Electrochemical energy storage (EES) technology, as a new and clean energy technology that enhances the capacity of power systems to absorb electricity, has become a key area of focus for various countries. Under the impetus of policies, it is gradually being installed and used on a large scale.
In 2022, 194 electrochemical storage stations were put into operation, with a total stored energy of 7.9GWh. These accounted for 60.2% of the total energy stored by stations in operation, a year-on-year increase of 176% (Figure 4).
In terms of developments in China, 19 members of the National Power Safety Production Committee operated a total of 472 electrochemical storage stations as of the end of 2022, with a total stored energy of 14.1GWh, a year-on-year increase of 127%.
Based on CNESA’s projections, the global installed capacity of electrochemical energy storage will reach 1138.9GWh by 2027, with a CAGR of 61% between 2021 and 2027, which is twice as high as that of the energy storage industry as a whole (Figure 3).
Electrical energy storage systems typically refer to supercapacitors and superconducting magnetic energy storage. Both of these technologies are marked by exceedingly fast response times and high power capacities with relatively low energy capacities.
Chemical energy storage relies on utilizing thermal or electrical energy to drive chemical or physical reactions. These reactions yield stable chemicals that can store energy for long periods of time given the proper storage conditions.
