Heat and Cold Storage (ATES)

Heat-Cold Storage (ATES) is an accessible and widely used form of geothermal energy to heat and cool buildings with groundwater.

How does ATES work?

For ATES, groundwater is pumped up from ground water reservoirs (aquifers). The water pumped up for Heat-Cold storage is pumped up from a depth of around 150 meters. With the help of a heat exchanger, the pumped groundwater water can be used for cooling in summer and for heating in winter.

The process for the construction of a thermal storage installation is as follows:   

  1. You contact us about your Heat-Cold Storage (ATES) location  
  2. We perform a QuickScan of the area in which we indicate the challenges and the geothermal potential of the area.   
  3. If the underground is suitable, we will ensure that the appropriate permits and, if applicable, subsidies are applied for.   
  4. We will steer the process until the green light is given for installing a possible ATES installation. The end result is a complete report with recommendations outlining everything you need to take advantage of the geothemal heat in your area.
