Forecast of rock mass and ground surface movements caused by the convergence of salt caverns for storage of liquid and gaseous energy carriers

Sroka, Anton, Misa, Rafał, Tajduś, Krzysztof, Klaus, Marcus, Meyer, Stefan, Feldhaus, Bernd 28 September 2017 (has links) (PDF)
The paper presents a method of calculating deformation coefficients for any point situated in the overlying rock mass or on the ground surface. This solution was based on the method presented by Sroka and Schober (1982, 1987), taking into account new theoretical achievements and the current results of in situ measurements.

Speicherung von Wasserstoff im Untergrund – Geologisches Potential in Deutschland

Westhues, Anne 02 February 2024 (has links)
Zur Erreichung der Klimaschutzziele und Dekarbonisierung der Energieerzeugung und Industrie wird in Deutschland und Europa der Ausbau erneuerbaren Energien (v.a. Solar- und Windenergie, Geothermie) vorangetrieben. Die daraus resultierende fluktuierende Stromerzeugung, meist nicht mit dem Strombedarf überlappend, kann in Zukunft nicht mehr durch fossile Energieträger ausgeglichen werden, sondern muss gespeichert werden. Wasserstoff als chemischer Energieträger bietet dazu eine gute Option im Gigawatt- bis Terawattstundenbereich. Als großskalige Speicheroption für Wasserstoff bieten sich Salzkavernen an, die schon jahrzehntelang erprobt und Stand der Technik sind. Die bestehenden Kavernen in Deutschland reichen dabei nicht für die prognostizierten Speicherbedarfe aus, Deutschland verfügt aber über ein großes geologisches Potential, neue Kavernen im Untergrund anzulegen. / To achieve the climate change objectives and decarbonisation of power generation and industry, Germany and Europe are expanding their renewable energies (esp., solar, wind and geothermal energy) vastly. The resulting fluctuation power generation, usually not equalling the current demands, cannot be balanced by fossil fuels in the future and has to be stored instead. Hydrogen as a chemical energy carrier is a good option for the gigawatt- to terawatt-hour range. Salt caverns offer a large-scale storage option for hydrogen that have been used for decades and are state of the art. The existing caverns in Germany are not sufficient for the forecasted storage needs. However, Germany has a large potential for the underground construction of new caverns.
