Electrical Energy Storage: an introduction

Introduction. Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years.

Overview of current development in electrical energy storage ...

The electrical energy from wind power is used to heat a bulk storage material; the heat energy is recovered to produce water vapor which in turn drives a turbo-alternator to generate electricity. A detailed study of load shifting of nuclear power plants by using cryogenic energy storage technology was recently reported in [171] .
