Analysis, Modelling and assessment if an intelligent and environmentally neutral geothermal long-term heat storage system

Work package: Modelling and Environmental Impacts

The IGLU project aims at the development of an environmentally neutral and economical solar collector supplied energy storage system in a modular construction for integration into heat supply-systems of new or already existing appartment or multi-family buildings as well as in industrial buildings. Main focus of the subproject „Modelling and Environmental Impacts“ is the development of a numerical coupled thermo-hydromechanical-chemical (THMC) model tool based on the open-source scientific code software OpenGeoSys for a simulation based design of the IGLU energy storage system. Numerical sensitivity analysis is used for an optimization of thermo-hydraulic material properties and geometries of the heat storage system with respect to efficiency and environmental impacts. The model also will be used for the dimensioning of the laboratory test facility as well as for the prognosis of possible impacts on the geochemical state of soil and groundwater in the vicinity of the storage system. Results of these studies will serve as a basis for the development of a guideline for environmental compatibility.
