Recently, at the "Vast Weather Patterns in Sichuan" series of thematic press conferences held by the Sichuan Provincial Government Information Office, specifically the Panzhihua session, it was introduced that Panzhihua has developed new productive forces according to local conditions, with the vanadium battery energy storage industry being included in the list of new industrial tracks in the province. Efforts are being made to build a national key laboratory for the comprehensive utilization of vanadium and titanium resources, focusing on the construction of a hydrogen energy industry demonstration city and "China's Vanadium Battery Capital." The first vanadium battery energy storage industry development plan in the country has been implemented. Panzhihua City, known for its abundant vanadium and titanium resources, has fully leveraged its unique resource advantages and strong industrial foundation to actively layout and rapidly develop in the vanadium battery energy storage industry in recent years:

1. Development Plan Release: Panzhihua City has released the "China's Vanadium Battery Capital" - Panzhihua City Vanadium Battery Energy Storage Industry Development Plan (2023-2030), aiming to seize new opportunities in energy storage industry development, fully leverage Panzhihua's resource and industrial foundation advantages, and fully build "China's Vanadium Battery Capital";

2. Policy Support: The Sichuan Provincial Department of Economy and Information Technology and other departments have jointly issued the "Implementation Plan for Promoting High-Quality Development of Vanadium Battery Energy Storage Industry," clearly supporting Panzhihua City to build a full industry chain cluster of vanadium battery energy storage;

3. Introduction of Leading Enterprises: Panzhihua City has successfully signed contracts to introduce leading enterprises such as Dalian Rongke and State Power Investment Corporation, forming an annual production of thousands of tons of high-purity vanadium pentoxide and a total of 120,000 cubic meters of vanadium electrolyte production and complete machine manufacturing production line projects;

4. Industry Chain Construction: It has more than 100 various innovation and entrepreneurship platforms, including the National Key Laboratory for Comprehensive Utilization of Vanadium and Titanium Resources and the National Standardization Technical Committee for Comprehensive Utilization of Vanadium and Titanium Magnetite, and has established the first vanadium and titanium metal storage company in the country. At the same time, it has joined hands with well-known companies in the industry to explore and build a "vanadium resource development - key materials - stack manufacturing - system integration - terminal application" full industry chain in Panzhihua, promoting the high-quality development of Panzhihua's vanadium industry;

5. Demonstration Project Construction: Panzhihua City is accelerating the construction of the State Power Investment Corporation's 100MW/500MWh vanadium battery energy storage power station demonstration project. The EPC bidding has been completed, and the plan is to start construction in July, with the first phase expected to be connected to the grid by the end of the year.

It should be noted that Panzhihua is not the only region in China to seize the vanadium battery energy storage industry. Another vanadium resource-rich area, Chengde in Hebei, mentioned in the "National Carbon Peak Pilot Implementation Plan" will use its own advantages to build "China's Vanadium Valley." According to policies issued by local governments and development and reform departments in various provinces and cities in the past two years, it can be seen that the number of provinces and cities encouraging and even prioritizing energy storage technology routes with inherent safety characteristics, such as all-vanadium liquid flow energy storage, is gradually increasing. In addition to the incompletely organized provincial and regional vanadium battery industry policies, other provinces such as Zhejiang and Inner Mongolia have also mentioned the exploration of liquid flow battery energy storage technology and policy support in their carbon peak pilot implementation plans. Resource endowment is also affecting the choices and routes of different provinces and cities, and most provincial and city policies tend to be consistent, emphasizing basic requirements such as inherent safety, energy storage ratio, and duration; at the same time, with the change of market demand, local policies are gradually shifting from "encouragement" to "requirements," promoting the commercialization process of liquid flow energy storage technology. With the acceleration of global energy transformation, energy storage technology, as a key support for the development of new energy, its safety issues are becoming increasingly prominent. In 2024, several energy storage safety accidents occurred worldwide, causing casualties and property losses, and once again sounding the alarm for energy storage safety. The development of new energy storage technologies with inherent safety, large capacity, low cost, and long life is particularly important and urgent. Firstly, in terms of safety requirements, all-vanadium liquid flow batteries are actively promoted because of their inherent safety, with no risk of combustion or explosion; secondly, in terms of energy storage ratio, most provinces and cities require new wind and photovoltaic projects to be equipped with 10%-20% energy storage facilities. Regarding energy storage duration, policies generally require more than 2 hours, and some regions even require 4 hours. Vanadium batteries, especially all-vanadium liquid flow batteries, have a very long cycle life, perfectly meeting the long-term energy storage needs. Under 100% charge and discharge cycles, vanadium batteries can charge and discharge more than 20,000 times, with a service life of more than 10 years. This means that vanadium batteries can maintain long-term stable operation in long-term energy storage applications, reducing the frequency of battery replacement and maintenance costs.

With the increase of wind and photovoltaic power penetration, the demand for energy storage in the power system is growing. The long-term advantage of liquid flow batteries can effectively alleviate the phenomena of "abandoning wind" and "abandoning light." At the same time, their high safety and environmental protection characteristics are in line with the national "dual carbon" goals, adapting to the needs of large-scale long-term energy storage. Both national and local governments have introduced a series of supporting policies to promote the development of new energy storage technologies. Under the superposition of multiple factors, liquid flow battery technology industries, represented by vanadium batteries, have become the best entry point for current long-term energy storage layout with their inherent safety and long life advantages. In recent years, liquid flow battery technology has made significant progress. In addition to vanadium batteries, zinc-iron, zinc-bromine, iron-chromium, and sulfur-iron liquid flow battery technology routes are gradually maturing, each with its advantages, showing a diversified development pattern, providing more options for long-term energy storage layout.
