Keywords:Electrochemical energy storage · Life-cycle cost · Lifetime decay · Discharge depth 1 Introduction Electrochemical energy storage is widely used in power systems due to its advantages of high specific energy, good cycle performance and environmental protection .
The operation and maintenance costs of electrochemical energy storage systems are the labor,operationandinspection,andmaintenance coststoensurethattheenergystorage system can be put into normal operation, as well as the replacement costs of battery fluids and wear and tear device , which can be expressed as:
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).
The learning rate of China's electrochemical energy storage is 13 % (±2 %). The cost of China's electrochemical energy storage will be reduced rapidly. Annual installed capacity will reach a stable level of around 210GWh in 2035. The LCOS will be reached the most economical price point in 2027 optimistically.
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.
