This workshop was a collaborative event organised by GEOTHERMICA, IEA Geothermal and the Netherlands Enterprise Agency (RVO). It took place in Hoorn on the afternoon of 20 April 2023 and was sponsored by RVO, following a morning site visit to ECW’s Middenmeer High Temperature Aquifer Thermal Energy Storage project.

The event marked the first step in identifying needs for further development and international dialogue on Aquifer Thermal Energy Storage (ATES), a key component of the heating and cooling transition. It brought together ATES experts, public authorities, and interested stakeholders to share knowledge, compile completed and ongoing studies, define the scope of an ATES review, and spark ideas for future collaboration.

As part of the programme, participants visited ECW Energy, the largest geothermal operator in the Netherlands, and the GEOTHERMICA HEATSTORE high-temperature ATES demonstration project. The workshop summary, proceedings booklet, and presentations from the meeting are available here.
