To accelerate the heat transition in Germany the ArtemIS project focuses on the geothermal assessment of medium-depth reservoirs on a region-wide basis, covering all geological play types based on structural and numerical reservoir models. The results are incorporated into the GeotIS internet platform to create interactive “heat transition profiles”, which provide all necessary technical and subsurface data for each play type to perform preliminary geothermal assessment studies.

Adv. Geosci., 65, 189–197, https://doi.org/10.5194/adgeo-65-189-2025, 2025
The world needs a shift from fossil fuels, and geothermal energy is a clean energy source. Aquifer thermal energy storage (ATES) system is an example of a shallow geothermal resource. This study estimates the porosity of the Permo-Triassic Sherwood Sandstone Group for ATES system using borehole nuclear magnetic resonance (BNMR) and Petrophysical models. This study confirms storage capacities in the lower Sherwood Sandstone Group of Northern Ireland that make it suitable for ATES systems.

Adv. Geosci., 65, 181–187, https://doi.org/10.5194/adgeo-65-181-2025, 2025
Salt weathering is influenced by factors such as salt type, concentration, moisture, temperature, and material properties. Environmental conditions and microbial activity can further impact this process. Experimental studies on bacteria in porous systems face challenges from environmental chemistry, detector components, and contamination. Adapting rules and procedures is essential for accurately assessing bacterial activities in salt-bearing porous systems.

Abstract: Impact of climate change on high wind and solar optimal mixes and system costs: the case of France
Joan Delort Ylla, Alexis Tantet, and Philippe Drobinski
Adv. Geosci., 65, 159–169, https://doi.org/10.5194/adgeo-65-159-2025, 2025
Understanding how the electricity generation sector reacts to climate change while large shares of wind and solar energies are introduced is of crucial importance to ensure a clean, secure and affordable electricity provision. We find that in a best case scenario, if we account only for climate change impacts on the wind and solar resource coupled to the demand, then climate change tends to have no adverse economic impacts, while it becomes more interesting to invest in solar than wind energy.

Adv. Geosci., 65, 149–158, https://doi.org/10.5194/adgeo-65-149-2025, 2025
This study reveals new insights to the behaviour of subsurface water flow in fractured bedrock which has important implications for environmental safety of geological storage of spent nuclear fuel, carbon sequestration and other unwanted substances. It shows the relevance of accounting for small scale fracture heterogeneity in models to make accurate predictions on the transit times and pathways water flow takes through bedrock.

Iceland
Abstract: Chemical composition of the discharge fluid from IDDP-2, Reykjanes, Iceland

Adv. Geosci., 65, 141–148, https://doi.org/10.5194/adgeo-65-141-2025, 2025
The Iceland Deep Drilling Project (IDDP) aims to investigate utilization of supercritical fluids. These fluids are considered to provide 10x more energy compared to conventional geothermal wells. During the IDDP-2 well stimulation, casing at about 2300 m depth was damaged and therefore the discharging fluid comes mainly from this depth instead of depths at higher temperature. The chemical composition of the discharge is, however, indicating minor contribution from the deeper depths.

Adv. Geosci., 65, 127–140, https://doi.org/10.5194/adgeo-65-127-2025, 2025
Energy systems across the globe are evolving to meet climate mitigation targets. This requires rapid reductions in fossil fuel use and much more renewable generation. Renewable energy is dependent on the weather. A consequence of this is that there will be periods of low renewable energy production, driven by particular weather conditions. We look at the weather conditions during these periods and show the Indian energy sector could prepare for these events out to 14 days ahead.

We develop a simplified model which describes the geological geometry of the Vendenheim site, the solid and fluid properties were adapted from studies in the area. We implement compute the hydrothermal flow with a temperature dependent density and viscosity in a porous medium, in order to verify if a hydrothermal convective system is compatible with known observations at the Vendenheim site, and to get a better idea of the initial conditions of a model for an induced seismicity model.

