Redox Flow Battery for Energy Storage

Saving fossil energy and the widespread application of renewable energy have become important strategies of world government to maintain sustainable development of the society. With the rapid development of renewable energy (such as solar and wind energy) and the pushing forward of smart grid, large-scale and high-efficiency energy storage technology is urgently needed to remove the random and intermittent natures of the renewable energy and increase the compatibility of the renewable energy to the grid. The vanadium redox flow battery (VRB) becomes one of the most promising technologies with advantages of long cycle life, high energy convention efficiency, flexible system design, deep-discharge capability and low cost. In this paper, current progress on the VRB technology and the work undertaken by DICP will be described in detail.
