Geosci., 67, 161–171, https://doi.org/10.5194/adgeo-67-161-2026, 2026<br> We studied how the chemical composition of water in rocks affects the movement of uranium, which is important for the safety of nuclear waste disposal sites. Using computer models, we found that water chemistry inside the host rock for the waste is more decisive for the transport of uranium than groundwater chemistry in adjacent rocks. These findings help improve site selection for a disposal site by indicating which conditions are suitable and less suitable to safely isolate radioactive waste. 2026-02-12T23:27:36+01:00 https://doi.org/10.5194/adgeo-67-137-2026 <b>Evaluation of a unidirectional ATES for thermal energy supply of the State Hospital Graz South, Austria</b><br> Nikolaus Petschacher and Vilmos Vasvári<br> Adv. Geosci., 67, 137–159, https://doi.org/10.5194/adgeo-67-137-2026, 2026<br> In cities, large thermal plumes often limit groundwater-based heating and cooling. Unidirectional ATES reverses the well arrangement so heat and cold are transported by natural groundwater flow and reused seasonally. At Graz South Hospital, modeling shows efficient energy recovery, strongly reduced off-site impacts, and high potential for climate-friendly energy supply in space-constrained urban areas. 2026-02-10T23:27:36+01:00 https://doi.org/10.5194/adgeo-67-129-2026 <b>Combining interbasin water replenishment and solar capacities for sustainable energy and water management in the catchment of Lake Velence</b><br> Attila Kálmán, Máté Chappon, and Katalin Bene<br> Adv. Geosci., 67, 129–136, https://doi.org/10.5194/adgeo-67-129-2026, 2026<br> Climate change has negative effects on water resources. It creates conflicts among stakeholders at Lake Velence. This region is undegoing rapid urbanization and economic expansion, while includes significant wetland areas, some are under protection. It has high density of solar panel installations. Our research proposes a water transfer system, using renewable energy potential to reduce water shortages. Besides the recipient area, we also consider the protection of ecosystems at the donor area. 2026-01-22T23:27:36+01:00 https://doi.org/10.5194/adgeo-67-117-2026 <b>Towards fully coupled Thermo-Hydro-Mechanical-Chemical (THMC) modelling in advanced reservoir engineering: GOLEM-PHREEQC</b><br> Marco De Lucia, Samuele Frigo, Max Lübke, Mauro Cacace, Elena Petrova, Hannes Hofmann, Magdalena Scheck-Wenderoth, and Guido Blöcher<br> Adv. Geosci., 67, 117–127, https://doi.org/10.5194/adgeo-67-117-2026, 2026<br> We introduce a novel coupling of GOLEM, a thermal-hydraulic-mechanical simulator, with the PHREEQC geochemical solver. The code is validated via benchmarks against reference 1D models and its functionalities demonstrated on a 2D geochemical heterogeneous domain. This open-source  software enables the simulation of complex subsurface processes for the development of geothermal resources. 2026-01-05T23:27:36+01:00 https://doi.org/10.5194/adgeo-67-101-2025 <b>Storm Erwin: societal and energy impacts in northern Europe on 7–9 January 2005</b><br> Anthony J. Kettle<br> Adv. Geosci., 67, 101–116, https://doi.org/10.5194/adgeo-67-101-2025, 2025<br> On 7–9 January 2005 Storm Erwin passed across northern Europe, causing damage from Ireland to Russia, including power outages. Southern Sweden had the worst impacts with two nuclear stations shut-down and widespread destruction of transmission lines. For offshore wind energy in the North Sea, the storm was important to understand extreme environmental conditions for turbine operation. This work presents an analysis of North Sea tide gauge and wave data to assess extreme wave and surge levels. 2025-12-17T23:27:36+01:00 https://doi.org/10.5194/adgeo-67-91-2025 <b>Waiwera: evolving understanding for management of a New Zealand shallow and low enthalpy geothermal system</b><br> Michael Kühn, Graham Paul D. Viskovic, Tim Schöne, Melissa Präg, Charlotte Ribacki, Leonard Grabow, and Thomas Kempka<br> Adv. Geosci., 67, 91–100, https://doi.org/10.5194/adgeo-67-91-2025, 2025<br> Waiwera in New Zealand is a small coastal village with a geothermal reservoir underneath. Hydrogeological models support water management by providing insights into sustainable extraction from the system. It is artesian and the geothermal water is of meteoric origin percolating down to sufficient depth getting heated. It rises through a fault zone into the shallow and leaky aquifer. Most recently the springs have restarted discharging geothermal water on the beach. 