Heat and Cold Storage (ATES)

Heat and Cold Storage (ATES) is an accessible and widely applied technique for heating and cooling buildings with groud water. With the help of a heat exchanger, the pumped groundwater can be used for cooling buildings in summer and heating in winter.

For both ATES and geothermal energy, groundwater is pumped up from aquifers. For ATES, the maximum depth of the aquifer is around 150 meters. For generating geothermal energy the water is pumped up from reservoirs at a depth of 1.5 to 4 kilometers. From 4 kilometers on we speak of ultra-deep geothermal energy (UDG).

Feasibility study

T&A offers a short feasibility study to find out all the necessary information about the subsurface, enabling our clients to assess whether the subsurface is suitable for the application of Heat and Cold Storage.

Permits and Grants

For ATES groundwater is extracted, therefore, a water permit is often required. In some cases, an omgevingsvergunning beperkte milieutoets (OBM) is also required.

There are no government granst that cover the entire process for the construction of a ATES system, but it is possible to receive subsidies for various parts of the system, such as the heat pump. In most cases the investment subsidy for renewable energy (ISDE) is available.T&A Survey will take care of te application for the necessary permits and subsidies for your project.
