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.本数据集展示了盐丘边界内值得开展研究的盐岩（salinar rocks）分布，以及用于建设氢气/天然气储库洞穴的盐丘最大可接受顶板深度。受构造演化影响，盐柱内部构造复杂——其赋存地层包含蔡希斯坦统（Zechstein）盐岩与红色盖层（red lagging deposits），且属于双重盐系构造，侧翼区域发育悬垂构造。盐盖层（蔡希斯坦统与红色盖层的顶部）最大埋深可达1300米，NHN为当前认知水平下储库洞穴隔离所需的最大可接受埋深。根据钻探结果可推断，局部区域因厚层帽状岩层的形成，指定范围内的可溶盐岩埋深也可能低于NHN基准面以下1300米。由于预期会出现不同形态的悬垂构造，侧翼区域无法被开发利用。
