Title:
SYSTEM FOR STORING ENERGY BY MEANS OF COMPRESSED AIR
Document Type and Number:
WIPO Patent Application WO/2013/034284
Kind Code:
A8
Abstract:
System for storing energy by means of compressed air, wherein: - a storage volume takes in air under elevated pressure pH, - ambient air is compressed in order to store energy and brought into the storage volume, - for removal from storage, compressed air is taken out of the storage volume and discharged into the environment, outputting work, - a turbo machine (low-pressure turbo machine) - or a plurality of such machines - for alternate compression and expansion compresses ambient air to a mean pressure pM or expands it therefrom, - a machine (high-pressure machine) for alternate compression and expansion compresses ambient air from the mean pressure pM to the storage pressure pH or expands it therefrom, or a plurality of such machines fluidically connected in parallel perform this task, - these machines (low-pressure turbo machine and high-pressure turbo machine) are fluidically connected in series and mechanically coupled to a respective or common generator/motor (i.e. an electrical machine that operates selectively as a motor or a generator).
