NEWS: Formal agreement signed to sequester CO2 into Icelandic basaltic rocks

The research will be a combined program consisting of field scale injection of CO2 at Hellisheidi, laboratory based experiments, large scale plug-flow experiments, study of natural CO2 waters as natural analogue and state of the art geochemical modelling. The project involves scientists at the University of Iceland, Columbia University I New York, the CNRS in Toulouse, France and Reykjavik Energy. To see the full press release, please click here .

Toulouse Center for CO2 Sequestration Research

This center groups together a wide variety of projects and expertise currently ongoing in Toulouse aimed at perfecting techniques to sequester CO2 once it is injected into the subsurface.

The goal of the Toulouse Center for CO2 Sequestration Research is to provide the fundamental basis for predicting the degree to which stable carbonates will precipitate in the subsurface.

The CO2 leads to the acidification of the fluids present at the injection site. This acidification provokes the dissolution of mineral phases, including carbonates such as calcite. As these minerals dissolve, liberating cations to solution, the fluid neutralizes, eventually leading to the precipitation of carbon-bearing minerals.

Current efforts at the Toulouse Center for CO2 Sequestration Research are focused on:

1) Determining the rates of dissolution of primary silicate and carbonate minerals in the presence and absence of CO2.

2) Developing an improved data base describing the solubility of minerals in the presence of dissolved CO2.

3) Measuring the precipitation rates of carbon-bearing minerals at conditions typical of likely CO2 sequestration sites.
