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.
