To reach governmental goals of reduced climate gas exhaust, technologies for improving the production, storage and distribution of renewable energies are necessary. An example is underground storage of hydrogen (H2) gas or hydrogen-methane (H2-CH4) gas mixtures, which can be produced with excessive renewable energies (Power-to-Gas). Salt caverns have excellent geochemical properties to serve as a short- and long-term underground storage for gases. However, the potential oxidation of stored H2 by lithoautotrophic microorganisms is an important but less studied aspect. It is assumed that indigenous sulfate-reducing microorganisms oxidize available H2, and with that produce H2S and other sulfur compounds which in turn lead to corrosion of facility infrastructure and pollution of the gases stored. To investigate these microbial communities I study enrichment and pure cultures with stable-isotope probing (SIP, nanoSIMS, ICPMS) and next-generation sequencing technologies.
