Development and testing of a novel offshore pumped storage concept for storing energy at sea − Stensea

Abstract The paper presents the interim results of the StEnSea project, which comprises the development and testing of a novel pumped hydro storage concept for storing large amounts of electrical energy offshore. The following paragraphs introduce into the general description of the concept and give an overview of possible installation sites for full-scale commercial systems. Additionally, the building and further preparations of the prototype testing of a 1:10 scale model are described.
