3.2 Comparison of Electricity Storage Systems Costs by Cycle Duration. Figure 12.10 shows the range of electricity-shifting costs for a kilowatt-hour with the three most common electricity storage systems according to [ 58 ]: pumped-storage, battery power plants using lithium technology, and PtG using methane.

In a decoupled E-P type technology, energy and power can be scaled separately, such as pumped hydro, compressed air energy storage [98], flow batteries or flywheel energy storage [99]. These are storage technologies where the conversion from stored energy form to electrical output is performed by a dedicated device, e.g.,

Mechanical energy storage. The document discusses three types of mechanical energy storage: pumped hydroelectric storage (PHS), compressed air energy storage (CAES), and flywheels. PHS involves pumping water to a higher elevation and releasing it through turbines to generate power. CAES compresses air underground for
