International Innovation Network for the Development of Cost- and Environmentally Efficient Seasonal Thermal Energy Storages (INTERSTORES)

Project research area
Energy Transition​
Project duration
01.01.2024 - 31.12.2027


INTERSTORES is a consortium of 14 partners led by Martin Luther University Halle-Wittenberg, Germany, aiming at significantly improving feasibility of large-scale thermal energy storage in a 4-year EU Horizon Innovation Action project. Two different type of full-scale demonstration cases are at the heart of the project: one in Germany and one in Finland.

GTK shall provide insight into the significance of structural geology in CTES (Cavern Thermal Energy Storage) projects and create guidelines for future CTES projects to take geology appropriately into account. GTK shall study the bedrock behavior around CTES through modelling and field measurements, conduct scenario studies in different geological settings to reveal concept transferability, and address legal and environmental aspects of CTES projects to contribute to market potential assessment of high temperature CTES.
