“…Similar to previous studies from high CO 2 environments [11, 67, 68], including the Eger subsurface [20, 32], we frequently identified taxa belonging to the Comamonadaceae family. While the Comamonadaceae contain a diverse group of water and soil bacteria, the here discovered genera Acidovorax, Rhodoferax, Hydrogenphaga , and Curivbacter have all been detected in high CO 2 environments [12, 13, 69, 70], and have been suggested to fix or utilize CO 2 or H 2 in their likely mixotrophic lifestyle [11, 71]. Another finding supporting a somewhat CO 2 driven bacterial community is the frequent detection of the taxa Desulfosporosinus and Sulfurimonas , both of which have been discovered in high CO 2 and acidic environments [11, 13, 72-74].…”

The Eger Rift subsurface is characterized by frequent seismic activity and consistently high CO2 concentrations, making it a unique deep biosphere ecosystem and a suitable site to study the interactions between volcanism, tectonics, and microbiological activity. Pulses of geogenic H2 during earthquakes may provide substrates for methanogenic and chemolithotrophic processes, but very little is currently known about the role of subsurface microorganisms and their cellular processes in this type of environment. To assess the impact of geologic activity on microbial life, we analyzed the geological, geochemical, and microbiological composition of rock and sediment samples from a 240 m deep drill core, running across six lithostratigraphic zones. In addition, we evaluated diversity as well as metabolic attributes of bacterial and archaeal communities. Our investigation revealed a distinct low biomass community, with a surprisingly diverse Archaea population, providing strong support that methanogenic archaea reside in the Eger subsurface. Geochemical analysis revealed sulfate and sodium concentrations as high as 1000 mg L-1 in sediment samples from a depth between 50 and 100 m and in weathered rock samples collected below 200 m. Most microbial signatures could be assigned to common soil and water bacteria, which together with the occurrence of freshwater Cyanobacteria at specific depths, emphasize the heterogenous, groundwater movement driven nature of this terrestrial subsurface environment. Although not as frequently and abundantly as initially expected, our investigations also found evidence for anaerobic, autotrophic, and acidophilic communities in Eger Rift sediments, as sulfur cycling taxa like Thiohalophilus and Desulfosporosinus were specifically enriched at depths below 100 m. The detection of methanogenic, halophilic, and ammonia oxidizing archaeal populations demonstrate that the unique features of the Eger Rift subsurface environment provide the foundation for diverse types of microbial life, including the microbial utilization of geologically derived CO2 and when available H2, as a primary energy source.

“…Pellizzari et al (2017) demonstrated that injectivity loss at the CO 2 storage site in Ketzin was related to microbially mediated processes. Exposure to organics (drill mud components and biodegradation products) caused changes in autochthonous microbial community and acceleration in activity of some microbial groups.…”

Mineralogical and geochemical analysis of Fe-phases in drill-cores from the Triassic Stuttgart Formation at Ketzin CO2 storage site before CO2 arrival

Reactive iron (Fe) oxides and sheet silicatebound Fe in reservoir rocks may affect the subsurface storage of CO 2 through several processes by changing the capacity to buffer the acidification by CO 2 and the permeability of the reservoir rock: (1) the reduction of threevalent Fe in anoxic environments can lead to an increase in pH, (2) under sulphidic conditions, Fe may drive sulphur cycling and lead to the formation of pyrite, and (3) the leaching of Fe from sheet silicates may affect silicate diagenesis. In order to evaluate the importance of Fe-reduction on the CO 2 reservoir, we analysed the Fe geochemistry in drill-cores from the Triassic Stuttgart Formation (Schilfsandstein) recovered from the monitoring well at the CO 2 test injection site near Ketzin, Germany.The reservoir rock is a porous, poorly to moderately cohesive fluvial sandstone containing up to 2-4 wt% reactive Fe. Based on a sequential extraction, most Fe falls into the dithionite-extractable Fe-fraction and Fe bound to sheet silicates, whereby some Fe in the dithionite-extractable Fe-fraction may have been leached from illite and smectite. Illite and smectite were detected in core samples by X-ray diffraction and confirmed as the main Fe-containing mineral phases by X-ray absorption spectroscopy. Chlorite is also present, but likely does not contribute much to the high amount of Fe in the silicate-bound fraction. The organic carbon content of the reservoir rock is extremely low (\0.3 wt%), thus likely limiting microbial Fe-reduction or sulphate reduction despite relatively high concentrations of reactive Fe-mineral phases in the reservoir rock and sulphate in the reservoir fluid. Both processes could, however, be fuelled by organic matter that is mobilized by This article is part of a Topical Collection in Environmental Earth Sciences on ''Subsurface Energy storage'', guest-edited by
