High cost of energy storage

As we all know, solar energy and wind energy have characteristics such as discontinuous, unstable and uncontrollable. The popularization and application of renewable energy power generation must be supported by large-scale energy storage technologies in order to ensure safe and stable power supply, and at the same time solve the problem of abandoned light and wind Bottleneck problem. However, China's energy storage technology is on the eve of large-scale development. The high cost of energy storage has deterred many businesses. At present, energy storage technology is not simply a matter of research and development. The more pressing issue is the question of who will pay for high costs.

Taking the Zhangbei Scenic Reserve project as an example, according to the relevant person in charge, the energy storage system configured can increase the utilization rate of wind power by 10% to 20%, and increase the annual electricity revenue by about 10 million to 20 million yuan, but only energy storage. The annual depreciation of the battery is more than 30 million yuan. Compared with the configuration of energy storage systems, direct wind disposal is more economical. In fact, many people in the industry refer to the development of energy storage as “paying for the inside”. Currently, energy storage devices are all in the demonstration stage, and few gains can be made.

The reason why this phenomenon occurs is that China's energy storage is in the early stage of development, and the problems of miscellaneous technical lines, lack of standards, and high costs have seriously hindered the normal development of the industry. At the event of the Zhongguancun Industry Alliance Energy Storage Salon, industry insiders also appealed that at present, China still lacks a commercial mechanism “who will pay for energy storage”. In particular, it has not introduced energy storage similar to Japan and the United States. As a supportive policy for independent industries.

In response to the above issues, relevant departments in China are also stepping up policy research and development of routes for energy storage industries. The National Energy Administration is studying the energy storage technology and policy roadmap. It will form specific plans under the guidance of the government as well as practical and practical policies, and will increase support for the energy storage industry. Some analysts believe that the implementation of the quota system and the development of distributed photovoltaics will force the introduction of energy storage policies.
