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 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.
Here, we project future prices for 11 electrical energy storage technologies. We find that, regardless of technology, capital costs are on a trajectory towards US$340 ± 60 kWh−1 for installed stationary systems and US$175 ± 25 kWh−1 for battery packs once 1 TWh of capacity is installed for each technology.
The paper discusses the concept of energy storage, the different technologies for the storage of energy with more emphasis on the storage of secondary forms of energy (electricity and heat) as well as a detailed analysis of various energy storage projects all over the world.
6.8 GW of energy storage globally (Figure ES8). Thermal energy storage applications, at present, are dominated by CSP plants, with the storage enabling them to dispatch electricity into the evening or around the clock.

To give some context to these volumes, the current energy storage capacity of pumped hydro storage, as of 2017, sum up to 4.5 TWh worldwide (IRENA 2017). However, it is important to highlight that batteries and pumped storage are not in competition but rather provide complementary services, since electric batteries will mostly be used for short-term services (up …
