What is geothermal storage? This is an earth boiler (storage) in which the obtained heat is stored in the earth where after this heat can be reclaimed, if necessary, from this earth storage. What geothermal storage systems do exist?
		Open (aquifer) system. With this system water heated by the collector is pumped straight into the ground. As a result the ground/groundwater is heated and a so-called “heat bubble” is created With a temperature of up to about 32°C (NT ± 20°C).
When needed the heat can be withdrawn from this “heat-bubble” by Circulating the groundwater through a heat exchanger. Closed (earth loop) system. In this system the transport medium, heated by the collector, is circulated, during which the heat is transferred to the adjacent storage medium (groundwater or ground). When needed this heat can be withdrawn by the same transport medium? This “earth loop” system is suitable for higher temperatures (up to 80ºC) then the “aquifer” System. There is a distinction between normal storage (up to a depth 50 metres), and deeper storage (over 50 metres up to 150 metres) How large and deep can this storage become? Geothermal storage /recycling. It can also be achieved by using heat pumps, but this will not always be necessary Geothermal storage/ recycling. Basically it can be applied to relatively small systems to very large systems.
