Cement cone for "Stored Energy in the Sea"
How can energy be stored in the future near offshore wind farms? To this end, researchers at the Fraunhofer Institute for Wind Energy and Energy System Technology have developed a new storage system based on hollow cones on the floor of the sea. The principle is similar to that employed in conventional pumped-storage power plants. A cement prototype three meters high was tested in Lake Constance at the end of 2016. The test produced very promising results. The team of researchers is now planning to explore suitable sites for a demonstration project in Europe in more detail.
There is major potential for the use of sea pumped-storage plants at locations near coastlines, in particular coasts of regions with high population densities like in the Norwegian Trench. The greatest potential is exhibited by the EU, followed by the USA and Japan.
