Hydrogen is attracting a growing attention as a protagonist of future energy storage. However, geochemical challenges associated with hydrogen storage in sedimentary formations are still not well defined. Pyrite is a redox sensitive mineral, which is an accessory constituent of the reservoir sandstones. The main aim of our study is to estimate the extent of geochemical reactions among pyrite, porewater and hydrogen. For this purpose, we apply geochemical modeling coupled with experiments with an adequate analytical framework (scanning electron microscopy, ICP-OES).
