Obiettivo del progetto (Objective)
'CO2 sequestration in geological formations containing saline water has been proposed as solution to reduce gas emission to the atmosphere. Multiphase CO2 storage modelling is a highly challenging problem. CO2-MATE will focus on the processes that govern CO2 flow and transport in saline aquifers. The objective of the project is to contribute to the knowledge of the behaviour of CO2 transport in saline aquifers. In particular CO2-MATE aims (1) to advance in the understanding of the CO2 trapping mechanisms and their numerical modelling, (2) to study the influence of heterogeneity in the mixing (dissolution) and spreading (extension) of the CO2 plume and (3) to extend the results on mixing and spreading to reactive multiphase transport modelling of CO2. CO2-MATE has a multidisciplinary approach including advanced physical and mathematical theories and powerful numerical codes. New theoretical and numerical models for CO2 multiphase reactive transport will be developed. CO2-MATE will increase our capacity to model multiphase flow and transport in aquifers, with emphasis on addressing the effect of heterogeneity and chemical reactions.'
Introduzione (Teaser)
Sequestration of carbon dioxide in rocks containing saline water is one possible means of reducing its emission to the atmosphere. This project is concerned with the way in which CO2 moves about in such geological formations.
Descrizione progetto (Article)
One of the most pressing problems facing humanity is how to slow down global warming and climate change.
The emission of CO2 gas to the atmosphere is one of the main causes of warming, so a possible defence is locking it up.
Aquifers carrying saline water could be a suitable place for CO2 sequestration.The 'CO2 Multiphase reactive transport modelling' (CO2-MATE) project used both high-resolution modelling and experimental methods to study CO2 flow and transport in saline-water aquifers.
The aim was reach a better understanding of trapping mechanisms in order to model them realistically.The researchers used a Darcy-Boussinesq model in which the Rayleigh number is the important parameter.
By means of a newly developed theoretical relationship, they showed that the scalar dissipation rate determines the dissolution flux and the rate of fluid mixing.
Computational evidence indicated that under certain conditions the dissolution flux was constant and independent of the Rayleigh number.
Their findings suggest that there is a need for alternative explanations for non-linear scaling.
Project work also showed that the flux dynamics and some macroscopic features of the migrating current could be reproduced using a one-dimensional sharp-interface model.
Other aspects studied included aquifer heterogeneity, and the dissolution of calcite during convective mixing of CO2 in a carbonate aquifer.The results of the work done on CO2-MATE will help in the development of practicable numerical tools.
In turn, this could improve the planning and monitoring of sites where CO2 is injected.
