Description

The H2STORE project aims to investigate the feasibility of long-term storage of electrical energy in the form of hydrogen in geological formations. The project will identify potential reactions between rocks, pore water, microorganisms, and hydrogen, and then numerically model these reactions using specialized software. To this end, the chemical, mineralogical, petrophysical, and microbiological composition of the rock samples and the associated pore water will be analyzed before and after laboratory experiments in which the sample material is exposed to hydrogen-bearing water. H2STORE thus provides baseline data on the behavior of hydrogen in natural porous media at approximately 40 to 120 °C and a pressure of 4 to 20 MPa. These are conditions that prevail at the current depth levels in the natural gas reservoirs under investigation.
In subproject TP1 at Clausthal University of Technology, experimental investigations will be conducted to determine which petrophysical and geochemical changes in the reservoir rock and the caprock are caused by the action of hydrogen and how they influence the fluid transport properties of reservoir rocks and the barrier properties of the caprock. To this end, batch experiments will be conducted using high-pressure, high-temperature (HPHT) autoclaves and hydrogen reservoir/caprock leaching systems, along with routine and SCAL measurement series to determine possible changes in fluid transport and barrier properties.
In WP2, conducted by Clausthal University of Technology, the Lower Saxony Energy Research Center, and the University of Nancy, the propagation and dynamic changes in the composition of the injected hydrogen will be investigated using modeling and numerical simulations of gas mixing and reactive transport processes. This will also take into account the population dynamics of microbial components and hydraulic instability in such systems. Possible influences of geochemical reactions between rock, organic components, reservoir fluids, and hydrogen, as well as biogenic feedback loops between altered fluid compositions (and the mineral content), are to be clarified.
