Insights into the effects of anthropogenic activities on oil reservoir microbiome and metabolic potential
Mbow, Fatou; Akbari, Ali; Dopffel, Nicole; Schneider, Konstantin; Mukherjee, Soujatya; Meckenstock, Rainer (Peer reviewed; Journal article, 2023)Microbial communities have long been observed in oil reservoirs, where the subsurface conditions are major drivers shaping their structure and functions. Furthermore, anthropogenic activities such as water flooding during ... -
The light in the dark: In-situ biorefinement of crude oil to hydrogen using typical oil reservoir Thermotoga strains
Veshareh, Moein Jahanbani; poulsen, morten; Nick, Hamidreza M.; Feilberg, Karen; Eftekhari, Ali A; Dopffel, Nicole (Peer reviewed; Journal article, 2021)H2 is a CO2 free energy carrier that can be produced biologically through dark fermentation using specific bacteria. In general, biological production of H2 needs a carbon source and is more efficient at higher temperatures. ... -
Microbial hydrogen consumption leads to a significant pH increase under high-saline-conditions: implications for hydrogen storage in salt caverns
Dopffel, Nicole; Mayers, Kyle; Kedir, Abduljelil; Alagic, Edin; An-Stepec, Biwen; Djurhuus, Ketil; Boldt, Dabiel; Beeder, Janiche; Hoth, Silvan (Peer reviewed; Journal article, 2023)Salt caverns have been successfully used for natural gas storage globally since the 1940s and are now under consideration for hydrogen (H2) storage, which is needed in large quantities to decarbonize the economy to finally ... -
Microbial induced wettability alteration with implications for Underground Hydrogen Storage
Boon, Maartje; Buntic, Ivan; Ahmad, Kadir; Dopffel, Nicole; Peters, Catherine; Hajibeygi, Hadi (Peer reviewed; Journal article, 2024)Characterization of the microbial activity impacts on transport and storage of hydrogen is a crucial aspect of successful Underground Hydrogen Storage (UHS). Microbes can use hydrogen for their metabolism, which can then ... -
Microbial life in salt caverns and their influence on H2 storage – Current knowledge and open questions
Dopffel, Nicole; An-Stepec, Biwen; Bombach, Petra; Wagner, Martin; Passaris, Evan (Peer reviewed; Journal article, 2024)Hydrogen will be one of the key components for renewable energy storage in the future energy systems as it can be stored in significant volumes to overcome daily to seasonal energy fluctuations. Subsurface storage in salt ... -
