Potential areas for the storage of hydrogen in Schleswig-Holstein

The distribution of salinar rocks worthy of investigation within the saltstock boundary to the establishment of hydrogen/natural gas storage caverns and the maximum acceptable depth of the saltstock roof is shown. Due to their structural development, the salt sticks are internally complex – from the salt rocks of the Zechstein and the red lying – as double salinaries and have overhangs in their flank areas. The depth of the salt canopy (top of the Zechstein and red lagging deposits) up to 1 300 m and NHN served as a maximum depth acceptable for the isolation of caverns (current level of knowledge). From drill results, it can be inferred that locally due to the formation of thick hat rocks, the solable rock can also lie within the designated areas lower than 1 300 m below NHN. The use of the flank areas will not be possible due to the expected, differently formed overhangs.
