Tarragona's subsoil holds deep geothermal energy potential, with temperatures reaching 70 to 90 degrees Celsius at depths greater than 100 metres, according to Dr Ignasi Herms, head of geological resources at the Cartographic and Geological Institute of Catalonia (ICGC). This discovery presents an opportunity for industrial applications in the region.
Dr Herms noted that similar conditions are found in the Penedès area. Both locations are significant conurbations with industrial zones that could use this energy source, he told reporters. The findings suggest a viable, deeper form of geothermal energy, distinct from more common surface geothermal exploitation.
Industrial Applications and Regional Benefits
The temperatures identified are particularly suitable for industrial processes, which often require consistent heat sources. Using geothermal energy could help local industries reduce their reliance on fossil fuels, potentially lowering operational costs and carbon emissions. This aligns with broader efforts to transition towards renewable energy sources across Catalonia.
While surface geothermal energy is already viable in many areas, the deep geothermal potential in Tarragona and Penedès offers a new avenue for energy independence. The ICGC's ongoing studies aim to map these resources more precisely, providing data for future energy projects. The institute's work is critical for understanding Catalonia's geological assets and their potential contribution to the region's energy mix.
Moving forward, further detailed geological surveys and feasibility studies will be necessary to determine the exact scale of the resource and the infrastructure required for its extraction and use. These steps will involve collaboration between geological experts, energy companies, and local authorities to develop sustainable energy solutions for Tarragona and the Penedès region.
