Have policy makers in China discussed the likely market share of VRFB in the grid storage market? What kinds of policies have been implemented to support such an endeavor?
Policy makers in China have been actively discussing and supporting the development of vanadium redox flow batteries (VRFB) for grid storage. The Chinese government has implemented several policies and initiatives to boost the adoption of VRFB technology.
One of the key projects is the Dalian Flow Battery Energy Storage Peak-shaving Power Station, which is the world's largest of its kind, with a capacity of 100 MW/400 MWh in its first phase, eventually scaling up to 200 MW/800 MWh. This project is part of a broader national strategy launched in 2016 to develop large-scale flow battery demonstrations across China [oai_citation:1,China connects world’s largest redox flow battery system to grid – pv magazine International](https://www.pv-magazine.com/2022/09/29/china-connects-worlds-largest-redox-flow-battery-system-to-grid/) [oai_citation:2,First Phase of 800MWH World Biggest Flow Battery Commissioned in China - World-Energy](https://www.world-energy.org/article/25949.html).
Additionally, China’s National Energy Administration has banned the use of ternary lithium batteries and sodium-sulphur batteries for energy storage due to safety concerns. This policy shift is aimed at promoting safer alternatives like VRFBs, which use water-based electrolytes and have a lower risk of combustion compared to lithium-ion batteries [oai_citation:3,Vanadium redox flow batteries: a new direction for China’s energy storage? - Fastmarkets](https://www.fastmarkets.com/insights/vanadium-redox-flow-batteries-a-new-direction-for-chinas-energy-storage/).
China is leveraging its large vanadium reserves to support the VRFB industry, with significant investments in VRFB production facilities and projects. For instance, a VRFB factory with a 1,000 MWh annual production capacity is planned for Hubei Province, supporting the development of a 100 MW/500 MWh VRFB system [oai_citation:4,First phase of 800MWh world biggest flow battery commissioned in China - Energy-Storage.News](https://www.energy-storage.news/first-phase-of-800mwh-world-biggest-flow-battery-commissioned-in-china/) [oai_citation:5,First Phase of 800MWH World Biggest Flow Battery Commissioned in China - World-Energy](https://www.world-energy.org/article/25949.html).
The Chinese government has set ambitious goals for renewable energy integration, aiming to install over 1,000 gigawatts of new solar PV and wind power by 2030. This has created a demand for reliable energy storage solutions like VRFBs, which are expected to play a crucial role in achieving these targets [oai_citation:6,China’s largest solar-plus-flow battery project will be accompanied by VRFB ‘gigafactory’ - Energy-Storage.News](https://www.energy-storage.news/chinas-largest-solar-plus-flow-battery-project-will-be-accompanied-by-vrfb-gigafactory/).
Overall, China's policies and strategic investments indicate a strong commitment to expanding the market share of VRFBs in the grid storage sector, positioning the country as a leader in this emerging technology.
