Flat salts in Germany (WMS)

Which salt formations are suitable for storing hydrogen or compressed air? In the research project InSpEE-DS, scientists developed requirements and criteria with which possible locations can be assessed even if their exploration is still at an early stage and the knowledge of the structure of the salinares is low. Scientists from DEEP.KBB GmbH, Hannover, together with their project partners of the Federal Institute for Geosciences and Raw Materials and the Leibniz University Hannover, Institute of Geotechnology Hannover, are working together with their project partners on site selection and the construction of storage caverns in flat-stored salts and multiple or double alinars. Such caverns could store renewable energy in the form of hydrogen or compressed air. While the previous InSpEE project limited itself to salt formations of great thickness in northern Germany, different-old salinar horizons have now been studied throughout Germany. For the assessment of potential, depth-line maps of the top and base as well as thickness maps of the stratigraphic unit and reference profiles considered were developed. The information on compressed air and hydrogen storage potential in the individual federal states is linked to the identified areas with usable potential in the layer “storage potential in the federal states”. With the help of the getFeatureInfo request, the user receives further information about the individual geometries. This allows, among other things, access to the criteria catalog data sheet in the layer “Potential storage areas flat salts” of each stratigraphic unit and to the images of drill profiles and bore correlations in the “Drills and Bore Correlations” layer. Spatial selection and material data queries are possible for the following data sets: Drilling, drilling correlations, isobaths, isopaches, boundary elements of the Top Zechstein potential areas, as well as the storage potential in the federal states and potential storage areas of flat-stored cechstone salts. The display scale has a lower limit of 1: 300 000. The geodata are products of a BMWi-funded research project “InSpEE-DS” (running period 2015-2019). The acronym stands for "Information System Salt: Planning bases, selection criteria and potential assessment for the construction of salt caverns for the storage of renewable energies (hydrogen and compressed air) — double salinars and flat-storing salt layers”.
