thermodynamic and kinetic basis for mineral storage of carbon dioxide in basaltic rock, and how this storage can be optimized is described, and the feasibility to fix CO2 by carbonation in basascic rocks will be tested in the CarbFix project by injection of CO2 charged waters into basaltitic rocks in SW Iceland, laboratory experiments, and studies of natural analogues, and geochemical modelling.

TL;DR: In this article, a small-scale CO2 injection test in mafic and metasedimentary rocks was conducted using a single-well push-pull test strategy CO2 saturated water (pH = 35) was injected into a hydraulically isolated and permeable aquifer interval to study the acid neutralization capacity of Ca, Mg silicate rocks and to estimate in situ cation release rates Release rates for Ca,Mg, and Na were calculated by use of solute compositions of water samples retrieved after the CO 2 injection, the incubation time of the injected
