The major mineral that constitutes the carbonate rock is calcite. Carbonate rocks including their mineral calcite have been widely studied in terms of adsorption of the fluids such as CO 2 and CH 4 [[21], [22], [23]]. However, the existing literature on the interaction between hydrogen and carbonate, specifically with mineral calcite, is limited.
