- Application of the Play-Based Exploration Pyramid Approach Adapted to Deep Geothermal Resource Mapping at the European Scale in the EU GSEU ProjectPublication . Herms, Ignasi; Caldera, N.; Arnó, Georgina; Canteli, P.; García-Crespo, J.; Carrión, E.; Ramalho, Elsa; Carvalho, João; Nádor, A.; Steiner, C.; Janku, L.; Koevoets, M. J.ABSTRACT: This work introduces version 1.0 of the Pan-European Atlas of Sustainable GeoEnergy Capacities (SGC), developed within the GSEU (Geological Service for Europe) project. The Atlas applies the Play-Based Exploration Pyramid (PBEP) approach to harmonize and standardize the assessment of deep geothermal resources across Europe. The methodology follows a multiscale structure—Levels 0 to 3—that refines geothermal understanding from regional geosystems to detailed local targets. Version 1.0 has been published in spring 2025 via the European Geological Data Infrastructure (EGDI) and includes Levels 0 and 1. Level 0 provides public data from boreholes and thermal springs, serving as the base for Level 1, which maps favorable areas for geothermal exploration using Geothermal Play Typing (GPT). The release includes a catalogue of near 400 factsheets describing each GPT unit, along with a metadata report. Future versions (2.0 in 2025 and 3.0 in 2026) will introduce deeper layers of detail. Level 2 will identify potential geothermal reservoirs using 1D stochastic estimations of geothermal and heat storage potential. Level 3 will compile existing 2D/3D maps and models for detailed local-scale reservoir assessments. Altogether, the Atlas supports Europe's energy transition by enhancing knowledge and visibility of its deep geothermal potential.
- Atlas Europeo de Potencial de Geoenergías Sostenibles: una prioridad del Servicio Geológico para Europa (GSEU) [Resumo]Publication . Canteli, P.; Herms, Ignasi; Ramalho, Elsa; Carvalho, João; Arnó, Georgina; Caldera, N.; García-Crespo, J.; Carrión, E.RESUMEN: El proyecto europeo GSEU (Servicio Geológico para Europa, 2022-2027) respalda la visión del Pacto Verde Europeo a través del conocimiento del subsuelo y en particular, de las materias primas, la energía, el agua y todas las áreas relacionadas. El objetivo último del proyecto es establecer las bases de un Servicio Geológico para Europa a través de 48 servicios geológicos nacionales y regionales de 35 países europeos – EuroGeoSurveys –, y demostrar la capacidad del mismo. Uno de los resultados de este ambicioso proyecto será el denominado “Atlas Europeo del potencial de geoenergías sostenibles”; es decir, se construirá, por primera vez, un atlas continuo a escala europea, que incluirá mapas, bases de datos del potencial evaluado para el almacenamiento geológico (CO2, H2 y CAES); para los recursos geotérmicos profundos y someros; y almacenamiento subterráneo de energía térmica (frío y calor).
- Deep geothermal resources in the Pan-European Atlas of Sustainable GeoEnergy Capacities (GSEU project): The Play-based Exploration Pyramid conceptPublication . Herms, Ignasi; Caldera, N.; Arnó, Georgina; Canteli, P.; García-Crespo, J.; Carrión, E.; Ramalho, Elsa; Carvalho, João; Nádor, A.; Steiner, C.; Janku, L.; Koevoets, M. J.ABSTRACT: This work introduces version 1.0 of the Pan-EU Atlas of Sustainable GeoEnergy Capacities (SGC), delivered by the GSEU (Geological Service for Europe) project. It details the methodology evolving from the Play-Based Exploration Pyramid (PBEP) concept into a practical approach for sharing harmonized knowledge about deep geothermal energy potential across Europe. This Atlas aims to deliver a standardized and generalized understanding of geothermal resources, emphasizing the potential in the framework of the Europe’s sustainable energy transition. The PBEP concept of the PanEU Atlas of SGC follows a multiscale geothermal exploration approach that systematically narrows focus from a geosystem to local scale, organizing technical and scientific data from broad, low-knowledge areas to highly detailed high-knowledge regions or local targets. It aims to ensure a refined understanding of geothermal plays, improving the identification of potential areas across Europe, spanning four levels (Level 0 to Level 3) and incorporating further refined knowledge in the assessment of geothermal resource. Levels 0 and 1 GIS datasets were published along spring 2025 in the European Geological Data Infrastructure (EGDI) as version 1.0 of the Atlas. Information available includes public data from boreholes and thermal springs (Level 0), which forms the basis for Level 1 - a harmonized map highlighting favourable prospecting areas for deep-origin geothermal resources, classified according to Geothermal Play Types (GPTs). This is accompanied by a catalogue of factsheets for each delineated GPTs across EU (~ 400 in total), summarizing the generalized findings along with a report on description and metadata. This scale-dependent process will continue in version 2 of the Atlas, with Level 2 focusing on identified potential geothermal reservoirs using 1D lumped stochastic estimations for geothermal resources and medium to high heat storage potential into deep aquifers. Finally, Level 3 will provide detailed local-scale evaluations of specific targets, compiling already existing maps and models containing spatial-distributed reservoir assessed information in 2D and/or 3D.
