Energy storage technologies could be classified using different aspects, such as the technical approach they take for storing energy; the types of energy they receive, store, and produce; the timescales they are best suitable for; and the capacity of storage. 1.
This is the most traditional and also most commonly used (when talking globally) method of energy storage, in which the mechanism of storage is creating hydraulic height (mainly water) using pumps (i.e., pumping water from a reservoir at a lower altitude to a higher reservoir) during the charging phase.
2. Regarding the type of energy to be stored (received by the storage system) and produced (the output of the system), any energy carrier (electricity, mechanical work of shaft or reciprocating pistons, thermal energy, fuels, etc.) could be the case.
Energy storage technologies could be classified using different aspects, such as the technical approach they take for storing energy; the types of energy they receive, store, and produce; the timescales they are best suitable for; and the capacity of storage. 1.
In the discharging phase, the cycle gets the opposite of the charging phase and acts just like a closed Brayton cycle. High-pressure high-temperature gas/air goes through the expander, cold low-pressure gas goes through the cold thermal energy storage, warms the storage unit up, and gets colder itself.
Thermochemical thermal energy storage could be a potential solution for some sorts of specific applications due to its high energy storage density even compared to the latent storage method, long possible time of storage, and low rate of losses, though this method is currently too expensive and under development.
Depending on whether electricity is stored in the former (electrostatic) or latter (magnetic) field, electrical energy storage systems will comprise capacitors (and supercapacitors in higher capacity) or superconducting magnetic energy storage systems, respectively.
