ATES is much less visible than other sources of sustainable energy and it is therefore often overlooked. The installation of 50,000 systems in Europe, which should be achievable in the next decade, could reduce annual CO2 emissions by approximately 3 million tons. Even that electricity can be produced sustainably.

The system involves the creation of both a warm and a cold groundwater reservoir, enhancing efficiency.The resulting cold is stored separately in the winter so that it can be used effectively again in the summer, and so on.The water cools down as it releases heat. The heated groundwater can be used in the winter to heat buildings.Cooling buildings with a climate control system (air conditioning) produces heat that can be stored (using a heat exchanger) in an aquifer instead of being released to the atmosphere as with conventional air-conditioning systems the soil isolates the stored energy like a thermos flask.Deltares is working on this project with a consortium of eight project partners and several other parties in Europe. It includes six pilot projects in five countries that will generate a flywheel effect for the introduction of ATES systems throughout Europe. The Climate-KIC project ‘Europe-wide Use of Sustainable Energy from aquifers’ – E-USE(aq) – is demonstrating how ATES systems can be implemented in several countries. ATES is a simple way of meeting that demand by using the soil. Global demand for heating and cooling in the built environment accounts for about 40% of total primary energy consumption. Aquifer Thermal Energy Storage (ATES) is a smart way to re-use heat and cold in buildings and it is widely recognised as promising technology for sustainable energy. Our soils can provide sustainable energy.
