However, this coupled supply suffers from a seasonal mismatch, with most space heating being required in winter, while DCs produce heat during the entire year. Aquifer thermal energy storage (ATES) systems are a cost-efficient way to overcome this mismatch and increase the utilisation of DC waste heat. In this study, we quantify the potential waste heat of 19 DCs in Germany, 13 of which are located in areas that are hydrogeologically suited for installing ATES systems. The waste heat of the DCs is quantified based on the installed cooling machines, which are detected on aerial images, their estimated cooling capacity and common DC cooling load factors. Considering typical heat recovery rates of ATES systems, the 13 DCs could supply 707 GWh<sub>th</sub> of heat. By comparing this amount of potential waste heat with local heating demands, supply areas are delineated, revealing a total of around 20,000 buildings that could be supplied. In Frankfurt, which has one of the largest accumulations of DCs in Europe, six identified DCs located in areas most suitable for ATES could supply 541 GWh<sub>th</sub>, which is equivalent to 13% of the city's residential and commercial heating demand. Considering all ten DCs in Frankfurt by placing the ATES systems in the most suitable areas, even 819 GWh<sub>th,</sub> equivalent to 20% of the area’s heating demand, could be achieved. This demonstrates the high potential of waste heat storage from DCs for urban areas with suitable subsurface for ATES systems and its importance for current and future municipal heat planning.</p></div>","PeriodicalId":48643,"journal":{"name":"Geothermal Energy","volume":"14 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40517-026-00383-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low-enthalpy geothermal systems for direct heat production are commonly developed in sedimentary aquifers with high matrix permeability. Although such geothermal systems are not often associated with induced seismicity, the potential occurrence of induced seismic events is of concern in geothermal resource development and requires improved seismic hazard assessment associated with geothermal operations. Mechanical Analysis of Complex Reservoir for Induced Seismicity (MACRIS) is applied to evaluate the sensitivity for fault reactivation and induced seismicity potential in three-dimensional clastic reservoir models representative of low-enthalpy geothermal exploitation in the Netherlands. The reservoir models are separated by a single fault causing both no and normal reservoir offset, and, unlike previous induced seismicity studies, incorporate the effects of reservoir throw and flow compartmentalization. Results show the potential for fault reactivation and induced seismicity to be (i) substantially impacted by the three-dimensional interaction of injected cold-water volume and its destabilizing effect on complex faults in sedimentary aquifers, and (ii) characterized by moderately low seismic magnitudes for the majority of predicted events. Where reservoir throw is shown to contribute to the fault reactivation and seismicity potential, fault-related reservoir flow compartmentalization has an opposite effect and is shown to reduce the potential of a sealing or bounding fault. Results confirm the findings from previous studies by showing (i) a predominant sensitivity of induced seismicity potential to the thermo-elastic reservoir parameters and injection temperature, and the in situ stress conditions and fault frictional properties affecting slip length and resulting magnitude estimate of the seismic event. In particular, results show the seismic hazard potential to significantly decrease in the case of reservoir creep or stable in situ stress conditions, and by limiting reservoir thermal drawdown.</p></div>","PeriodicalId":48643,"journal":{"name":"Geothermal Energy","volume":"14 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40517-026-00380-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147342816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, this study aims to provide an overview of the 3D thermal state of the urban subsurface of Berlin, Germany, with the goal of identifying groundwater and geothermal archetypes. Based on a detailed 3D geological model, covering an area of 118 km<sup>2</sup> and a depth of 250 m, block-divided (500 m × 500 m × 50 m), steady-state groundwater flow and heat transport models are created. These block models serve as a basis for identifying groundwater archetypes representing areas with similar hydrogeological and infrastructure conditions. The simulated, large-scale groundwater temperature patterns are generally in good agreement with interpolated temperatures from depth-oriented measurements. In addition, the block-scale models capture thermal hot spots and low spots that are not detected by interpolated maps. Using regression-based decision trees, 38 groundwater archetypes are identified for the shallow anthropogenically influenced layer of blocks and 21 archetypes at deeper layers (&gt; 50 m bgl). Heated basements and groundwater head difference are the most contributing features in differentiating archetypes for the shallow layer of the blocks, while lower temperature boundary dominates selection of archetypes in deeper layers. Similarity of large-scale groundwater temperature patterns across different numbers of selected archetypes shows the robustness of the approach. Using thermal and geological criteria, 10 of the identified archetypes are classified as geothermal archetypes that indicate suitable conditions for ground source heat pump systems.

Induced seismicity is of particular concern to citizens, and the perception of seismic risk plays an important role in the acceptability of geothermal projects. Starting point for our considerations is the DeepStor research infrastructure project and observations made within this research environment. We establish a conceptual framework for participatory monitoring of seismicity in geothermal projects and explore its possible influence on socio-psychological factors related to risk perception and technology acceptability and acceptance. The participatory monitoring is based on a citizen science approach in which citizens are invited to actively participate in seismic measurements around a geothermal project using plug-and-play seismometers. The potential individual, societal and scientific implications of this approach are analyzed by introducing established participatory and social scientific concepts within the geothermal context. Our conceptual analysis suggests that participatory monitoring could effectively address seismic risk perception and acceptability by enhancing transparency, providing non-experts with first-hand experiences, and fostering discussions and informed decision-making. From a technical perspective, implementing this approach to create dense seismic networks enhances the evidence base in research projects and supports more balanced risk management strategies. This article lays the conceptual groundwork for combining social scientific and geophysical approaches and recommends citizen science demonstration projects accompanied by social scientific research to evaluate this approach. As case example, the planned implementation of the participatory monitoring approach within the DeepStor project is presented. Our findings aim to contribute to the ongoing discourse on sustainable energy transition, risk management and governance, and the role of public participation in geothermal energy development.</p></div>","PeriodicalId":48643,"journal":{"name":"Geothermal Energy","volume":"14 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40517-026-00373-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147337707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
