Energy storage is the capturing and holding of energy in reserve for later use. Energy storage solutions for electricity generation include pumped-hydro storage, batteries, flywheels, compressed-air energy storage, hydrogen storage and thermal energy storage components.
Thermal energy storage (TES) can be found at solar-thermal electric power plants that use concentrating solar power (CSP) systems. Such systems use concentrated sunlight to heat fluid, such as water or molten salt. While steam from the fluid can be used to produce electricity immediately, the fluid can also be stored in tanks for later use.
The so-called battery “charges” when power is used to pump water from a lower reservoir to a higher reservoir. The energy storage system “discharges” power when water, pulled by gravity, is released back to the lower-elevation reservoir and passes through a turbine along the way.
As the cost of solar and wind power has in many places dropped below fossil fuels, the need for cheap and abundant energy storage has become a key challenge for building an energy system that does not emit greenhouse gases or contribute to climate change.
Flow batteries and compressed air energy storage may provide storage for medium duration. Two forms of storage are suited for long-duration storage: green hydrogen, produced via electrolysis and thermal energy storage. Energy storage is one option to making grids more flexible.
Energy can also be stored by making fuels such as hydrogen, which can be burned when energy is most needed. Pumped hydroelectricity, the most common form of large-scale energy storage, uses excess energy to pump water uphill, then releases the water later to turn a turbine and make electricity.

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. En…
