Abstract
This work investigates the effects of a heat pump (HP) coupled with thermal energy storage (TES) in a
renewables-based district heating (DH) system. In the current energy transition, the gradual substitution
of traditional fossil-based heating plants with renewables-based generation systems requires the
introduction of elements (such as storage systems) that guarantee stability in the energy availability. In
DH grids, the high investment costs related to the construction of large-scale TES systems call for an
efficient operation. In this regard, the introduction of HP enables an increase of the effective TES
capacity thanks to the exploitation of the TES as a heat source when the direct use of the stored energy
is not anymore possible. This study investigates the influence of the HP integration on the TES
performance and the effects on the primary energy requirements 20 and CO2 emissions using a well-
established numerical TES model, which takes into account the heat transfer mechanisms within the
TES itself and between the TES and the surrounding ground.
