The research and development of energy storage technology has been paid much attention by many countries. In a sense, the application degree of energy storage technology determines the development level of new energy, which shows the importance of energy storage industry. Driven by factors such as the decline of PHOTOVOLTAIC FIT, household light storage subsidy, tax investment credit, and intelligent networked control of energy, the world's major energy storage market is booming with a promising future.
The necessity of global energy storage industry development
Since industrialization, fossil energy, which supports the development of human society, has been exhausted. Environmental problems caused by long-term massive consumption of fossil energy, as well as related global climate change, have affected human survival on earth, and are common challenges faced by mankind.
In order to solve the contradiction between increasing energy demand and insufficient fossil energy supply, and to cope with the severe challenges of environmental pollution and warming, the global energy field is undergoing profound changes.
First of all, in the development of primary energy supply, increase the development and utilization of new energy, gradually replace fossil energy, promote the transformation of energy development mode. New energy has played an important role in meeting energy demand, improving energy structure and reducing environmental pollution, and the proportion of new energy in energy has been increasing year by year.
Secondly, promote the reform of energy transmission and distribution, and increase the construction of smart grid. Smart grid, namely "grid 2.0", is based on the traditional electric power system, through the integration of new energy, new materials, new equipment and advanced sensor technology, information technology, control technology, energy storage technology and other new technology, the formation of a new generation of electric power system, has such characters as highly informationization, automation, interaction, can better realize safe, reliable, economic and efficient operation of the grid.
Finally, change in energy use. The change in energy use is mainly manifested in two aspects: first, vigorously carrying out energy conservation and emission reduction; second, the rise of new energy products.
However, as a result of new energy generation has instability and

The total installed capacity of electrochemical energy storage projects in the world is growing rapidly on the whole, but the growth rate has declined in recent years. By the end of 2015, there were 318 electrochemical energy storage projects in the world, and the cumulative installed capacity (2000-2015) was 890.9MW, an increase of 12% over the previous year, and the growth rate decreased by 7 percentage points.

By region, the United States, Japan and China are among the top three countries in terms of electrochemical energy storage accumulative installations, accounting for 44%, 35% and 12% respectively. Chile is the only South American country in the top 10 of installed storage capacity in the world, while Germany has the largest proportion of installed storage capacity in Europe.

The development prospect of global energy storage industry
According to the data, in 2015, the installed capacity of new energy storage + renewable energy was about 196.2MW. With the continuous decrease of energy storage technology cost and the implementation of compensation mechanism, it is estimated that by 2025, the installed capacity of new energy storage + renewable energy will exceed 12.7GW. It can be seen from the forecast data that all sectors of the world have confidence in the rapid development of the future energy storage market.
