In this book, effective computational methods to facilitate those
pivotal simulations using open-source software are introduced and
discussed with a special focus on the coupled thermo-mechanical behavior
of the rock salt. A cohesive coverage of applying geotechnical modeling
to the subsurface storage of hydrogen produced from renewable energy
sources is accompanied by specific, reproducible example simulations to
provide the reader with direct access to this fascinating and important
field. Energy carriers such as natural gas, hydrogen, oil, and even
compressed air can be stored in subsurface geological formations such as
depleted oil or gas reservoirs, aquifers, and caverns in salt rock. Many
challenges have arisen in the design, safety and environmental impact
assessment of such systems, not the least of which is that large-scale
experimentation is not a feasible option. Therefore, simulation
techniques are central to the design and risk assessment of these and
similar geotechnical facilities.
