The role of energy storage is to balance supply and demand across energy systems, enabling the storage of excess energy during low demand periods for use during high demand periods. It enhances the reliability and stability of energy systems, facilitates the integration of green energy sources, and improves overall energy management.
Once stored, the energy can then be released to power turbines and generators. There are a few different methods to create this type of storage. “In some cases, the air can be stored underwater, in what are basically underwater balloons,” says Carriveau.
Pumped-storage hydroelectric dams, rechargeable batteries, thermal storage, such as molten salts, which can store and release large amounts of heat energy efficiently, compressed air energy storage, flywheels, cryogenic systems, and superconducting magnetic coils are all examples of storage that produce electricity.
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.
For energy storage technologies to be used more widely by commercial and residential consumers, research should focus on making them more scalable and affordable. Energy storage is a crucial component of the global energy system, necessary for maintaining energy security and enabling a steadfast supply of energy.
It is important to compare the capacity, storage and discharge times, maximum number of cycles, energy density, and efficiency of each type of energy storage system while choosing for implementation of these technologies. SHS and LHS have the lowest energy storage capacities, while PHES has the largest.
