Aquifer Thermal Energy Storage in the Netherlands: A Review

With the worlds energy problems still far from being solved, it is commonly agreed upon, that storing energy is a vital part of any possible solution. When discussing the storage, the type of energies must be distinguished. The storage of thermal energy can be accomplished by several means. One of this means is the storing of the thermal energy in naturally occurring water-bearing underground layers, so called aquifers. While this technique is in practice for several years now, it is also still undergoing a lot of research and development. Therefore, it is a good idea to look at countries, that already have experience with these storing systems. This paper looks at the status quo of the thermal energy storage in the Netherlands and the part that aquifer storage plays in them while also taking a closer look at distinct projects that are already completed or in development. The Netherlands provide a very interesting case for several reasons. The geological conditions provide very good situation for shallow geothermal storage, but over the last years deep geothermal storage is on the rise, too. And the government is willing to take full advantage of the possibilities provided in the country. A closer look at the situation can provide a lot of insight for upcoming projects.
