GeoLaB – the URL for Geothermal Energy

GeoLaB (Geothermal Laboratory in the Crystalline Basement) constitutes a novel underground research infrastructure (URL), presently in its exploration and confirmation of site suitability phase, tailored to investigate coupled thermal, hydraulic, mechanical, and chemical (THMC) processes in fractured crystalline rock and advance understanding and implementation of Enhanced Geothermal Systems (EGS). Located in Germany, GeoLaB aims to bridge the gap between laboratory research and field-scale geothermal applications. This paper presents the scientific exploration progress, strategic development, and project management framework of GeoLaB. As a collaborative initiative between leading Helmholtz Centres and academic partners, GeoLaB represents a cornerstone for Europe’s sustainable heating transition and international geothermal innovation. Through its interdisciplinary approach and integration of digital technologies, the project will contribute to safer, more efficient geothermal development and fosters global partnerships to advance renewable energy science.
