Abstract

The invention relates to a scalable device for storing and releasing energy, consisting of a housing that can be evacuated, a vacuum (12), at least one flywheel mass (2) on a shaft (17), at least one passive superconducting radial bearing and an electrical machine (24) that constitutes both a motor and a generator, wherein a cold surface is arranged in the vacuum container (11) for stabilizing the vacuum (12). The invention has the advantage that an energy store is provided that operates efficiently and cost-effectively with minimized energy losses, is scalable and also has sufficient safety elements to enable it to be used in industrial environments.
