Energy storage for electricity generation
Energy capacity —the total amount of energy that can be stored in or discharged from the storage system and is measured in units of watthours (kilowatthours [kWh], megawatthours [MWh], or

The economics of energy storage strictly depends on the reserve service requested, and several uncertainty factors affect the profitability of energy storage. Therefore, not every storage method is technically and economically suitable for the storage of several MWh, and the optimal size of the energy storage is market and location dependent. Moreover, ESS are affected by several risks, e.g.:
Electrochemical: Storage of electricity in batteries or supercapacitors utilizing various materials for anode, cathode, electrode and electrolyte. Mechanical: Direct storage of potential or kinetic energy.
Global capability was around 8 500 GWh in 2020, accounting for over 90% of total global electricity storage. The world''s largest capacity is found in the United States. The majority of plants in operation
