In the Sichuan Energy Investment Building located in the middle section of Jiannan Avenue in Chengdu, the all-vanadium redox flow battery energy storage demonstration project invested and built by Sichuan Chemical Industry Group covers an area of 560 square meters. The all-vanadium redox flow battery has the advantages of high safety, strong capacity expansion, long cycle life, and low life-cycle cost. It is currently a relatively mature commercialized flow battery and has great potential in the field of long-term energy storage.
“What we are seeing now is a set of 50kW/300kWh photovoltaic power generation integrated energy storage system and a set of 50kW/300kWh peak-shaving (peak-shaving and valley-filling) energy storage system completed in September 2022. Equipment debugging and optimization, focusing on improving energy efficiency and realizing long-term stable operation of the system.” The relevant person in charge of Sichuan Chemical Industry Group introduced to the research team.
It is reported that on the basis of the stable operation of the above-mentioned demonstration projects, Sichuan Energy Investment Yongfu Company’s annual production of 2000 cubic meters of all-vanadium liquid flow electrolyte pilot project has landed in Ya’an, and the operation is in good condition. After the completion of the pilot test, it plans to fully industrialize; The 1MWh all-vanadium redox flow battery energy storage system unit module technology development and energy storage system performance upgrade project is also under construction.
The all-vanadium redox flow battery energy storage project is just a microcosm of the transformation and development of Sichuan Chemical Group. The research team saw from the “14th Five-Year Plan” of Sichuan Chemical Industry Group that the company combined market demand and Sichuan’s local mineral resource endowment, focusing on the development of electrochemical energy storage such as electrolyte and other battery materials, new energy batteries, and energy storage system applications; Combining the existing PTA and other new material industry resources of Sichuan Energy Investment Group, developing the biological method PDO project and the downstream PTT polyester industry chain, and laying out green chemical new material industries such as bio-based materials; Combining Sichuan Energy Investment Group’s hydrogen energy in Panxi area Industrial layout, promoting the green and low-carbon transformation and upgrading of the traditional chemical industry, focusing on the development of new green energy chemical industries based on electrolysis of water for hydrogen production and downstream chemical industry chains, and realizing the coupled development of green hydrogen energy and chemical industry in the Panxi area.
It is not difficult to see that the industrial development direction, layout and key projects of Sichuan Chemical Industry Group, it not only closely meet the market demand of local regional economic development, but also highlight the green and low-carbon characteristics.
