LONDON, Nov. 8, 2016 /PRNewswire/ -- Energy storage finds widespread application in power system, involving power generation, transmission, distribution, and end users. Global cumulative installed capacity of electrical energy storage (EES) (excluding pumped hydro storage, compressed air energy storage and thermal storage) has grown at a CAGR of 18% over the past five years, hitting 946.8MW in 2015. The United States and Japan are leaders by installed capacity of EES, together holding 78% shares.
In 2015, lithium-ion battery and sodium-sulfur battery dominate the world's installed capacity of EES, making up 38% and 36%, respectively; renewable energy grid integration and frequency regulation auxiliary services are two main applications, accounting for 43% and 22%, respectively.
Asia, particularly South Korea and Japan, is the home to the enterprises with larger installed capacity of EES. In 2015, the world's top5 enterprises (by installed capacity of EES) were LG Chem, NEC, NGK, Toshiba, and Samsung SDI.
In 2015, China's installed capacity of EES (excluding pumped hydro storage, compressed air energy storage, and thermal storage) accounted for about 11% of the world's total, at a CAGR of 110% over the past five years. Unlike foreign countries, China attaches great importance to lithium-ion battery technology which shares 66% of China's total installed capacity of EES. Two major applications are distributed generation ?grid (56%) and renewable energy grid integration (35%).
In 2015, most of top10 Chinese enterprises with the largest installed capacity of EES employed lithium-ion battery technology. The first five enterprises were BYD, Dalian Rongke Power, Wanxiang, Zhejiang Narada Power Source, and China Aviation Lithium Battery, seizing a combined 63% share.
BYD: No.1 in China and No. 6 in the world by installed capacity of EES and a representative of lithium-ion battery roadmap. LiFePo4 battery technology for energy storage stations presents clear cost and service life advantages. Customers in energy storage field include State Grid Corporation of China, China Southern Power Grid Co., Ltd, China General Nuclear Power Group, etc.
Dalian Rongke Power: a world-leading supplier of vanadium redox batty (VRB) energy storage system and has the largest installed capacity among Chinese flow battery companies.
Zhejiang Narada Power Source: the largest installed capacity among lead storage battery companies; industry-leading lead-carbon battery storage technology already applied to renewable energy storage, distributed generation ?grid, residential energy storage, etc.