2025-12-09T23:27:36+01:00 https://doi.org/10.5194/adgeo-67-79-2025 <b>Quantifying carbonate microstructure using classical segmentation pipelines for CCS and radioactive waste applications</b><br> Wurood S. Alwan, Omar Choudhry, Paul Glover, Louey Tliba, and Richard Collier<br> Adv. Geosci., 67, 79–89, https://doi.org/10.5194/adgeo-67-79-2025, 2025<br> We mapped pore networks in carbonate scanning-electron-microscope (SEM) images to aid safe CO2 storage and radioactive-waste isolation. An open 29 000 × 23 000-pixel mosaic was split into 100 fully hand-labelled tiles. Eight classic computer-vision pipelines were benchmarked: Watershed gave the best recall–precision balance, and a simple Hybrid-Voting of three filters halved false alarms. The data, masks and code offer an immediate reference set for training and testing future 3-D deep-learning models. 2025-12-03T23:27:36+01:00 https://doi.org/10.5194/adgeo-67-69-2025 <b>Characterization of the hydraulic properties of a planned High Temperature Aquifer Thermal Energy Storage (HT-ATES) system during well development</b><br> Cornelius O. Schwarze, Liang Pei, Lioba Virchow, Elena Petrova, Ben Norden, Simona Regenspurg, Katrin Kieling, Guido Blöcher, and Stefan Kranz<br> Adv. Geosci., 67, 69–78, https://doi.org/10.5194/adgeo-67-69-2025, 2025<br> To make better use of underground heat storage, we need to understand how water flows through deep rock layers. Normally, this is tested after drilling is finished, but we tried doing it during an earlier stage to save time and effort. At a site in Berlin, we tested a new way to measure how water moves through rock while the borehole was still being developed. The method worked well and gives quicker, reliable insights into underground conditions. 2025-11-28T23:27:37+01:00 https://doi.org/10.5194/adgeo-67-57-2025 <b>In-soil hydrogen concentration monitoring using MONHyTOR: application for natural hydrogen exploration</b><br> Niko Adjie, Clarisse Bordes, Daniel Brito, Djamel Nasri, and Éric Normandin<br> Adv. Geosci., 67, 57–67, https://doi.org/10.5194/adgeo-67-57-2025, 2025<br> In natural hydrogen exploration, locating deep gas seepage is often done by measuring soil gas content. For that purpose, we developed a long-term hydrogen concentration monitoring instrument named MONHyTOR. Our laboratory test demonstrates its accuracy, and field data indicate that hydrogen circulation in the soil depend on soil type, water circulation in the soil, air pressure, and air temperature. MONHyTOR can prove to be a promising tool in the natural hydrogen exploration scene. 2025-11-21T23:27:37+01:00 https://doi.org/10.5194/adgeo-67-45-2025 <b>Mapping Critical Raw Materials (CRM) hard rock deposits in Europe</b><br> Capucine Albert, Guillaume Bertrand, Hervé Berthier, Daniel P. S. de Oliveira, and Jørgen Tulstrup<br> Adv. Geosci., 67, 45–55, https://doi.org/10.5194/adgeo-67-45-2025, 2025<br> This article presents the map and dataset of critical raw materials (CRM) deposits in Europe produced within the GSEU (Geological Service for Europe) project. The map displays over 800 deposits in 33 countries. The article describes the methodology for compiling and harmonizing data, as well as a global assessment of CRM potential in Europe. It also discusses barriers of compiling and harmonizing CRM data at continental scale, and the limitations of the map and its dataset. 2025-11-17T23:27:37+01:00 https://doi.org/10.5194/adgeo-67-35-2025 <b>Effect of spatial variability on uranium diffusion in the three facies of the Opalinus Clay at Mont Terri</b><br> Marco De Lucia, Marco Fabbri, and Theresa Hennig<br> Adv. Geosci., 67, 35–44, https://doi.org/10.5194/adgeo-67-35-2025, 2025<br> The effect of spatial variability on uranium diffusion in Opalinus Clay over a million years was assessed by 2D reactive transport simulations. Different rock types and porosity impacted results, with variability's influence growing with longer correlation lengths of geostatistical simulations (up to 12.9 %). This highlights that 1D models may underestimate uncertainty in long-term radionuclide transport at repository sites, and spatial variability must be considered. 