In WP4, RAG, together with BOKU, is working on proving the chemical resistance of the overburden of the deposit during the injection and storage of up to 100% hydrogen. Based on the previous investigations, further knowledge and data on the flow of hydrogen through porous media will be collected and microbial activity in hydrogen-saturated porous media will be investigated. The results of WP4 will provide valuable insights in the field of geochemistry and microbiology.
