The core sector of energy storage

What is the new type energy storage industry in China?

The remaining half is comprised primarily of batteries and emerging technologies, such as compressed air, flywheel, as well as thermal energy. These technologies, known as the “ new type ” energy storage in China, have seen rapid growth in recent years. Lithium-ion batteries dominate the “new type” sector.

How many energy storage companies are there in China?

At present, there are nearly 90,000 registered enterprises involved in the energy storage industry, data from the China Industrial Association of Power Sources showed. According to the National Energy Administration, China's energy storage sector, hydropower storage excluded, will enter the stage of large-scale development in 2025.

What is the energy storage system?

The energy storage system includes 1×5 MW×2 h LiB, 1×2 MW×2 h VRFB. And the wind power of 99 MW had been put into operation in August 2012. The system is connected with the 35 kV bus. Through intelligent control, the system stores and releases power according to the coordinating with wind power.

Does China's energy storage industry have a comprehensive study?

However, because of the late start of China's energy storage industry, the comprehensive study for the whole industry is very few. We found a review which provided a relatively comprehensive analysis of the technical and economic issue of it. Compared with other studies, its research has a good comprehensiveness.

What are the core technologies for energy storage?

At this stage, core technologies should be broken through including the screening of high temperature heat storage materials and its device design, the design and manufacture of the core component of CAES, the new material manufacture of chemical energy storage, the energy storage systems integration and energy management.

Why is energy storage industry in China a big problem?

Judging from the present condition, cost problem is the main barrier. And the high performance and high security of the relative technology still need to be improved. Until 2020, energy storage industry in China may not be spread massively and the key point during this period is the technology research .
