With growing demand for electricity storage from stationary and mobile applications, the total stock of electricity storage capacity in energy terms will need to grow from an estimated 4.67 terawatt-hours (TWh) in 2017 to 11.89-15.72 TWh (155-227% higher than in 2017) if the share of renewable energy in the energy system is to be doubled by 2030.
Today, an estimated 4.67 TWh of electricity storage exists. This number remains highly uncertain, however, given the lack of comprehensive statistics for renewable energy storage capacity in energy rather than power terms.

With energy storage, there are energy losses due to the round-trip efficiency which contributes to the loss of revenue [ 31, 77 ]. The LCOE for GIES is higher than non-GIES. This is due to a lower efficiency (i.e. energy output) for thermal energy storage, although the capital cost is lower.
Energy storage is costly and, with these market conditions, generation alone without energy storage is the most profitable. With energy storage, there are energy losses due to the round-trip efficiency which contributes to the loss of revenue [ 31, 77 ]. The LCOE for GIES is higher than non-GIES.
