In the Port of Hamburg, ballast stones with electrothermal energy storage systems can store renewable energy from wind or sun in the form of heat. The project, in which Siemens Gamesa and the Technical University of Hamburg, among others, have been involved since June 2019, is called ETES. ETES stands for Electro-Thermal Energy Storage and could be used in the future to become independent of weather conditions. This would make it possible to draw on the energy generated even when the sky is overcast or there is no wind.
