This section of the website aims to describe the processes involved with each of the different energy storage technologies, as well as provide some information about the “state-of-the-art”. The potential areas of application from each of the technologies are listed and the main advantages and disadvantages of each of the technologies are also briefly discussed.
Please click the links under the technology header in the menu above or alternatively links to the pages containing the information on each of the technologies can be found below.

The Figure below shows the power ranges (in MW) of many different energy storage technologies as well as the duration over which they can provide power (seconds to hours). Possible uses for EES technologies include reserve and response services, transmission and distribution grid support and bulk power management.
A really useful energy storage resource is the US DOE Energy Storage Database made by Sandia National Laboratories.
