Through comprehensive examination on the cost and industrial foundation of various energy storage methods in China, this paper clarified the advantages of lithium-ion batteries and hydrogen at duration less than 10h and higher than 48h respectively, especially after 2035.
Statistics show the cost of lithium-ion battery energy storage systems (li-ion BESS) reduced by around 80% over the recent decade. As of early 2024, the levelized cost of storage (LCOS) of li-ion BESS declined to RMB 0.3-0.4/kWh, even close to RMB 0.2/kWh for some li-ion BESS projects.
Energy storage refers to storing surplus energy if the generation process of renewable energy is random and fluctuates. When renewable power cannot meet the demands, the stored energy is released to compensate for the inadequate power. 3. Which kind of energy storage is suitable for China?
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.
Recently, there has been an increase in the installed capacity of photovoltaic and wind energy generation systems. In China, the total power generated by wind and photovoltaics in the first quarter of 2022 reached 267.5 billion kWh, accounting for 13.4% of the total electrical energy generated by the grid .
The decline in costs for solar power and storage systems offers opportunity for solar-plus-storage systems to serve as a cost-competitive source for the future energy system in China. The transportation, building, and industry sectors account, respectively, for 15.3, 18.3, and 66.3% of final energy consumption in China (5).
