The Geothermie Symposium 2025, one of Austria’s key annual events dedicated to geothermal energy and sustainable heating systems, took place 5–7 November 2025 in Austria. Organized by Verein Geothermie Österreich, the symposium brought together experts, industry representatives, researchers, and policymakers to discuss innovations supporting the transition toward low-carbon heating and cooling solutions
INTERSTORES Research Presented
The INTERSTORES project was presented during the symposium by Abdulrahman Dahash from AIT Austrian Institute of Technology. His presentation, titled “INTERSTORES: Towards demonstration of underground thermal energy storage in future district heating systems,” highlighted the project’s latest progress in developing and demonstrating seasonal thermal energy storage (sTES) solutions across Europe. The presentation focused on how underground thermal energy storage technologies can support the decarbonisation of district heating networks, enabling more efficient integration of renewable energy sources and improving energy system flexibility.
Engaging the Geothermal Community
The event provided an important platform for connecting with national stakeholders involved in geothermal energy development and sustainable heat supply. The audience included representatives from the scientific community, industry, civil society, and public authorities, all of whom play an important role in advancing innovative subsurface energy solutions.
During the event, INTERSTORES was presented through the project talk and supporting materials, including project leaflets distributed to participants, enabling direct engagement with professionals interested in geothermal and thermal storage technologies.
Supporting the Future of Sustainable Heat
Participation in Geothermie Symposium 2025 allowed INTERSTORES to strengthen its visibility among geothermal developers, energy utilities, research institutes, and policy stakeholders. These connections are essential for supporting the future replication and upscaling of seasonal thermal energy storage solutions within European heating systems.
Events like this play a key role in ensuring that the innovations developed within INTERSTORES contribute to the broader goal of sustainable, resilient, and decarbonised energy systems across Europe.
