With the continuous expansion of global renewable energy installation and deep adjustment of energy structure, energy storage technology has become a key link connecting new energy supply and power demand. In the first half of 2026, global energy storage installations exceeded 200GW for the first time, marking the formal entry of the energy storage industry into a new stage of large-scale development. This article will deeply explore the key role of energy storage technology in the energy bonus period, analyze industry development trends, and provide professional references for investors.
Energy Storage Industry Reaches Inflection Point, Global Market Reshaped
According to the latest data from the International Energy Agency, global energy storage capacity increased by 68% year-on-year in the first half of 2026, reaching 205GW, an increase of 83GW compared to the end of 2025. This breakthrough growth is mainly due to multiple factors such as increased renewable energy penetration, increased demand for grid stability, and continuous decline in energy storage costs. Among them, the Chinese market contributed 42% of the newly installed global energy storage capacity, becoming the leader in the global energy storage market; Europe and the US market followed, accounting for 28% and 19% respectively.
The explosive growth of the energy storage industry is driven by profound changes in the energy structure. With the acceleration of global carbon neutrality process, the proportion of renewable energy power generation continues to increase. In the first half of 2026, the proportion of global renewable energy power generation has reached 35%, an increase of nearly 15 percentage points compared to 2020. However, the intermittent and volatile characteristics of renewable energy power generation pose huge challenges to grid stability, and energy storage technology has become a key solution to this problem.
In terms of technology routes, lithium battery energy storage still dominates, accounting for 73% of newly installed capacity in the first half of 2026, a significant increase from 58% in 2020. At the same time, long-duration energy storage technologies such as flow batteries, compressed air energy storage, and flywheel energy storage are also developing rapidly, gradually solving the bottleneck problem of limited duration of traditional lithium battery energy storage.

Flow batteries are becoming the mainstream choice in the long-duration energy storage market with their high safety, long life and easy scalability. In the first half of 2026, global flow battery energy storage installations increased by 85% year-on-year, with particularly outstanding performance in the Chinese and US markets. In addition, physical energy storage technologies such as compressed air energy storage and gravity energy storage are also showing great potential in specific application scenarios.
The development of intelligent energy storage management systems is also worthy of attention. Through the integrated application of artificial intelligence, big data analysis and Internet of Things technology, the new generation of energy storage systems can achieve more precise charge-discharge control, more efficient energy management and better economic benefits. According to industry data, the return on investment of projects using intelligent energy storage management systems is 15-20 percentage points higher than traditional systems.
Policy Environment Continues to Optimize, Global Energy Storage Market Enters Accelerated Development Period
Major global economies have successively introduced policy measures to support the development of the energy storage industry, creating a favorable development environment for the industry. In China, the "14th Five-Year Plan" clearly proposes to vigorously develop the energy storage industry and incorporate it as an important part of the construction of a new power system. In the first half of 2026, the National Development and Reform Commission and the National Energy Administration jointly issued the "Guiding Opinions on Further Accelerating the Development of the New Energy Storage Industry", clarifying the development goals and key tasks of the energy storage industry for the next five years.
In the United States, the Inflation Reduction Act provides up to 30% investment tax credits for energy storage projects, greatly stimulating investment enthusiasm in the energy storage market. The EU, through the "European Green Deal" and "REPowerEU" plans, regards energy storage as a key technology to achieve energy independence and carbon neutrality goals, setting ambitious development targets.
Innovation in market mechanisms also provides important support for the development of the energy storage industry. Globally, electricity market ancillary service mechanisms continue to improve, and the ability and revenue of energy storage to participate in peak shaving, frequency regulation, and reserve services are gradually increasing. In addition, the development of new market mechanisms such as capacity markets and green certificate trading has created diversified profit models for energy storage.
