Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the
Depending on cost and other variables, deployment could total as much as 680 gigawatts by 2050. "These are game-changing numbers," Frazier said. "Today we have 23 gigawatts of storage capacity, all of which is pumped-hydro.". Initially, the new storage deployment is mostly shorter duration (up to 4 hours) and then progresses to longer
Singapore''s First Utility-scale Energy Storage System. Through a partnership between EMA and SP Group, Singapore deployed its first utility-scale ESS at a substation in Oct 2020. It has a capacity of 2.4 megawatts (MW)/2.4 megawatt-hour (MWh), which is equivalent to powering more than 200 four-room HDB households a day.

The levelized cost of storing electricity depends highly on storage type and purpose; as subsecond-scale frequency regulation, minute/hour-scale peaker plants, or day/week-scale season storage. Using battery storage is said to have a levelized cost of $120 to $170 per MWh. This compares with open cycle gas turbines which, as of 2020, have a cost of around $151–198 per MWh.
