Thermo-mechanical investigation of salt caverns for short-term hydrogen storage
To investigate the temperature influence on the cavern capacity, a numerical model was developed in order to simulate the thermo-mechanical behaviour of salt caverns during cyclic hydrogen storage. The model ...

Closing Remarks
This book gave an introduction into the thermo-mechanical modelling of rock salt in general, and of gas storage in salt caverns in particular. There are many topics that were not discussed here but that are ve...

Simulating Gas Storage in Salt Caverns
Salt caverns are artificial cavities in salt formations, which are usually used for long-term storage of hydrocarbons such as black oil or natural gas. At least two facilities, located in MacIntosh, USA (Power...

Basics of Thermomechanics and Inelasticity
Rock salt can undergo large inelastic deformations over extended periods of time. Many analyses, however, refer to time intervals and mechanical loads that cause deformations for which the small-strain assumpt...

Chapter
Theory
In this chapter we briefly glance at basic concepts of porous medium theory (Sect. 2.1.1) and thermal processes of multiphase media (Sect. 2.1.2). We will study the mathematical description of thermal processe...

Deformation Processes
This section presents a set of closed form solutions of 3D problems on shear and torsion. The associated simulation exercises have been checked by OGS; they may serve as verification tests.

Evaluation of thermal equations of state for CO2 in numerical simulations
Three commonly used thermal equations of state for carbon dioxide, as well as the ideal gas law, have been compared against a large number of measurement data taken from the literature. Complex equations of st...

A systematic benchmarking approach for geologic CO2 injection and storage
The idea of this paper is twofold. On one hand, we propose a general systematic for benchmarking of CO2 modelling. On the other hand, we integrate material from the CLEAN project into this framework to demonstrat...
