On March 21, 2022, the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) jointly released the Implementation Plan for the Development of New Energy Storage Technologies during the 14th Five-Year Plan Period (the 14 th FYP for Energy Storage), which calls for a wider ecosystem of government and private entities to build the energy storage sector and emphasizes the role of market forces, including generation utilities and independent service providers, in investing in storage projects.

Total investment in building energy storage projects has exceeded 100 billion yuan since 2021, making the sector a “new driving force” for China’s economic development, said Bian Guangqi, an NEA official.

China’s energy storage sector nearly quadrupled its capacity from new technologies such as lithium-ion batteries over the past year, after attracting more than 100 billion yuan (US$13.9 billion) in direct investment over the past couple of years.
[WANG ZHENG/FOR CHINA DAILY] China's power storage capacity is on the cusp of growth, fueled by rapid advances in the renewable energy industry, innovative technologies and ambitious government policies aimed at driving sustainable development, experts said.
Throughout 2020, energy storage industry development in China displayed five major characteristics: 1. New Integration Trends Appeared The integration of renewable energy with energy storage became a general trend in 2020.
Of this global capacity, China’s operational energy storage project capacity totaled 32.7GW, a growth of 4.1% compared to Q2 of 2019. Global operational electrochemical energy storage project capacity totaled 10,112.3MW, surpassing a major milestone of 10GW, an increase of 36.1% compared to Q2 of 2019.

Pumped hydropower is the most common type of energy storage in use globally, often supporting electricity grids that rely on solar or wind power. It works by pumping water to a storage reservoir at the top of a hill when energy demand is low, and releasing it downhill under pressure to power turbines and move. . As demand for wind and solar power increases, so systems for accurately forecasting their availability are becoming more important to power companies in China, says Fei Wang, a. . Storing green energy — and predicting when it might arrive — are both key research areas to help China reach its carbon-neutral goals. But further innovation is needed into how energy is generated. In October. . In August 2021, researchers at the Institute of Engineering Thermophysics, part of the Chinese Academy of Sciences (CAS) in Beijing, turned. [pdf]

In the first half of 2023, China's new energy storage continued to develop at a high speed, with 850 projects (including planning, under construction and commissioned projects), more than twice that of the same period last year. The newly commissioned scale is 8.0GW/16.7GWh, higher than the new scale level last year (7.3GW/15.9GWh).
The large-scale development of energy storage technologies will address China’s flexibility challenge in the power grid, enabling the high penetration of renewable sources. This article intends to fill the existing research gap in energy storage technologies through the lens of policy and finance.
According to incomplete statistics from CNESA DataLink Global Energy Storage Database, by the end of June 2023, the cumulative installed capacity of electrical energy storage projects commissioned in China was 70.2GW, with a year-on-year increase of 44%.
While energy storage development is accelerating in China and other higher-income countries, the share of investment volume in storage technologies out of all forms of clean energy investments is very small.
Of these, 39.8 GW is used in pumped-storage hydropower (PSH), which is the most widely used storage technology. The share of novel energy storage technologies represents only 12.5% of the total installed capacity in China, where electrochemical storage is the most technically viable technology, followed by fast-growing compressed-air storage.

This article will focus on the top 10 industrial and commercial energy storage manufacturers in China including BYD, JD Energy, Great Power, SERMATEC, NR Electric, HOENERGY, Robestec, AlphaESS, TMR ENERGY, Potis Edge, explore how they stand out in the fierce market competition, and how they lead the development direction of China and the global energy storage industry.
