The H2STORE project was tasked with investigating long-term storage of electrical energy in the form of hydrogen in porous underground gas storages. In doing so possible interactions between the geology, reservoir fluid, microorganisms and hydrogen were observed and subsequently numerically modelled. To this end, sample material were exposed to hydrogen-bearing fluids whereby their individual chemical, mineralogical, petrophysical and microbial compositions of the reservoir samples and their associated pore fluid were examined prior to and after experimentation. H2STORE therefore provides the basis information on the behavior of hydrogen in porous media in conditions ranging from 40 to 120°C and pressures ranging from 4 to 20 MPa. The conditions implemented originate from genuine natural gas storages.
Subproject TP1 aimed to investigate the petrophysical and geochemical changes in the reservoir and surrounding overburden rocks by investigating the effects of hydrogen on the flow characteristics of the reservoir and the sealing efficiency of the overbearing cap rock. For this purpose batch experiments, representing the hydrogen-reservoir-cap rock-porefluid systems, in High Pressure and High Temperature Autoclaves were employed. The samples underwent a series of investigations including SCAL analyses to investigate possible changes in fluid transport and barrier properties.
In Subproject TP2, the TU Clausthal in cooperation with the Energieforschungszentrum Niedersachsen and University of Lorraine were tasked with carrying out the modeling and numerical simulations depicting the propagation and dynamic changes in composition of injected hydrogen gas and their corresponding reactive transport processes. Population dynamics of the microbial components and hydraulic instabilities were adressed. Possible geochemical reactions between the rock and organic matter with reservoir fluids and hydrogen as well as biogenic regeneration were to be clarified.
