HyStorIES - Wasserstoff­speicherung im Untergrund

The EU project “HyStorIES — Hydrogen Storage In European Subsurface” inves­ti­gated the feasi­bility of hydrogen storage in porous under­ground storage facilities. The project thus formed the comple­mentary part of the H2UGS R&D project, in which the storage of hydrogen in salt caverns was researched.

Using formation water and rock samples from various European under­ground storage facilities, the MicroPro team inves­ti­gated the popula­tions and microbial processes that may be associated with hydrogen injection in the micro­bio­lo­gical sub-project. In order to determine the H2 stimu­lation potential of microbial processes, extensive laboratory and model tests were carried out under normal and high-pressure conditions.

With one exception, various groups of hydrogen-consuming micro­or­ga­nisms were found in all samples. The results of the micro­bio­lo­gical simulation tests were incor­po­rated into geoche­mical models of bio-reactivity in 3D models in order to evaluate the expected effects on the scale of opera­tional storage. As a result of the micro­bio­lo­gical site inves­ti­ga­tions, a simplified microbial activity risk assessment flowchart was created using only the reservoir charac­te­ristics and a priori available or measurable information.
