In general terms, Compressed air energy storage (CAES) is very similar to pumped hydro in terms of the large-scale applications, as well as the capacity of both in terms of output and storage. However, instead of pumping water from the lower reservoir to the higher reservoir as in the case with pumped hydro, CAES compresses ambient air in …

Other Ideas. Briefly, two other potential ways to store energy on a large scale are flywheels and a smart grid. The concept behind flywheels is fairly simple in that it is just the conversion of electrical energy to rotational kinetic energy for storage and then conversion back to electrical energy using a generator for extraction.
