Energy storage 2020

What is the energy storage Grand Challenge?

This report, supported by the U.S. Department of Energy’s Energy Storage Grand Challenge, summarizes current status and market projections for the global deployment of selected energy storage technologies in the transportation and stationary markets.

Will energy storage grow in 2022?

The global energy storage deployment is expected to grow steadily in the coming decade. In 2022, the annual growth rate of pumped storage hydropower capacity grazed 10 percent, while the cumulative capacity of battery power storage is forecast to surpass 500 gigawatts by 2045.

Where will stationary energy storage be available in 2030?

The largest markets for stationary energy storage in 2030 are projected to be in North America (41.1 GWh), China (32.6 GWh), and Europe (31.2 GWh). Excluding China, Japan (2.3 GWh) and South Korea (1.2 GWh) comprise a large part of the rest of the Asian market.

How much energy is stored in the world?

Worldwide electricity storage operating capacity totals 159,000 MW, or about 6,400 MW if pumped hydro storage is excluded. 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.

What is the largest energy storage technology in the world?

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.

Which energy storage technology is most widely used in 2022?

Mechanical technologies, particularly pumped hydropower, have historically been the most widely used large-scale energy storage. In 2022, global pumped storage hydropower capacity surpassed 135 gigawatts, with China, Japan, and the United States combined accounting for almost one third of this value.
