Charging Up: The State of Utility-Scale Electricity Storage in the
This report explores how economic forces, public policy, and market design have shaped the development of stand-alone grid-scale storage in the United States.
Grid energy storage
Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in batteries, and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around the Alps in Italy, Austria, and Switzerland. The technique rapidly expanded during the 196
