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.
