Cavern flight Field of salt rock caverns (Norbert Böttcher, UFZ) Large scale energy storage is a requirement to overcome the natural temporal fluctuations associated with energy production from renewable sources. One of many approaches of energy storage is the conversion of electrical energy into secondary energy carriers such as hydrogen, methane or compressed air. Subsurface storage formations such as saline aquifers, depleted gas reservoirs or artificial salt caverns show a large storage potential for those energy carriers. The ANGUS+ Project investigates the possible impacts of subsurface energy storage on the underground. Therefore, numerical models are used to simulate various scenarios of energy storage operations and their implications. These models are parametrised based on literature studies and laboratory experiments. Based on these investigations, new concepts of underground spatial planning and guidelines on subsurface energy storage will be developed by the project partners.
