ENERGY STORAGE METHOD AND SYSTEM FOR STORING ENERGY

摘要

The invention describes an energy-storage system which is based on the phenomenon of sorption/desorption of a vapour in a sorbent, and includes: a) a first thermally insulated tank (2) which houses a sorbent having an affinity for a vapour; b) a second thermally insulated tank (3) which also houses a sorbent having an affinity for said vapour; c) a compressor device (4) connected between the first tank (2) and the second tank (3) in order to compress the vapour by making same pass from the first tank (2) to the second tank (3) in an energy-accumulation phase; and d) an expander device (5) connected between the first tank (2) and the second tank (3) in order to expand the vapour, enabling same to return from the second tank (3) to the first tank (2) in an energy-depletion phase.
