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: The physical and chemical nature of the ash was explored to determine if fears about health and safety were justified and a protocol was developed that will serve for assessing risks during a future event.

TL;DR: The Hellisheidi carbon injection site is targeted at a lava flow sequence at 400-800m depth with the main aquifer located at 530-m depth as discussed by the authors, and the injected water will have a temperature of ∼25°C and be equilibrated with ∼25 bar pressure of the CO2 gas, and ∼14bar pressure of CO2-H2S−H2 mixture.

TL;DR: In this paper, the dissolution of CO 2 into water during its injection into basalts leading directly to its geologic solubility storage was verified via the successful injection of over 175 m CO 2 dissolved in 5000 m of water into porous rocks located 400-800m below the surface at the Hellisheidi, Iceland CarbFix injection site.

TL;DR: In this article, the underground stratigraphy of the chemical composition and crystallinity of rocks and their alteration state at a targeted field site for injection of CO2-charged waters, the Hellisheidi area in SW Iceland.
