In this article, we will demonstrate the benefit of the electromechanical storage of energy over long operating cycles (with time constants ranging from several minutes to a few hours), within the scope of decentralized electrical energy production. Both the principle and technology of the primary components used in an electromechanical accumulator will be presented herein. A number of well-known examples of systems will be shown in order to derive a summary state-of-the-art. We will then proceed by providing the example of a prototype developed at the SATIE Laboratory in the aim of designing a stationary accumulator for a domestic application requiring power on the order of one kilowatt.
