Electric energy storage installed capacity

What types of energy storage are included?

Other storage includes compressed air energy storage, flywheel and thermal storage. Hydrogen electrolysers are not included. Global installed energy storage capacity by scenario, 2023 and 2030 - Chart and data by the International Energy Agency.

What is the RTE of electrical energy storage?

The round-trip efficiency (RTE) of electrical energy storage systems, such as batteries and supercapacitors, can be higher than 80%. However, the end use and generation locations need to be in close proximity. Liquid hydrogen and methanol, despite also being alternative energy vectors, have lower RTE values as estimated in previous studies.

How many gigawatts of energy are installed in 2023?

The country's installed new-type energy storage capacity had reached 31.39 gigawatts by the end of 2023, of which 22.6 gigawatts were newly installed in that year alone, which was nearly 10 times that at the end of 2020, according to the National Energy Administration (NEA).

What are the benefits of energy storage power plants?

The energy storage power plants help improve the utilization rate of wind power, solar and other renewable sources, thus promoting the proportion of new energy consumption. In the first half of 2023, China's installed renewable energy capacity surpassed coal power for the first time in history.

Why do we need energy storage facilities?

The energy storage facilities serve to iron out electric use volatility in peaks and troughs and, more importantly, facilitate the utilization of the country's growing clean energy amid its efforts to pursue low-carbon development.

Will Guizhou become a new energy storage center in 2025?

By 2025, Guizhou aims to develop itself into an important research and development and production center for new energy power batteries and materials. Recently, China saw a diversifying new energy storage know-how. Lithium-ion batteries accounted for 97.4 percent of China's new-type energy storage capacity at the end of 2023.
