The global redox flow battery market is set to experience substantial growth, with a projected Compound Annual Growth Rate (CAGR) of 15% during the assessment period from 2023 to 2030. By the end of 2030, the market is expected to reach a value of approximately US$700 million.
Redox flow batteries, a type of electrochemical cell, are gaining prominence as a means of storing and releasing energy. These batteries employ a unique liquid-contained system where two chemical components undergo redox reactions, transferring electrons and generating chemical energy. This energy is separated by a membrane and contained in a stack comprising anodes and cathodes, each with its own tank. Additional components include bipolar plates and membranes, and the stack's size and number are determined by the required power output, directly impacting battery capacity.
