Dai Jianfeng, a deputy chief engineer of China Electric Power Planning and Engineering Institute, said the new energy storage in China has been developed through diverse technology routes. According to him, lithium-ion battery is still dominant at present, but the development of compressed air and liquid flow battery is accelerating.
In China, RES are experiencing rapid development. However, because of the randomness of RES and the volatility of power output, energy storage technology is needed to chip peak off and fill valley up, promoting RES utilization and economic performance.
Li added that China's dominance in energy storage technology, particularly in battery cell production, places it in a leading position to shape global storage standards. At the end of the first half, power storage capacity in China surpassed 100 GW, reaching 103.3 GW, a 47 percent year-on-year increase.
And accompanying with the construction of smart grid, the grid connection of RES, and the popularization of EV, China's demand for energy storage is vigorous. However, China still has a long distance to realize the commercialization of energy storage and this phenomenon is general worldwide because of the immature technology.
At the end of the first half, power storage capacity in China surpassed 100 GW, reaching 103.3 GW, a 47 percent year-on-year increase. New energy storage systems now account for nearly 50 percent of the total, with lithium battery storage maintaining a dominant position in this sector, said Li.
China has created an energy storage ecosystem with players throughout the supply chain. The upstream players are mainly battery and raw materials manufacturers, with many benefitting from first-mover advantage. Chinese manufacturers have gained a substantial market in this domain.
