Flat layered salts in Germany (WMS)

Which salt formations are suitable for storing hydrogen or compressed air? In the InSpEE-DS research project, scientists developed requirements and criteria for the assessment of suitable sites even if their exploration is still at an early stage and there is little knowledge of the salinaries’ structures. Scientists at DEEP.KBB GmbH in Hanover, worked together with their project partners at the Federal Institute for Geosciences and Natural Resources and the Leibniz University Hanover, Institute for Geotechnics Hanover, to develop the planning basis for the site selection and for the construction of storage caverns in flat layered salt and multiple or double saliniferous formations. Such caverns could store renewable energy in the form of hydrogen or compressed air. While the previous project InSpEE was limited to salt formations of great thickness in Northern Germany, salt horizons of different ages have now been examined all over Germany. To estimate the potential, depth contour maps of the top and the base as well as thickness maps of the respective stratigraphic units and reference profiles were developed. The information on compressed air and hydrogen storage potential in the federal states is linked to the identified areas with usable potential in the Layer Storage potential in the federal states (Speicherpotenzial in den Bundesländern). Via the getFeatureInfo request, the user obtains additional information on the different geometries. This enables access to the criteria catalog data sheet in the layer Potential storage areas for flat layered salt (Potenzielle Speichergebiete flach lagernde Salze) of each stratigraphic unit and to the illustrations of borehole profiles and borehole correlations in the layers Boreholes (Bohrungen) and Borehole correlations (Bohrungskorrelationen). Spatial selection and data queries are possible for the following data sets: Boreholes (Bohrungen), Borehole correlations (Bohrungskorrelationen), Isobath (Isobathen), Isopach (Isopachen), Boundary elements of the potential areas Top Zechstein (Begrenzungselemente der Potenzialgebiete Top Zechstein), Storage potential in the federal states (Speicherpotenzial in den Bundesändern) and potential storage areas in the flat layered Zechstein salt (Potenzielle Speichergebiete flach lagernde Zechsteinsalze). The scale of display is limited to a minimum of 1:300.000. This geographic information is product of a BMWi-funded research project "InSpEE-DS" running from the year 2015 to 2019. The acronym stands for "Information system salt: planning basis, selection criteria and estimation of the potential for the construction of salt caverns for the storage of renewable energies (hydrogen and compressed air) - double saline and flat salt layers".
