Thermal deformation in High Temperature ATES systems

Abstract

High Temperature Aquifer Thermal Energy Storage (HT-ATES) is a technique for storing large amounts of residual heat in the subsurface. In this report, the thermal deformation resulting from the temperature change in the subsurface is investigated and the resulting risks for buildings are assessed. To do this a case study is done on the TU Delft campus subsurface. It has been determined that the thermal deformation due to HT-ATES systems is small with a maximal deformation of 14 cm. It has also been determined that the stability risks for buildings that are constructed in the vicinity of a HT-ATES system are very low.
