As a new energy power, the new energy industry has developed rapidly in recent years, and the energy storage field has been closely watched. In the face of huge market demand and potential, domestic energy storage enterprises such as sleeping lions are ready to go.

Energy is an important material basis for human survival and social development, and an important cornerstone for the national economy, national security and sustainable development. With the development of human society, mankind's demand for energy resources is increasing day by day, but the ecological environment is deteriorating continuously. In particular, greenhouse gas emissions have led to increasingly severe global climate change. This contradiction has become more serious in recent years. At present, China has become the world's largest energy producer and consumer. China's demand for energy has continued to grow. Therefore, it is urgent to adjust the energy structure: on the one hand, we must develop new energy to meet demand, and on the other hand, we must rationally and effectively use renewable energy.

Renewable energy includes wind energy, solar energy, biomass energy, ocean energy, and small hydropower. It is the primary energy that is usually converted into electrical energy. In the development and utilization of renewable energy, power storage technology plays an important role. It is well known that wind and solar energy are discontinuous and unstable during the use process. They need to be stabilized by energy storage systems before entering the network. At the same time, wind power sets using off-grid power generation modes are also essential. On the other hand, there is an imbalance in the use of energy. The energy storage system can be used for the "peak filling" of the power grid, thereby improving the energy utilization rate. In order to promote the large-scale use of renewable energy for power generation, improve the efficiency of alternative energy power stations, and maintain the security of national energy, the study of energy storage technology has important economic and social significance. Industrially developed countries attach great importance to the research and development of large-scale energy storage systems. For example, the Japanese government's "New Sunshine Plan", the U.S. "DOE Project Plan" and the EU's "Framework Plan" all focus on energy storage technology. China also attaches great importance to the development of energy storage technology. High-efficiency energy conversion and energy storage technology have been listed as the priority development technology areas for the future national torch plan. The China energy storage Battery Production and Research Technology Innovation Alliance was established in November 2009. In addition, according to the Outline for the Development of the New and Renewable Energy Industry 2000-2015 issued by the State Economic and Trade Commission, by 2015, the annual production capacity of small wind generating units will reach 50,000 units, and the total output will reach 340,000 units, with a total installed capacity of 105,000 kW and a total output value of about 900 million yuan. Among them, the sales volume of energy storage system should exceed 100 million yuan, and it will certainly promote the development of the energy storage industry.

New energy storage systems based on new concepts, materials, and technologies are emerging, driven by strong social development needs and huge potential markets. Energy storage technology is developing in the direction of large scale, high efficiency, long life, low cost, and no pollution.

Energy storage market-the total capacity is very impressive, user side potential is huge

The Chinese energy storage market is huge. The China Energy Outlook 2030 released by the China Energy Research Association shows that:

The new energy installed capacity will contribute 90 % of the increase in energy consumption, and the power of supporting energy storage devices will be calculated according to 15 % of the wind power and photovoltaic installed capacity. By 2030, the demand for energy storage batteries is expected to reach 850 million kWh, which will be calculated at a price of 1,200 yuan per kilowatt-hour energy storage system(lithium battery). China's scenic energy storage market is expected to reach 1 trillion yuan(RMB).

At the China Manufacturing Summit in early January, Dongmingzhu, Dalian Wanda Group, Zhongji Group, and Zhuhai Yinlong New Energy Co., Ltd. signed a capital increase agreement and jointly increased their capital by 3 billion yuan. It obtained 22.338 % of Zhuhai Yinlong's equity.

In the current application field, the three major areas of energy storage include large-scale scenery storage, backup power supply for communication base stations, and household storage energy. Among them, the reserve power field of the communication base station currently accounts for a large proportion. The family storage energy has a larger space for further development and expansion through the wave of "energy households" set off by Tesla. The large-scale scenery storage energy seems to have a little momentum in the short term.

However, in the case of lithium electrons, not all lithium batteries are suitable for each energy storage field. The figure below shows the share of China's energy storage capacity in various fields from 2000 to 2016.

These markets, which were previously rarely used due to the economic reasons for energy storage systems, will erupt rapidly in the near future:

According to reports, by 2030, the annual production capacity of electric vehicles will reach 20 million vehicles, the use of power cells will greatly reduce the cost of the energy storage industry, and the rapid development of new energy vehicles will also promote the large-scale expansion of the energy storage industry.

A number of policies have promoted industrial development at the same time -- energy storage has been named in a number of policies, including the Action Plan for Innovation in the Energy Technology Revolution(2016-2030), the Outline of the National Innovation-Driven Development Strategy, and the Implementation Plan for China's Manufacturing 2025-Energy Equipment. These policies describe the road map for the innovative development of energy storage technologies and focus on key technologies, testing and demonstration, and technology equipment for energy storage.

The steady development of the distributed photovoltaic industry -- distributed photovoltaic is undoubtedly a stable and powerful needle for the development of the energy storage industry. Clean energy and energy storage build energy ecosystems for each other to build a solid platform for each other. According to the statistics of the National Energy Bureau, by the end of June 17, The National distributed photovoltaic installed capacity reached 17.43 million kilowatts.
