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.
Flywheels and Compressed Air Energy Storage also make up a large part of the market. The largest country share of capacity (excluding pumped hydro) is in the United States (33%), followed by Spain and Germany. The United Kingdom and South Africa round out the top five countries.

The DOE data is current as of February 2020 (Sandia 2020). 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%).
Global capability was around 8 500 GWh in 2020, accounting for over 90% of total global electricity storage. The world’s largest capacity is found in the United States. The majority of plants in operation today are used to provide daily balancing. Grid-scale batteries are catching up, however.
Europe and China are leading the installation of new pumped storage capacity – fuelled by the motion of water. Batteries are now being built at grid-scale in countries including the US, Australia and Germany. Thermal energy storage is predicted to triple in size by 2030. Mechanical energy storage harnesses motion or gravity to store electricity.
Other storage technologies include compressed air and gravity storage, but they play a comparatively small role in current power systems. Additionally, hydrogen – which is detailed separately – is an emerging technology that has potential for the seasonal storage of renewable energy.

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible. . Goals that aim for zero emissions are more complex and expensive than NetZero goals that use negative emissions technologies to achieve a. . The need to co-optimize storage with other elements of the electricity system, coupled with uncertain climate change impacts on demand and supply, necessitate advances in analytical tools to reliably and efficiently plan, operate, and. . The intermittency of wind and solar generation and the goal of decarbonizing other sectors through electrification increase the benefit of. . Lithium-ion batteries are being widely deployed in vehicles, consumer electronics, and more recently, in electricity storage. [pdf]
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
Other storage technologies include compressed air and gravity storage, but they play a comparatively small role in current power systems. Additionally, hydrogen – which is detailed separately – is an emerging technology that has potential for the seasonal storage of renewable energy.
In a new paper published in Nature Energy, Sepulveda, Mallapragada, and colleagues from MIT and Princeton University offer a comprehensive cost and performance evaluation of the role of long-duration energy storage (LDES) technologies in transforming energy systems.
The report advocates for federal requirements for demonstration projects that share information with other U.S. entities. The report says many existing power plants that are being shut down can be converted to useful energy storage facilities by replacing their fossil fuel boilers with thermal storage and new steam generators.
This data-driven assessment of the current status of energy storage technologies is essential to track progress toward the goals described in the ESGC and inform the decision-making of a broad range of stakeholders.
Because storage technologies will have the ability to substitute for or complement essentially all other elements of a power system, including generation, transmission, and demand response, these tools will be critical to electricity system designers, operators, and regulators in the future.

The Ayémé Solar Power Station is a proposed 120 megawatts plant in Gabon. The power station is under development by Solen, an (IPP). The solar farm will be developed in two phases of 60 megawatts each. The energy generated at this power station is expected to be sold to the Energy and Water Company of Gabon (Société d’Energie et d’Eau du Gabon) (SEEG), for distribution in , the capital city of the county and its surro.
