To achieve utility scale energy storage, the path requires scalability with multi-megawatt installations common. For flywheels, large arrays of units installed as an ‘energy storage farm’ will be commonplace. The hardware and software to manage and control multiple units have been developed.
Grid energy storage, also known as large-scale energy storage, are technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed.
Another electricity storage method is to compress and cool air, turning it into liquid air, which can be stored, and expanded when needed, turning a turbine, generating electricity. This is called liquid air energy storage (LAES). The air would be cooled to temperatures of −196 °C (−320.8 °F) to become liquid.
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.
Electricity storage is one of the three key ways to replace flexibility from fossil fuels in the grid. Other options are demand-side response, in which consumers change when they use electricity or how much they use. For instance, households may have cheaper night tariffs to encourage them to use electricity at night.
Any electrical power grid must match electricity production to consumption, both of which vary significantly over time. Energy derived from solar and wind sources varies with the weather on time scales ranging from less than a second to weeks or longer.
