Thanks to CTOnews.com netizens, assassins for their clues delivery! CTOnews.com, November 6, according to Dalian Institute of Chemical Industry, Chinese Academy of Sciences, on October 30, the world's largest 100 MW liquid flow battery energy storage and peak shaving power station was officially connected to the grid on October 30, with the technical support of Li Xianfeng from the Energy Storage Technology Research Department (DNL17) of Dalian Chemical Institute.

The power station is built and operated by Dalian Hengliu Energy Storage Power Station Co., Ltd., and the battery system is designed and manufactured by Dalian Rongke Energy Storage Technology Development Co., Ltd. The project is the first national large-scale chemical energy storage demonstration project approved by the National Energy Administration, with a total construction scale of 200MW (MW) / 800MW (MWh). This time, the first phase of the power station will be connected to the grid, with a scale of 100MW (MW) / 400MW (MWh).

According to reports, renewable energy generation has intermittence and volatility, after its large-scale access to the power grid, the power system must have a certain strain and response capacity in order to ensure the reliability of renewable energy power supply. Energy storage technology can effectively solve the problems of power system operation security, power balance and renewable energy consumption, and is a necessary technical support for the full development and utilization of renewable energy.

The energy storage technology of all-vanadium flow battery uses different valence vanadium ions as active materials to realize the conversion between electric energy and chemical energy based on the oxidation or reduction reaction of vanadium ions in positive and negative electrode electrolytes. thus the large-scale storage and release of electric energy can be realized. It has high safety, good reliability, large scale of output power and energy storage capacity, long life, high performance-to-price ratio, recyclable electrolyte and environment-friendly, so it has a good application prospect in the field of large-scale energy storage.

CTOnews.com learned that according to official introduction, the Dalian liquid flow battery energy storage and peak shaving power station connected to the grid uses the all-vanadium flow battery energy storage technology independently developed by Dalian Institute of Chemical Engineering of the Chinese Academy of Sciences, which is equivalent to Dalian's "electric bank" to realize peak cutting and valley filling in the power grid system. The main function is to provide auxiliary services such as peak regulation and frequency modulation for the power grid. To a certain extent, it can alleviate the stability problems caused by large-scale renewable energy grid, and promote the absorption of power system for renewable energy generation, and improve the economy of power system operation. Dalian liquid flow battery energy storage peak-shaving power station will improve the grid connection rate of renewable energy, balance power grid stability and improve power grid reliability, which is of great significance to accelerate the application of large-scale energy storage in power peak regulation and renewable energy grid connection in China.

The Energy Storage Technology Research Department has always adhered to the innovative development mechanism of "production, learning, research and use", constantly solving the key scientific and technical problems existing in the industrialization of all-vanadium flow battery, and breaking through the key core technology of energy storage of all-vanadium flow battery. a series of leading international technological achievements have been achieved, industrialization promotion has been carried out at home and abroad, and the export of China's liquid flow battery energy storage technology to developed countries has been realized. It reflects the international leading position of Dalian Institute of Chemical Engineering of Chinese Academy of Sciences in this field.

According to the Securities Times, there are 23 companies with liquid flow battery business in the A-share market, and more than half of the companies' net profit increased in the first three quarters of this year compared with the same period last year. In terms of valuation, as of November 4, more than 60% of concept stocks had a rolling price-to-earnings ratio of less than 30 times.
