Summary:
Underground hydrogen storage (UHS) coupled to the power-to-gas technology as potential energy storage for renewable energies gained more attention within the last years. In order to plan and calculate the technical and economic feasibility of an UHS, the processes occurring in the subsurface have to be understood. This study presents a successful history match of a hydrogen storage field test, where microbial activity was identified during hydrogen injection. Therefore, the field data was implemented into a dynamic model in the open-source software DuMux. With the used mathematical model, which describes the bio-reactive flow in the reservoir, the change of gas compositions in the withdrawn gas was matched. For the matching process, the initial microbial density and the diffusion coefficients of CO2 and H2 into CH4, were adjusted.
