Abstract: This study presents an experimental study into the seasonal cycles of an underground thermal energy storage (TES) system used for heating an energy efficient house. The analysis is based on two years of continuous measurements from the experiment.
Seasonal underground storage systems are by no means a new subject. Some previous studies incorporating numerical simulations include the works of Nordel and Hellström , demonstrating a reliable large-scale solar heating system with seasonal storage.
The optimal design of MES with seasonal energy storage is a complex optimization problem due to the types of technology involved and their nonlinear behavior, and to the time variability of the input data.
In line with the goals of the paper, the MES is simplified to a single node with aggregated energy production, storage and consumption, and is therefore not representative of a full power system, e.g. at national or European scale. The analysis of underground H 2 storage in such power system is beyond the scope of this work.
