The concept of RemediATES


RemediATES (= Remediation combined with Aquifer Thermal Energy Storage) is the name given to the combination of sustainable Heat/Cold storage and biological groundwater treatment.

The scientific research of RemediATES started in 2010 by Tim Grotenhuis at Environmental Technology of Wageningen University within the Dutch project 'Meer met Bodemenergie'. This applied research project aimed at improvement of energy storage combined with the development of a better legislation and a better understanding of the microbiology in the subsurface by Deltares, If-Technology, Bioclear earth and Wageningen Universiteit.


In a more fundamental PhD research Tim Grotenhuis was the copromotor of Wijb Sommer en Zhuobiao Ni. This research about optimization of energy storage and the combination of ATES (Aquifer Thermal Energy Storage) with treatment of contaminated groundwater at Wageningen University was finalized in 2015.

Thereafter success full pilots were performed in Utrecht (NL) and close to Copenhagen (DK) within the European Climate-KIC project ‘Europe-wide Use of Sustainable Energy from aquifers’ (E-USE(aq)).

In 2020 presentations at several congresses were planned upon the results of the Danish RemediATES pilot Hammerbakken in Birkerød of the Capital region of Denmark close to Copenhagen.

Congresses & papers


In 2021 the results of the Danish pilot will be presented at three international congresses by Mette Christophersen (Head of Department, Rambøll Denmark).

In 2020 two papers were published on market opportunities of RemediATES and a life-cycle assessment (LCA). This last paper compares RemediATES to a traditional approach of groundwater remediation. The LCA study is the result of a cooperation with Zhuobiao Ni in the Centre of Excellence on contaminated soil remediation  (‘111 project’) at the School of Environmental Engineering of Sun Yat Sen University in Guangzhou (CN).

Tim Grotenhuis is co-author of these publications.

Stadswende and RemediATES


Stadswende supports municipalities with implementation of innovative technologies upon transition to sustainable cities. RemediATES is one of these innovative technologies. The power of RemediaATES is the production of sustainable energy together with the purification of contaminated groundwater.
