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 geotechnicalfacilities.

• Current research on applying geotechnical modeling to energy storage and dispatch for renewable energy systems;
• Discusses effective computational methods for conducting design and safety assessments of geotechnical facilities using open-source software;

• Demonstrates how computational simulations can be invaluable in scenarios where large-scale field experimentation is not possible.

Dr. Thomas Nagel leads the "Computational Energy Systems" research group in the Department of Environmental Informatics at the Helmholtz Centre for Environmental Research (UFZ). The Centre studies the complex interactions between humans and the environment in cultivated and damaged landscapes, especially densely populated urban and industrial areas and natural landscapes. The scientists and researchers who work in the Centre develop concepts and processes to help secure the natural foundations of life for future generations.
