Some storms have the potential to do great things. On December 1, 2016, for instance, a low-pressure zone called Theresa caused more than 31,000 megawatts of wind power to be temporarily fed into the grid throughout Germany – a tremendous surge of power compared to an average day. Unfortunately, however, much of that power was probably never used because of the absence of energy storage systems. .
But this frustrating picture is set to change. A new energy storage system called Future Energy Solution (FES) is being developed by Siemens in cooperation with Hamburg University of Technology and municipal utility company Hamburg Energie. The system, which is located in Hamburg and promises to store the excess power generated by wind parks for several hours or even a whole day, is being created as part of the Future Energy Systems project, which is funded by Germany’s Ministry for Economic Affairs. This approach is designed to help solve the problem of how the energy generated by wind turbines can be affordably stored when it’s not needed in the grid or cannot be transmitted because of potential overloads.
