Amidst the rapid development of renewable energy, intermittency and instability energy supply pose severe challenges impose higher requirements on storage systems. Among various technologies, coupled approach power-to-hydrogen (H2) underground H2 (UHS) offers advantages such as extended duration large-scale capacity, making it highly promising for future development. However, during UHS, particularly in porous media, microbial metabolic processes methanogenesis, acetogenesis, sulfate reduction may lead to consumption production byproducts. These activities can impact efficiency safety UHS both positively negatively. Therefore, this paper provides a comprehensive review experimental, numerical, field studies interactions within aiming capture research progress elucidate effects. It begins by outlining primary types key involved. Subsequently, introduces experimental approaches investigating gas-water-rock-microbe interfacial properties, models simulators used numerical studies, procedures implemented trials. Furthermore, analyzes discusses their positive negative impacts focusing aspects consumption, flow, safety. Based these insights, recommendations site selection, engineering operations, on-site monitoring well potential directions, are provided.

Assessment of the in situ biomethanation potential of a deep aquifer used for natural gas storage

FEMS Microbiology Ecology, Journal Year: 2024, Volume and Issue: 100(6)

Published: April 23, 2024

The dihydrogen (H2) sector is undergoing development and will require massive storage solutions. To minimize costs, the conversion of underground geological sites, such as deep aquifers, used for natural gas into future hydrogen sites favored scenario. However, these contain microorganisms capable consuming H2, mainly sulfate reducers methanogens. Methanogenesis is, therefore expected but its intensity must be evaluated. Here, in a aquifer storage, 17 were sampled, with low concentrations ranging from 21.9 to 197.8 µM slow renewal formation water. H2-selected communities composed families Methanobacteriaceae Methanothermobacteriaceae genera Desulfovibrio, Thermodesulfovibrio, Desulforamulus. Experiments done under different conditions, reduction, well methanogenesis, demonstrated presence H2 or H2/CO2 (80/20) phase, without calcite/site rock. These metabolisms led an increase pH up 10.2 certain conditions (without CO2). results suggest competition CO2 between lithoautotrophs carbonate mineral precipitation, which could limit microbial consumption.

Microbiological insight into various underground gas storages in Vienna Basin focusing on methanogenic Archaea

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: Dec. 13, 2023

In recent years, there has been a growing interest in extending the potential of underground gas storage (UGS) facilities to hydrogen and carbon dioxide storage. However, this transition raises concerns regarding microbial reactions, which could convert into methane. It is crucial gain comprehensive understanding communities within any UGS designated for study, water samples from surface technologies 7 different objects located Vienna Basin were studied using both molecular biology methods cultivation methods. Results 16S rRNA sequencing revealed that proportion archaea groundwater ranged 20 58%, with methanogens being predominant. Some collected contained up 87% methanogens. Various species isolated individual wells, including Methanobacterium sp., Methanocalculus Methanolobus sp. or Methanosarcina We also examined presence sulfate-reducing bacteria known be involved microbially induced corrosion identified genus Desulfovibrio samples. second part our we contextualized data by comparing it available terrestrial subsurface environments worldwide. This allowed us discern patterns correlations between types based on environmental conditions. Our findings reveal all analyzed groups samples, suggests possibility unintended hydrogen-to-methane conversion associated financial losses. Nevertheless, prevalence results highlights environment, can effectively leveraged as bioreactor methane, particularly context Power-to-Methane technology.

A bio‐reactive transport model for biomethanation in hydrogen underground storage sites

Published: Oct. 15, 2024

Abstract Underground biomethanation, which relies on the subsurface microbial activity to convert hydrogen and carbon dioxide into methane, is a promising approach support capture, utilization, storage technology. The process involves injecting with captured CO 2 depleted oil gas reservoirs or aquifers colonized by hydrogenotrophic methanogens that can these two substrates methane. Despite attractiveness of this technology, there are still uncertainties about efficiency conversion process, particularly impact parameters. To investigate we relied bio‐reactive transport model mimic growth decay, consumption substrates, reactants products. It was found methane concentration peaks near injection well when fraction in range 75% 80% injected composition. In addition, noticeable sulfide be produced due ions brine. Using Kozeny‐Carman relation, an attempt made correlate reduced porosity permeability. then revealed substrate microbes leads drastic increase population subsurface, reduce petrophysical properties reservoir, especially wellbore area. results obtained from series parametric analyses showed gas, pressure, spacing, rate some most important parameters contributing biomethanation process. © 2024 Society Chemical Industry John Wiley & Sons, Ltd.
