One of the most significant issues related to electricity, is its storage. The question becomes even more complicated when it comes to renewable sources of its production, as their reliability depends on the weather. Belgian wind farms sometimes produce so much energy that it amounts exceed current needs. That is why now is the actual solution to the storage of the extracted resource.
In Belgium, see the solution to create an artificial island in the North Sea, where you can store the extracted wind energy. The island will have a form of "donut", which is located inside the hollow and filled with water. With the surplus of energy from windmills pumped water will be out of the cavity and pass back through the pipe connected to the cumulative turbines, which will act as energoskladov.
Thus, unclaimed at the moment the energy can be used later, the country is close to the point where it will be possible to completely abandon nuclear power. So far, unfortunately, the closure of the local nuclear power plant had to be postponed. But the Belgians are confident that they can extract from their North Sea wind farms 2,300 megawatts, which will replace part of the work in one of two nuclear reactors with a capacity of 3 thousand megawatts each.
Island storage will pour out of the sand, 3 km from the coast near the town of Belgium Wenduine. On the construction of the project could take up to five years.
