“…Several projects are in progress or have just been completed studying for energy purposes the storage of pure hydrogen in salt caverns (H2STORE, HyUnder, HyStock, Rostock H, STOPIL H2, etc.) and in gas fields (SunStorage and HyChico projects) or possibly mixed with CO2 in deep saline aquifers (Underground bio-methanation concept [7]) or with CH4 (SunStorage and HyChico projects). A benchmarking study of the different options for high-pressure hydrogen storage was carried out as part of the European project HyUnder [8].…”

“…However, it lacked a quantitative assessment of the processes of microbial growth and H2 consumption relevant for H2 storage. Strobel et al [29] summarized the concept and potential of underground methanation using experimental data from the Sun Storage project. These authors highlighted controls on the growth of methanogens and changes in gas composition due to methanogenesis, but did not quantify microbial growth.…”

“…For H 2 storage, one of the challenges the technology faces is quantifying how much H 2 will be lost due to microbial conversion. In some cases, the conversion of H 2 and CO 2 to CH 4 might be actively encouraged to create huge underground bioreactors to supply energy to households (Strobel et al, 2020).…”
