How I Think About The Global ESS Market?

- Jun 19, 2019-

    Energy storage is an important part and key supporting technology of smart grid, renewable energy high proportion energy system, energy Internet. With the introduction of government support policies for energy storage industry, the scale of investment in energy storage market is increasing, the layout of industrial chain is constantly improved, the business model is becoming more and more diverse, and the application scenario is accelerated. In China, the introduction of a series of policies for the great development of the energy storage industry, the industry to the outbreak of the critical point, the spring of energy storage is coming. This report combs and studies the basic situation of the global energy storage market, the relevant policies of the energy storage industry, the application of energy storage and the business model, and on this basis, analyzes the development trend of the energy storage market.


    In 2017, the United States, China and Japan still occupy the leading position in the installation of energy storage projects, among which the United States is still the largest energy storage market in the world. According to the global energy storage report released by gtm research, the world's new energy storage capacity is 2.3 gigawatts per hour in 2017, of which the United States ranks first in the world with 431 megawatts of new energy storage hours. By the end of 2017, cumulative U.S. energy storage deployment reached 1.08 gigawatts, and deployment is expected to exceed 1.2 gigawatts in 2018. According to the Yano Institute of Economic Research, Japan's energy storage market will also maintain rapid growth, with the market expected to reach 3.307 gigawatts per hour by 2020. Although the energy storage industry in China started late, the development rate of energy storage industry in recent years is remarkable.

    At present, domestic energy storage focuses on demonstration application, actively explores the commercial application of energy storage under different scenarios, technology, scale and technical route, and standardizes the relevant standards and testing system at the same time. According to the incomplete statistics of (cnesa) global energy storage project database of Zhongguancun Energy Storage Industry Technology Alliance, the scale of energy storage planned and under construction in China during 2017 is nearly 1.6 gigawatts, accounting for 34% of the global planning and construction scale, and the scale of energy storage and transportation in China is accelerating. By the end of 2017, China had put into operation energy storage projects with a cumulative installed scale of 28.9 gigawatts, an increase of 19 percent over the same period last year. 

   Similar to the global energy storage market, the cumulative installed scale of pumped storage capacity in China accounts for the largest proportion, close to 99%, but slightly decreased compared with the same period last year. The cumulative installed scale of electrochemical energy storage ranked second, with 389.8 megawatts, up 45 percent from the same period last year, accounting for 1.3 percent, an increase of 0.2 percentage points over the previous year. Among all kinds of electrochemical energy storage technologies, lithium ion batteries account for the largest cumulative installation ratio, with a specific gravity of 58%.