The European Geosciences Union (EGU) brought together 22 828 geoscientists in April 2024 from more than 100 countries around the globe, covering all disciplines of Earth, planetary and space sciences, organised in 22 divisions. The division on Energy, Resources and the Environment (ERE) follows an interdisciplinary approach to serve society with provision of solutions to challenges of our time and in the future. For example, adequate and reliable supplies of affordable resources, obtained in environmentally sustainable ways, are and will be essential for economic prosperity, environmental quality and political stability around the world. After a pandemic low of contributions EGU received a record-breaking total number of 19 748 abstracts with 928 coming from ERE. With the highest increase of abstracts of all divisions in ERE, it is obvious that our scientific community recognises more and more the important role of geosciences in sustainable development. This volume of Advances in Geosciences spans the range of topics of the division and continues a series of ERE special issues over the course of the last eleven years.

Concepts of High-Temperature Aquifer Thermal Energy Storage (HT-ATES) are investigated for system application in the German Molasse Basin. We quantify via physics-based numerical modelling the system performance with respect to HT-ATES concept development and provide a predictive analysis of HT-ATES application in the Upper Jurassic reservoir. Results demonstrate a non-uniform layer-specific distribution of the thermal front propagation, while promising heat recovery efficiencies are predicted.

Future glaciations can affect the long-term safety of deep geological repositories for nuclear waste. This study introduces a simple method to assess frequency and duration of ice sheets over the next one million years at locations with past glaciations. The method considers uncertainties in human-caused CO2 emissions and climate change. It is easy to implement for any nuclear waste management organization that need to consider impacts of future ice sheets on long-term safety.

Adv. Geosci., 64, 41–44, https://doi.org/10.5194/adgeo-64-41-2024, 2024
We examined how water quality in aquifers and streams varies along the Besòs catchment, and changes in streams during wet and dry periods. Analysis of water quality data (2013-2023) in open databases shows nutrients and salinity increase towards the outlet, and more markedly during dry periods. Since such dry periods may become more frequent with climate change in this Mediterranean basin, this highlights the importance of controlling pollution sources affecting water quality and availability.

Dealing with the sociotechnical system of nuclear waste needs an integrated perspective. Its global blockage is due to the neglect of relevant issues. The concept of sustainability (passive protection & control) suggests itself as a reference, enabling a stepwise analysis of dimensions: beyond the triad of ecological/economical/social, also temporal, spatial, technical, political, ethical. The proposal avoids simple complexity reduction, either “technical” or “social fix” (volunteers first).

Adv. Geosci., 65, 45–54, https://doi.org/10.5194/adgeo-65-45-2024, 2024
This paper presents a surrogate modelling approach applied to a geochemical system of uranium sorption on clay, relevant for the safety assessment of nuclear waste repositories. The surrogate uses knowledge about the underlying process to recursively partition the dataset into regions of reduced dimensionality. It achieves high accuracy with a competitive prediction throughput, and is a promising method to speedup computationally demanding coupled reactive transport models.

To operate aquifer thermal energy storages in a sustainable way, we located an artesian aquifer other than the aquifer storage in a research wellbore by analyzing the subsurface temperature as monitored with a fiber optic cable in three artesian flow tests. The positioning of the artesian aquifer was validated via numerical modelling. Analyses of the temperature data and numerical modelling enabled determining the profile of flow velocity, flow rate and the depth interval of inflow.

To combat global warming and achieve net-zero CO2 emissions by 2050, Carbon Capture and Storage (CCS) is vital. Despite being a top CO2 emitter globally, Brazil is early in its CCS journey. Our study evaluates the potential of using southern Brazil's saline aquifers for CO2 storage with the aim of supporting Brazil’s efforts to reduce emissions and mitigate climate change. We identify optimal storage sites in two basins, Paraná and Espírito Santo, with ideal locations near existing pipelines.

As groundwater serves as the principal source of water worldwide, its quality is of paramount importance. In this study, the evolution of groundwater quality in California is assessed using the Water Quality Index & Weighted Index Overlay Analysis methods. Several water quality parameters are considered for the analysis, and the results from both methods are compared. The study shows that in most parts of California, groundwater quality is potable, as per WHO guidelines, except in a few places.
