Thermal Energy Storage – Feasibility study High Temperature-Aquifer Thermal Energy Storage (HT-ATES) bij AVR  in DUIVEN


To develop an initial design including a set of boundary conditions for the integration of HT-ATES with an existing district heating system and heat source. There is no existing legal framework for HT-ATES. Therefore competent authorities are willing to support the realization of a large demo project to develop regulatory guidelines to pave the way for future projects.

Thermal energy storage

Depending on the outcomes, this feasibility study can lead to a detailed engineering & design study and permit application (process) in order to realize a large-scale energy storage demonstration project to be integrated in the existing district heating system in the Arnhem region.


At two locations (Rozenburg and Duiven), AVR is supplying heat to local district heating networks. In order to optimize the mismatch between supply & demand of heat , AVR and TNO will investigate the feasibility of a large scale (~20MW), high temperature (>140OC) Aquifer Thermal Energy Storage (HT-ATES).
