A multi-salinity experiment was conducted in three tight clay-bearing (kaolinite, chlorite, and glauconite) sandstones to study the impact of clay on their petrophysical properties. Chlorite sandstone presented higher electrochemical interaction, followed by glauconite and kaolinite. In the geothermal context, this investigation highlights the importance of ensuring that the correct fluid chemistry is used in clay-bearing geothermal reservoirs.

The European Geosciences Union (EGU) brings together geoscientists from all over Europe and the rest of the world, covering all disciplines of Earth, planetary and space sciences. The Division on Energy, Resources and the Environment (ERE), as part of the EGU, follows an interdisciplinary approach to serve society and provide solutions to challenges of our time and in the future. One task for humankind, for example, is to provide adequate and reliable supplies of affordable energy and other resources, obtained in environmentally sustainable ways, which will be essential for economic prosperity, environmental quality and political stability around the world. This volume of Advances in Geosciences spans the range of topics of the division and continues a series of ten ERE special issues over the course of the last ten years. We incorporate emerging topics into the division ERE along the line and we advocate that every idea and opportunity should be studied and tested.

<b>Storm Franz: Societal and energy impacts in northwest Europe on 11–12 January 2007</b><br>
Anthony J. Kettle<br>
Adv. Geosci., 62, 41–55, https://doi.org/10.5194/adgeo-62-41-2023, 2023<br>
The paper reviews the societal and energy impacts of Storm Franz in Europe on 11–12 November 2007. An analysis is conducted of tide gauges around the North Sea to trace the progression of the storm surge and assess if the surge passage was associated with large measured waves and maritime casualties. A North Sea rogue wave incident had occurred on 1 November 2006, causing damage to the FINO1 research tower, and it is unclear how prevalent these waves are during North Sea storms.

Adv. Geosci., 62, 21–30, https://doi.org/10.5194/adgeo-62-21-2023, 2023<br>
Uranium migration for a close to real case situation is quantified with reactive transport simulations using input data from the deep geothermal borehole Schlattingen, which is near the targeted area in Switzerland, and including the effect of the multi-barrier system on the source term. The hydrogeological system must always be considered in safety assessments since adjacent aquifers have a major impact on the pore water geochemistry, and hence sorption processes.

Adv. Geosci., 62, 11–19, https://doi.org/10.5194/adgeo-62-11-2023, 2023<br>
By testing the strength of granite in compression and tension at a range of deformation rates, we found that the strength increases with faster deformation. This observation highlights that at these rates, relevant for example to geothermal exploration, we have to consider how the rate of deformation impacts the energy released when rocks crack. The results are promising for developing safe procedures for extracting resources from the subsurface.

Alongside a transition from steerable and centralized traditional electricity generation to intermittent and more decentralized renewable electricity generation from solar panels and wind turbines, Dutch energy transition scenarios project a widespread deployment of heat pumps and electric vehicles towards 2050. While clearly contributing to the decarbonization of the Dutch energy system, these developments impose challenges regarding electricity supply-demand mismatch and grid congestion. Spatially resolved electricity demand and supply profiles are required to gain a better insight into where and when such problems are likely to occur within the different scenarios. The present paper focuses on Dutch solar energy supply and features the construction of geodatabases of scenario-specific, spatially resolved electricity generation profiles for building, land and water-bound PV. Country-level PV capacities are geographically distributed based on spatial variance in roof PV potential and availability of suitable land and water use areas. Corresponding electricity generation profiles are constructed using historical meteorological measurements, a diffuse fraction model and a anisotropic transposition model. Empirically found performance ratio profiles are applied to account for a multitude of performance loss factors, including shading, dust and inverter efficiency. In 2050, building-bound capacity is projected to show only limited overlap with both land-bound and water-bound PV capacity. On the other hand, regions with considerable water-bound PV capacity also tend to show considerable land-bound PV capacity. Compared to the present-day situation, yearly country-level PV electricity generation is projected to be a factor 18.5, 15.7, or 7.7 higher in 2050 when respectively following the Regional, National or International Steering scenarios.

Adv. Geosci., 61, 1–21, https://doi.org/10.5194/adgeo-61-1-2023, 2023<br>
This paper presents a conceptual model for the estimation of flood damage to power grids and reviews the available methodologies, to better understand current modelling approaches, challenges, and limitations. The model adopts an interdisciplinary and multi-scale evaluation approach to handle the complex damage mechanisms and capture the cascading effects. In doing so, it adapts to different geographical and economic contexts, allowing stakeholders to implement comprehensive damage assessments.

Data on geothermal properties are notoriously scarce, both on a good temporal and spatial resolution. We compared two data sets of a geothermal well in Bavaria (one had yearly analyses of a great number of ions, the other one tested the water every five minutes but only on a small number of variables) and found that yearly data systematically neglect seasonal variations taking place in the aquifer. Virtual sensors might help to combine the two data sets when the aquifer is well known.

Stormwater could augment our over-drafted urban groundwater resources. Therefore, it is of the utmost importance to fully understand stormwater contaminant presence, transport, and fate in the built environment to design novel or improve conventional treatment systems. Preliminary results have confirmed presence of toxic metals in Barcelona urban runoff (with significant differences depending on the catchment areas), along with decreased metal concentrations at green infrastructure outlets.

Adv. Geosci., 58, 157–175, https://doi.org/10.5194/adgeo-58-157-2023, 2023<br>
The overall impact of climate change is a decrease in the frost damage risk of masonry walls in Tønsberg, Norway. However, an increased frost damage risk is expected from the present to the future conditions for the walls of small, conditioned rooms with higher driving rain load and lower solar radiation gains. Moreover, the freeze-thaw events experienced by the masonry walls of unconditioned, leaky buildings are 20 times more than the ones for the small, conditioned rooms.

Storm Kyrill in January 2007 was one of the worst storms in northern Europe over the past 50 years. The paper presents an overview of the infrastructure and societal impacts of the storm from a compilation of media sources. Energy meteorology impacts were prominent in the large number of power cuts in Europe. An analysis is made of tide gauge data around the North Sea to assess if there had been a recurrence of the rogue wave event at FINO1 from Storm Britta on 1 November 2006.

In 2019, a fiber optic cable was installed in the middle of a deep geothermal production well to the reservoir in Munich, Germany. This cable hangs freely below the pump and allows continuous measurements of the temperature at every meter of the cable. The well was put into operation for the first time in the summer of 2021. We used the fiber optic cable to monitor the temperature profile during production in the reservoir and to quantitatively interpret the flow zones using an inverse model.
