| Abstract | In this paper, the motivation and the scientific concept of a number of European modelling groups is presented sharing the idea of the common development of a generic modelling framework for coupled physico-chemical processes characterising energy-related geoscientific applications. Within the context of the European policy of transformation of energy technologies, the geological underground becomes a specific focus of attention in terms of: i) energy source, ii) energy storage, and iii) energy waste disposal. All these geoscientific applications have the observation of very similar complex multiphysics porous media processes in the subsurface formations in common. Thus, assessing the behaviour of geo-reservoirs under different operating conditions requires the analysis of complex coupled processes at the reservoir scale. The full length and time scales for which the performance of geological sites must be assessed are not amenable to direct investigation by laboratory studies or field investigations. The only practical option for predicting the long-term behaviour of geo-reservoirs is numerical analysis, constrained by the understanding gained from the relatively short-term laboratory and field-scale experiments available, and natural analogue systems. Modelling and simulation of thermo-hydro-mechanical-chemical processes in the subsurface require the development of sophisticated mathematical models, numerical algorithms and software tools that have to be adapted to the needs of real world applications. As the development of scientific software for complex geoscientific problems is beyond the capabilities of individual groups, the main innovation of the presented cooperative initiative would be the development of an integrated framework, capable of simulating all known relevant processes involved in the geotechnical use of the subsurface. This facilitates substantial progress in understanding of long-term fate of the considered formations, particularly directed to large scale deployment of relevant technologies. Integrated model and software concepts for the simulation of energy-related coupled processes have to be approved by benchmark and test site simulations, and provide the opportunity of predictive in silico analyses of diverse mechanisms on reservoir scale. |
