Analysis of the current stage of energy storage field

Are there any gaps in energy storage technologies?

Even though several reviews of energy storage technologies have been published, there are still some gaps that need to be filled, including: a) the development of energy storage in China; b) role of energy storage in different application scenarios of the power system; c) analysis and discussion on the business model of energy storage in China.

What is the nurturing stage of the energy storage industry?

2) The Nurturing Stage, from 2014 to 2016, is the nurturing stage of the energy storage industry. In order to promote the development of the energy storage industry, during this period, the number of energy storage policies in China increased.

What is the foundation stage of energy storage policy?

1) The Foundation Stage, from 2010 to 2013, is the initial exploration period of the energy storage policy, laying a solid foundation for the development of the energy storage industry. In this stage, the R&D of technology became the primary problem for government.

What are the relevant policies for energy storage?

The relevant policies during this period were mainly about R&D on the power grids that incorporate energy storage technologies, and demonstration application of energy storage technologies in the field of renewable energy. These have laid a solid foundation for the development of energy storage.

What role does energy storage play in the future?

As carbon neutrality and cleaner energy transitions advance globally, more of the future's electricity will come from renewable energy sources. The higher the proportion of renewable energy sources, the more prominent the role of energy storage. A 100% PV power supply system is analysed as an example.

How has energy storage changed over 20 years?

As can be seen from Fig. 1, energy storage has achieved a transformation from scientific research to large-scale application within 20 years. Energy storage has entered the golden period of rapid development. The development of energy storage in China is regional. North China has abundant wind power resources.
