Mineral Carbonation of CO2

Development and evaluation of a thermodynamic dataset for phases of interest in CO2 mineral sequestration in basaltic rocks

“…Matter et al, 2008;Oelkers et al, 2008;Gíslason et al, 2010;Aradóttir et al, 2011, for further detail). Extensive research has been conducted in order to characterize the pilot injection site at Hellisheidi with respect to stratigraphy, hydrology as well as other physical and chemical properties (e.g.…”

The efficient long-term inhibition of forsterite dissolution by common soil bacteria and fungi at Earth surface conditions

“…The reactivity of forsterite and its silicate alteration products has received increasing attention as a potential source material for the divalent cations required to carbonate CO 2 during carbon storage efforts (e.g. Giammar et al, 2005;Oelkers and Schott, 2005;Bearat et al, 2006;Matter et al, 2007;Oelkers et al, 2008;Dufaud et al, 2009;Prigiobbe et al, 2009;Matter and Kelemen, 2009;King et al, 2010;Daval et al, 2011;Guyot et al, 2011;Broecker, 2012;Kohler et al, 2013;Gislason and Oelkers, 2014;Sissmann et al, 2014). This interest has led to a large number of studies aimed at characterizing forsterite dissolution behavior and rates at various fluid compositions and temperatures (Luce et al, 1972;Sanemasa et al, 1972, Grandstaff, 1978, 1986, Murphy and Helgeson, 1987, 1989Blum andLasaga, 1988, Banfield et al, 1990;Walther, 1991, 1992;Casey and Westrich, 1992, Awad et al, 2000, Chen and Brantley, 2000, Rosso and Rimstidt, 2000, Pokrovsky and Schott, 2000a, 2000b, Oelkers, 2001b, Giammar et al, 2005, Hänchen et al, 2006, Olsen and Rimstidt, 2008Davis et al, 2009;Rimstidt et al, 2012;Olsson et al, 2012;Plümper et al, 201...…”

Mineral CO2 sequestration by environmental biotechnological processes

“…Although, a portion of the limestone has metamorphic and igneous origins, the large sedimentary portion of these carbonate rocks shows that mineral CO 2 sequestration is a geologically stable process with a high potential for CO 2 sequestration (Holland, 1978;Walker et al, 1981b). The effectiveness of the process for mitigation purposes has however been limited due to the slow kinetics of the CO 2 -silicate reactions (Oelkers et al, 2008). The idea of distributing finely powdered alkaline silicate minerals over land areas as a geo-engineering solution is to enhance the efficiency of mineral CO 2 sequestration by increasing the reactive surface area (Schuiling & Krijgsman, 2006).…”

“…The process is based on natural weathering of the silicate minerals (Seifritz, 1990). The effectiveness of the process for climate change mitigation purposes is however limited due to the slow kinetics of the CO 2 -silicate reactions (Oelkers et al, 2008). Lackner et al 1995 introduced a number of chemical and physical methods to increase the rate of the process by accelerating the weathering rate of silicate minerals and precipitation rate of carbonate minerals (Lackner et al, 1995).…”
