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.
