This report provides a brief overview of the role of energy storage against the background of current trends in power systems with an emphasis on developing countries.
Which countries have a literature search for energy storage technologies?
In this section, relevant literature on energy storage technologies was searched for China, the United States, Japan, and European economies. The specific numbers of collected literature are shown in Table A1. Table A1. Number of literature searches in the field of EST.
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.
Which countries publish the most energy storage publications?
Thermal energy storage and chemical energy storage have similar overall publication volumes, with China and Europe leading the way. The United States demonstrates an initial increase in publication numbers, followed by stable fluctuations, while Japan maintains a relatively consistent level of publications within a certain range. 4.2.
Which countries have the most energy storage capacity?
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.

Are energy storage technologies passed down in a single lineage?
Most technologies are not passed down in a single lineage. The development of energy storage technology (EST) has become an important guarantee for solving the volatility of renewable energy (RE) generation and promoting the transformation of the power system.
Energy storage is not a new technology. The earliest gravity-based pumped storage system was developed in Switzerland in 1907 and has since been widely applied globally. However, from an industry perspective, energy storage is still in its early stages of development.
