Energy storage is the capturing and holding of energy in reserve for later use. Energy storage solutions for electricity generation include pumped-hydro storage, batteries, flywheels, compressed-air energy storage, hydrogen storage and thermal energy storage components. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources. . Grid energy storage is vital for preventing blackouts, managing peak demand times and incorporating more renewable energy sources like wind and solar into the grid. 1 Batteries are one of the most common forms of electrical energy storage. The first battery, Volta's cell, was developed in 1800.
