Read about other emerging technologies in the long duration storage market. The technology has evolved and improved over time as reversible hydroelectric turbines have developed and been improved such that the turbines could operate as both electricity generators as well as electric motor driven pumps. The first use of pumped storage in the United States was in 1930 using a large reservoir located near New Milford, Connecticut.
The first use of pumped storage was in 1907 in Switzerland.

Water is pumped from the lower reservoir(s) to higher reservoir(s) during times of inexpensive electricity and then allowed to fall, spinning a turbine or series of turbines, when the cost of electricity is high. Pumped-storage hydroelectricity, or pumped hydroelectric energy storage, stores energy in the form of the gravitational potential energy of water pumped from a lower elevation reservoir to a higher elevation. These systems provide highly-scalable and long-duration solutions. Liquid air storage shares many attractive characteristics with pumped hydro, and can provide similar grid services without the geographic constraints inherent in pumped hydro applications. Instead of storing energy electrochemically, like a battery, this technology stores energy as liquid air, which is comprised mostly of nitrogen, like the earth’s atmosphere. The most common occurrence of this technology is liquid air energy storage or cryogenic energy storage. This emerging technology captures heat and/or cold air to create energy on-demand or offset energy needs. Thermal storage is a promising new long-duration energy storage technology with many uses, similar to pumped hydro. While lithium-ion batteries supply 99 percent of new storage capacity today, they offer relatively short durations for storage (generally up to 4 hours), and can get very expensive if the required discharge duration is stretched to many hours. Companies then developed larger cells for use in electric vehicles, since then they have been widely deployed as grid-scale energy-storage applications.
They were first used in electronics, like a home laptop or a cell phone. Lithium-ion batteries were first developed in the 1970s and became commercially viable in the 1990s. Batteries are electrochemical storage solutions, which include advanced chemistry batteries, flow batteries, and capacitors. One of the fastest-growing segments of the energy storage market is lithium-ion batteries. Grid-scale energy storage utilizes a wide variety of technologies that address different applications. We are well-versed in a variety of energy storage products for a wide range of applications, based on location and the required duration for which the energy needs to be stored. Renewable energy, like all energy, is variable - so pairing solar and wind systems with energy storage adds additional resilience to your energy system. It is then converted back to electrical energy and deployed for use.Įnergy storage has a critical role to play in the transition to a 100% clean energy future. Storage can be performed in different ways and for varying amounts of time. Powering the Grid of the Future with Energy Storage What is energy storage?Įnergy storage systems convert electrical energy from a power network into a form in which it can be stored.
