The success of a high-temperature aquifer thermal energy storage (HT-ATES) system depends on many factors, such as heat demand and supply, economic feasibility, and of course the suitability of the subsurface. In the Dutch WINDOW project, a comprehensive overview of the subsurface HT-ATES potential was created. The HT-ATES potential was mapped for eight geological formations in the Netherlands at a depth between 50-500 mbgl (meter below ground level), based on a geological model and eight subsurface criteria including depth, thickness, and reservoir properties and legal criteria that are related to the fresh/saline interface and groundwater protection zones. A traffic light system was used to show potential barriers: no barriers (green), potential barriers (yellow) and one or more barriers (orange), resulting in qualitative potential maps for HT-ATES in the Netherlands. The maps show that the western part of the Netherlands is generally most favourable for HT-ATES, which is beneficial as this area also offers great potential for geothermal energy and it is as well the most densely populated area with high heat demand and existing heat networks. The study identified the need for improved subsurface characterization in large areas where geological data is lacking. It should be kept in mind that HT-ATES systems are highly location-specific, and since the maps show regional potential, a more detailed local investigation is always required. In follow-up studies, the maps will be improved with additional geological data and extended with geological data of other countries in Europe and combined with maps of heat demand and maps indicating the opportunities for sustainable energy sources, like geothermal energy, to find the best options for an integrated heat supply system for the built environment. Locations with the highest potential are those where surface and subsurface conditions and requirements match. The methodology has been set up in such a way that the maps can easily be updated when new input data becomes available. It can be applied to other countries to define their qualitative HT-ATES potential.
