ATES workshop 2023

Aquifer Thermal Energy Storage workshop

20-21 April 2023 Hoorn, The Netherlands

IEA TCP Geothermal and GEOTHERMICA organised a workshop on the need of Aquifer Thermal Energy Storage (ATES) to be an essential part of the Heating and Cooling transition. The workshop aimed to connect ATES experts and public/national authorities, compiling relevant finished & ongoing studies, outlining an ATES review study, and creating ideas for further collaboration.  In addition, the workshop included a site visit to ECW Energy, the largest Geothermal operator in the Netherlands, and a visit to the GEOTHERMICA HEATSTORE High-Temperature ATES Demonstration project.

The workshop was a hub for ATES experts and public & national authorities, facilitating networking and knowledge sharing. It provided a unique opportunity to bring minds together to discuss the future of sustainable energy solutions.

Participants compiled a wealth of completed and ongoing studies on ATES, providing a comprehensive understanding of its potential and impact. An ATES review study was outlined, setting the stage for further research and development in this area.

A highlight of the event was the opportunity for attendees to visit ECW Energy, the largest geothermal operator in the Netherlands. It was an eye-opening experience to witness real-world ATES applications. Additionally, a visit to the GEOTHERMICA co-funded project HEATSTORE High-Temperature ATES Demonstration showcased innovation in action.

The workshop was a resounding success, with nearly 30 passionate participants fostering the exchange of knowledge, ideas, and experiences across various sectors. ATES stands as a cornerstone of the sustainable future.
