Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
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

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. En
