Energy Storage for Wind-Generator Application

摘要

A low-cost method was developed for storing energy and stiffening power supplied by wind generators. It involved inflatable, fabric-reinforced elastic liners buried underground and containing a fluid, probably water, at an intermediate pressure. The ground would be subject to elastic deformation and the method could be applicable to unstable ground such as deep sand, heterogeneous sedimentary or other unconsolidated deposits in remote locations or hostile environments. While the density of energy storage was considered low, compared with pumped-hydro systems, the technology could be attractive for developing countries.
