More than 420 energy storage projects worldwide with a total installed capacity of 123 GW are now listed on the U.S. Department of Energy’s energy storage database, Dr. Imre Gyuk, DOE's Energy Storage Program manager, has announced.

The projects cover 34 countries, with the continental breakdown shown in the figure – and more than half of them in North America (with California leading the states with 44 projects).

More than 50 energy storage technologies are represented worldwide, including multiple battery technologies, compressed air energy storage, flywheels, gravel energy storage, hydrogen energy storage, pumped hydroelectric, superconducting magnetic energy storage, and thermal energy storage.

The policy section also shows 18 federal and state policies addressing grid connected energy storage, from rules and regulations to tariffs and other financial incentives.

“This database shows the impressive diversity of energy storage projects across the globe, as well as the broad services they provide,” commented Gyuk, who is project manager of the database with Georgianne Huff of Sandia National Laboratories.

The database, the first of its kind, has been operating since January 2012. Projects for inclusion are invited.
