"Kechuangban Daily" (Editor Zheng Yuanfang), According to CCTV news reports, the world's largest 100MW/400MWh all-vanadium redox flow battery energy storage power station has completed the main engineering construction and entered the single module debugging stage.
The power station is the first phase of the "200MW/800MWh Dalian Flow Battery Energy Storage Peaking Power Station National Demonstration Project". is the first 100MW large-scale electrochemical energy storage national demonstration project approved by the National Energy Administration. adopts all-vanadium redox flow battery energy storage technology independently developed by Dalian Institute of Chemical Physics.
It is expected that the project will complete grid-connected commissioning in June this year. After the power station is completed, the output power will reach 100MW and the energy storage capacity will reach 400MWh, which is equivalent to storing 400,000 kWh of electricity.
In addition, this project will also alleviate the pressure on local power grids for peak shaving, promote the application of large-scale energy storage in my country's power peak shaving and renewable energy grid integration, and provide support for the energy revolution and energy structure adjustment to achieve the "double carbon" goal. Technical Support.
All-vanadium redox flow batteries are expected to become the best choice for large-scale energy storage
Today, many stocks in the energy storage sector rose. This main line of downturn in the past three months has once again attracted market attention.
All-vanadium redox flow battery is a form of electrochemical energy storage. At present, the mainstream of electrochemical energy storage in my country is lithium batteries, but other energy storage technologies such as all-vanadium liquid sulfur have gradually entered the market.
For example, the "Announcement on the First Batch of "New Energy + Energy Storage" Pilot Demonstration Projects" previously released by Shanxi Province covers 15 projects and a variety of energy storage technologies. In addition to lithium iron phosphate , All-vanadium flow battery projects have the largest number.
Under normal circumstances, the main requirements for large-scale energy storage are safety and life cycle. However, in the "Interim Measures for the Safety Management of Electrochemical Energy Storage Power Stations (Draft for Comments)" issued by our country in the second half of last year, it was once again emphasized that electricity The core requirement of chemical energy storage is safety - this is the "weak spot" of lithium batteries. In comparison with
, vanadium battery has more outstanding safety performance, no combustion risk, and also has advantages in terms of cost performance and environmental protection throughout its life cycle. In addition, my country is a major vanadium resource country, with reserves ranking first in the world, and it occupies a favorable position in terms of supply security and pricing power.
On the other hand, the cost of vanadium batteries is also falling rapidly, and the cost bottleneck that makes it difficult to commercialize on a large scale is being eliminated.
After comprehensive consideration, Guotai Junan pointed out that as the "king of energy storage", my country's all-vanadium redox flow battery is on the eve of large-scale industrialization. In the future, vanadium batteries will completely lead lithium batteries and dominate the (large-scale) energy storage field. It is expected that the penetration rate of vanadium batteries in the energy storage field will reach 15%-20% in 2025. All-vanadium flow batteries may be the best choice for large-scale energy storage.
However, the consumption of vanadium pentoxide for a 1GW vanadium battery is about 10,000 tons. Analysts estimate that assuming the penetration rate of vanadium batteries in the energy storage field reaches 15%, the new demand for vanadium pentoxide will be equivalent to nine times the size of the vanadium battery market in 2020, and a supply gap for vanadium resources is looming.
At present, State Power Investment Corporation, National Energy Group and some local energy groups, China Resources, Shanghai Electric , etc. are actively deploying vanadium batteries. In addition, Panzhihua Iron and Steel Vanadium Titanium is the largest vanadium product manufacturer in my country; Anning Co., Ltd. is the leader in the domestic titanium concentrate industry; and Hegang Co., Ltd. is the world leader in vanadium product production technology.
