The hydrogen consumption and contamination by microbial metabolic processes in the subsurface are a hurdle for sustainable energy storage. Researchers in structural geology want to develop a transparent micromodel of real rocks that make it possible to visualize microbial activities in rock pores and their possible interactions. Such a novel platform will be used in studies on underground hydrogen storage to gain insights into the methane formation process in rock spores. This can help to develop strategies for underground hydrogen storage or underground bio-methanisation.
