On June 17–18 2025, Kalliopi Tzoufka participated in the seminar "Thermal Energy Storage in Aquifers" hosted by the Technische Universität Clausthal. The Seminar brought together the consortia of national research projects focused on subsurface thermal energy storage, supported by the Federal Ministry of Education and Research (BMBF). The event provided an effective platform for knowledge transfer and for the exchange of recent advancements on research in subsurface thermal energy storage across Germany.
As part of the SpeicherCity research project, Kalliopi's results on high-temperature heat storage in the Molasse Basin as well as the integration of thermal energy storage into a geothermal-powered energy network were presented.
