An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
The technologies that are most suitable for grid-scale electricity storage are in the top right corner, with high powers and discharge times of hours or days (but not weeks or months). These are Pumped Hydropower, Hydrogen, Compressed air and Cryogenic Energy Storage (also known as ‘Liquid Air Energy Storage’ (LAES)).
No matter how much generating capacity is installed, there will be times when wind and solar cannot meet all demand, and large-scale storage will be needed. Historical weather records indicate that it will be necessary to store large amounts of energy (some 1000 times that provided by pumped hydro) for many years.
8.1. Introduction Grid-scale energy storage has the potential to transform the electric grid to a flexible adaptive system that can easily accommodate intermittent and variable renewable energy, and bank and redistribute energy from both stationary power plants and from electric vehicles (EVs).
Hydrogen, Cryogenic (Liquid Air) and Compressed Air can all be built to scales near that of Pumped Hydro. Pumped Hydroelectricity is the incumbent standard for grid-scale electricity storage. It can store and generate electricity at high powers, with large storage capacities/discharge times.
There are many applications for electricity storage: from rechargeable batteries in small appliances to large hydroelectric dams, used for grid-scale electricity storage. They differ in the amount of energy that has to be stored and the rate (power) at which it has to be transferred in and out of the storage system.
