Data underlying the research of hydrogen solution exposure at seasonal timescale does not impact geomechanical properties of clay-rich sandstones rocks

This dataset contains results from six-month static exposure experiments on rock samples subjected to brine-only and hydrogen-rich brine environments under varying confining pressures (100–300 bar). It also includes monotonic loading test data post-exposure. The data supports research on geochemical and mechanical changes relevant to underground hydrogen storage.

本数据集包含针对岩石样品开展的为期六个月静态暴露实验结果，实验中样品分别置于纯卤水（brine）与富氢卤水环境中，并施加100–300 bar的变围压（confining pressure）；同时包含暴露实验结束后的单调加载测试（monotonic loading test）数据。该数据集可支撑与地下储氢（underground hydrogen storage）相关的地球化学与力学变化研究。
