Info

In the development process of wind energy Zaanstad cooperates with local companies and customers. The Zaanse Energy Cooperation is a collaboration between Zaanstad and local inhabitants for the realization of a 3 MW wind turbine in the region Seandelft. Besides this, research is going on about possible collaborations with companies in other regions in Zaanstad. Figure 4. Potential locations for the implementation of wind turbines in Zaanstad [3] 14
3.6 GEOTHERMAL ENERGY Geothermal energy is thermal energy stored in the Earth. There are two main types of applications for geothermal energy: shallow and deep. The shallow applications can be separated in borehole thermal energy storage (BTES) and aquifer thermal energy storage (ATES). These types are already applied at many locations in the Netherlands. Deeper applications of geothermal energy are used for heat extraction from a depth of 1 km and deeper. Shallow applications Aquifer thermal energy storage (ATES) This is a seasonal type of storage. ATES is an open system, since the heat or cold is stored in a sand layer (aquifer) between other watertight layers. The most used ATES is the storage doublet system, which consist of a cold and hot source. The heat is extracted in the winter and used for heating in the building. The heat is extracted with a ground source heat pump. This heat pump uses electricity to transfer heat in an efficient way. Figure 6. Schematic overview of shallow applications of geothermal energy; BTES (left) and an ATES system (right) Borehole thermal energy storage (BTES) The closed variant of the shallow geothermal energy is called a borehole thermal energy storage system (BTES). The BTES consists of several tubes which are placed in the underground. Through these tubes runs water and the water absorbers the heat or cold from the ground. This system is most suitable when there are no aquifers available or drilling is too expensive. Deep geothermal energy production Deep geothermal energy means extracting heat from the earth from a depth of 1 km and deeper. The energy is extracted through a heat exchanger and used for spatial heating or greenhouse heating. TNO has developed software - ThermoGISTM – which can be used to locate potential spots for deep geothermal energy. The potential recoverable heat (PRH) for spatial heating in the Netherlands is estimated at 12 EJ. The software can be used to calculate the temperature of the potential energy at 2 km and 5 km.
