“…Apart from the Ocnele Mari salt deposit (13), where salt lies at depths of 650 m and can attain a thickness of 500 m, the Tertiary salt deposits do not qualify for cavern construction, as the salt strata is highly folded and imbricated, or is not favored over the presence of salt structures [54], [55]. Ukraine and Belarus ( 15) are excluded from this analysis due to the lack of data for urban and rural areas necessary for the following surface eligibility assessment [56], [57].…”

The role of hydrogen in a future energy system with a high share of variable renewable energy sources (VRES) is regarded as crucial in order to balance fluctuations in electricity generation. These fluctuations can be compensated for by flexibility measures such as the expansion of transmission, flexible generation, larger back-up capacity and storage. Salt cavern storage is the most promising technology due to its large storage capacity, followed by pumped hydro storage. For the underground storage of chemical energy carriers such as hydrogen, salt caverns offer the most promising option owing to their low investment cost, high sealing potential and low cushion gas requirement. This paper provides a suitability assessment of European subsurface salt structures in terms of size, land eligibility and storage capacity. Two distinct cavern volumes of 500,000 m 3 and 750,000 m 3 are considered, with preference being given for salt caverns over bedded salt deposits and salt domes. The storage capacities of individual caverns are estimated on the basis of thermodynamic considerations based on site-specific data. The results are analyzed using three different scenarios: onshore and offshore salt caverns, only onshore salt caverns and only onshore caverns within 50 km of the shore. The overall technical storage potential across Europe is estimated at 84.8 PWhH2, 27% of which constitutes only onshore locations. Furthermore, this capacity decreases to 7.3 PWhH2 with a limitation of 50 km distance from shore. In all cases, Germany has the highest technical storage potential, with a value of 9.4 PWhH2, located onshore only in salt domes in the north of the country. Moreover, Norway has 7.5 PWhH2 of storage potential for offshore caverns, which are all located in the subsurface of the North Sea Basin.

“…Rifting began in the Frasnian but the most active rift phase occurred during the Famennian (Kusznir et al, 1996) and was accompanied by intense volcanism which began in the late Frasnian (Wilson and Lyashkevich, 1996). Volcanic activity was concentrated around the Bragin-Loev Uplift and decreased to both northwest and southeast (Wilson and Lyashkevich, 1996;Garetskii et al, 2004;Rakocinski et al, 2020;Cocker et al, 2017). Active volcanism coincided with the Frasnian -Famennian mass extinction event (Chen and Tucker, 2003;Chen et al, 2013).…”

“…The sedimentary column in the Pripyat Basin comprises rocks of Late Proterozoic, Palaeozoic (Devonian to Permian), Mesozoic (Triassic, Jurassic and Cretaceous) and Cenozoic ages (Figs 2,3). Basement consists of Archean and Lower Proterozoic metamorphic and igneous rocks, and the overlying sedimentary succession can be divided into pre-, syn-and post-rift tectonostratigraphic megasequences (Garetskii et al, 2004;Cocker et al, 2017). An Upper Proterozoic (Vendian) siliciclastic succession rests unconformably on basement (Ayzberg et al, 1989), and the pre-rift megasequence in general consists of Emsian -lower Frasnian siliciclastics (referred to locally as the Vitebsk-Pyarnu, Narov, Stary Oskol and Lan horizons) overlain by limestones and dolostones (Sargai and Semiluki horizons).…”

The sedimentary column at the Rechitsa oilfield in the Pripyat rift basin, Belarus, is dominated by an Upper Devonian synrift succession. The succession includes uppermost Frasnian and mid‐Famennian salt units which are about 1000 m and 2000 m thick respectively. Reservoir rocks consist of sandstones and carbonates in the intra‐, inter‐ and sub‐salt successions. In this paper, the geochemical analysis of 15 oil samples from different stratigraphic intervals at the Rechitsa field is used as a basis for reservoir characterisation. Geochemical studies included biomarker and stable C, N and S isotope analyses.Four genetic oil groups were identified and are referred to as Groups A to D. Oils in Group A came from upper intra‐ and inter‐salt reservoir rocks; the oils are early mature, enriched in heavy (C36+) hydrocarbons, heteroatoms, aryl‐isoprenoids and gammacerane, with low Pr/Ph = 0.6 and a sulphur isotope composition averaging 22.7‰ CDT. Oils in Group B were from sub‐salt reservoirs and are at peak maturity with Pr/Ph = 1, an increased proportion of C27 regular steranes, and a sulphur isotope composition of 8.1‰ CDT. The single oil sample in Group C was from a Proterozoic reservoir. The oil was overmature with a low content of heavy fractions, heteroatoms and steranes; its hopanes composition indicated that it was generated by the same source rock as the oils in Group B. Oils in Group D came from inter‐salt reservoir rocks and were composed of a mixture of Groups A and B oils in roughly equal proportions, as indicated by their average isotope, molecular and biomarker compositions.Observed differences in oil composition were explained in terms of contributions from at least two different source rocks together with variations in source rock maturity. Group A oils were interpreted to have been generated by Famennian carbonate‐rich source rocks containing dominantly marine and bacterial organic matter deposited in an anoxic evaporitic setting. Source rocks for Groups B and C oils were suggested to be composed of OM‐rich marine shales of Frasnian age or older.The geochemical characteristics of the Devonian oils from Rechitsa field, and the oil‐oil and oil‐ source rock correlations reported, will contribute to a better understanding of the petroleum system in the Pripyat Basin although direct oil‐ source rock correlations are not yet available. The presence of at least two source rocks for the Rechitsa oils has been suggested, respectively comprising carbonates in the inter‐salt succession and marine shales and/or carbonates in the sub‐salt succession. The main controls on oil composition in the Devonian reservoir units were the varying contributions from the different source rocks and differences in source rock thermal maturity associated with variations in burial depth and tectonics, together with the stratigraphic distribution of reservoir units which was in turn controlled by the presence of the thick Frasnian and Famennian salt units.
