Recently, the world's largest 5MW/10MWh all vanadium redox flow battery energy storage demonstration project through the acceptance of application system of Liaoning Electric Power Survey and design institute. Vanadium battery is a kind of liquid flow battery. According to the analysis, based on the advantages of vanadium battery, solar energy, wind power and other fields of future market is worth looking forward to space.
Highlight the advantages of cost control
The system is composed of Dalian Branch Energy Storage Technology Development Co Ltd and Dalian Institute of Chemical Physics Chinese Academy of sciences development, since February 22nd this year the grid-connected operation, has been fully put into operation. In the United States in 2012 enacted the energy storage technology development planning, vanadium battery ranked first. The analysis thinks, abandon wind power phenomenon of current our country is becoming more and more serious, the vanadium battery has outstanding advantages in stability, cost control, is expected to become the industry a dark horse.
In fact, Dalian Institute of Chemical Physics took the lead in proposing the redox flow battery standards and to participate in the entire process of Europe flow battery standards, this shows that the international of China's liquid flow battery technology level of recognition, which is important for promoting China's battery industry application.
The monopoly of world vanadium battery technology commercialization is the earliest Japanese Sumitomo, VRB company of canada. After the 2008 financial crisis, Beijing Puneng successful acquisition of Canadian VRB company, and combined with Chinese Academy of Sciences, Central South University and other research units started to domestic development. The current domestic production of vanadium battery business mainly in Beijing, Beijing, Dalian can understand section etc..
The national grid in 2009 April launched the country scenery storage project, the storage battery tender in addition to lithium iron phosphate battery, flow battery in selected vanadium battery supplied by Beijing general. State Grid demonstration project has greatly improved the vanadium battery in new energy storage battery in the field of market position.
The scale is easy to adjust.
Active substance flow batteries exist in liquid form, is not only the active electrode material and electrolyte solution, energy storage volume capacity depends on the liquid storage tank. Design flexibility, ease of module combination, by setting small scale space limit, easy to adjust.
At present, the global more in-depth study of the redox flow battery system has four kinds, including flow for all vanadium redox flow battery battery, zinc-bromine flow battery, Fe-Cr redox flow battery and sodium polysulfide / bromine liquid, and have a commercial demonstration operation experience. Redox flow battery electrochemical polarization, which all vanadium redox flow battery with high energy efficiency, storage capacity, fast charging and discharging, and has the advantages of long service life etc.. Has achieved commercial operation of all vanadium redox flow battery, can effectively smooth wind power generation.
At present, the United States of America, Ireland, Denmark, South Africa, Italy, Canada, Germany and Japan, a plurality of photovoltaic power generation and wind power energy storage projects using vanadium battery. According to the analysis, based on the advantages of vanadium battery, solar and wind power development in the future, the vanadium battery demand for huge space. According to CCID the wisdom of statistical data, in 2010 the global photovoltaic and wind power generation on vanadium battery demand for a total of 53.75GW, forecast to 2020 for 362.5GW.
In addition, in the field of power grid peak shaving, vanadium battery has broad application space. In China's central and western regions as a surplus of electricity, vanadium battery peak shaving means attracted more and more attention. Data shows, 2012 China energy peak areas of vanadium battery demand for 24GW, PV and wind power generation on vanadium battery requirements are 0.625GW and 8GW.
