In electric energy systems based on renewable generation plants supply and demand often do not occur in the same time. Consequently energy flexibilization is gaining importance in industrial environments, whereby decentralized automation offers opportunities. Compressed-air systems on industrial plants supply manufacturing equipment with compressed air, nitrogen and other technical gases, which partly can be obtained from air by deposition processes. Those systems consist of air compressors, gas separators, reservoirs and lines. With suitable dimensioning and by equipping with automation technology those product-service systems can be used for energy flexibilization purpose.