2025-10-30T23:27:37+01:00 https://doi.org/10.5194/adgeo-67-25-2025 <b>Database application for multi-level area-specific FEP catalogues in the German site selection process for high-level radioactive waste disposal</b><br> Paulina Müller, Eva-Maria Gottron, Yvonne Messerschmidt, Florian Schöne, Tobias Wengorsch, Anne Bartetzko, and Wolfram Rühaak<br> Adv. Geosci., 67, 25–33, https://doi.org/10.5194/adgeo-67-25-2025, 2025<br> The safe disposal of nuclear waste requires consideration of future developments in nature on the repository, like for instance glacifications. We show an approach by using a sophisticated database for a systematic consideration of such developments and their possible interactions. 2025-10-20T23:27:37+02:00 https://doi.org/10.5194/adgeo-67-15-2025 <b>Preliminary laboratory studies on hydrogen storage in a salt cavern of the Eocene Barbastro Formation, Southern Pyrenees, Spain</b><br> Timea Kovács, José Mediato, Berta Ordóñez, Nuria Garcia-Mancha, Pablo Santolaria, Pablo Calvín, José Sanchez Guzman, Jesús Gracia, Sara Roces, Pilar Mata Campos, and Edgar Berrezueta<br> Adv. Geosci., 67, 15–24, https://doi.org/10.5194/adgeo-67-15-2025, 2025<br> This study explores how rock salt reacts to hydrogen, aiming to support safe underground storage of renewable energy. Lab tests on samples from a potential salt cavern-type site in Spain showed that hydrogen caused no major changes to the rock. Minor effects were limited and did not impact overall stability. These findings help confirm that storing hydrogen in salt formations is a safe and reliable option for future energy systems. 2025-10-10T23:27:37+02:00 https://doi.org/10.5194/adgeo-67-5-2025 <b>Carbon dioxide and nuclear waste locked up for eternity at depth as a copy from nature</b><br> Michael Kühn<br> Adv. Geosci., 67, 5–14, https://doi.org/10.5194/adgeo-67-5-2025, 2025<br> The prevailing view in the scientific community is that large amounts of carbon dioxide (CO2) from the atmosphere and highly radioactive waste must be disposed of safely. In that regard, studies on natural processes that extend over thousands of years help to assess the long-term behaviour of deep geological repositories. From a purely scientific point of view, CO2 storage and final disposal of highly radioactive waste are feasible. 2025-09-16T23:27:37+02:00 https://doi.org/10.5194/adgeo-67-1-2025 <b>Preface to the special issue of the Division Energy, Resources, and the Environment at the EGU General Assembly 2025</b><br> Michael Kühn, Sonja Martens, Johannes Miocic, Viktor J.

Weydt, Thorsten Agemar, Michael Erb, Niklas Mantei, Nicole Dobrzinski, Josef Weber, Sebastian Sperlich, Jeroen van der Vaart, Kristian Bär, Inga Moeck, and Ingo Sass<br> Adv. Geosci., 65, 199–210, https://doi.org/10.5194/adgeo-65-199-2025, 2025<br> 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. 2025-03-24T23:27:37+01:00 https://doi.org/10.5194/adgeo-65-189-2025 <b>Porosity Estimation of the Permo-Triassic Sherwood Sandstone Group Using BNRM and Petrophysical Models</b><br> Sodiq Oguntade, Ulrich Ofterdinger, Jean-Christophe Comte, Ryan Gee, Myles Kynaston, and Robert Raine<br> Adv. Geosci., 65, 189–197, https://doi.org/10.5194/adgeo-65-189-2025, 2025<br> 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. 2025-03-18T23:27:37+01:00 https://doi.org/10.5194/adgeo-65-181-2025 <b>Challenges in experimental investigations of Paracoccus denitrificans activities in salt-bearing porous media</b><br> Jafar Qajar, Selen Ezgi Celik, Alejandra Reyes Amezaga, Sebastiaan Godts, Laurenz Schröer, Amir Raoof, and Veerle Cnudde<br> Adv. Geosci., 65, 181–187, https://doi.org/10.5194/adgeo-65-181-2025, 2025<br> 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. 2025-02-13T23:27:37+01:00 https://doi.org/10.5194/adgeo-65-171-2025 <b>The Horizon Europe AGEMERA Project: Innovative Non-Invasive Geophysical Methodologies for Mineral Exploration</b><br> Jari Joutsenvaara, Marko Holma, Pasi Kuusiniemi, Jarmo Korteniemi, Helena Seivane, David Marti-Linares, Martin Schimmel, Giulio Casini, Grant George Buffett, Markku Pirttijärvi, Ari Saartenoja, Barbara Štimac Tumara, and Ivan Kapustin<br> Adv.

Geosci., 65, 159–169, https://doi.org/10.5194/adgeo-65-159-2025, 2025<br> 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. 2025-01-29T23:27:37+01:00
