The U.S. Department of Energy (DOE) today announced that its international energy storage database (www.energystorageexchange.org) has surpassed 420 documented energy storage projects from around the world. The database, the first of its kind, provides free, up-to-date information on grid-connected energy storage projects and relevant state and federal policies. It is funded through DOE's Sandia National Laboratories, and has been operating since January 2012.
The Energy Storage Database lists 420 energy storage projects from 34 countries with a combined 123GW of installed capacity. 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 of the database shows 18 federal and state policies addressing grid connected energy storage, from rules and regulations to tariffs and other financial incentives.
Anybody can create an account and add projects, and each project goes through a vetting process where database staff contact the project owner to verify data accuracy.
