Redox Flow Battery Technology Trend and Market Forecast (~2025)




As eco-friendly renewable energy sources, such as wind power, solar PV, etc., have recently spread, the High Capacity Energy Storage System (ESS) market is receiving attention in storing the electric energy produced here, and the Redox Flow Battery technology, one of the batteries that can store energy, is also developing together.


Unlike the conventional lead & lithium-based batteries, the Redox Flow Battery is a system where the active material in a water-soluble electrolyte made of liquid is oxidized/reduced and then charged/discharged, which is an electrochemical capacitor that directly stores the chemical energy of the electrolyte as electrical energy.


Currently, pumping-up power generation and others among ESS applications are widely used, but due to problems, such as costs, geographical constraints, environmental destruction, etc., Redox Flow Batteries have recently emerged as an alternative, whose prospects are quite bright as researches to improve the energy efficiency, their disadvantage, are being continuously conducted.


The Flow Battery can cope with the markets from the KWh-class small size to MWh-class large size and has the strength of having a long life of 20 years. Furthermore, the fact that its Energy and Power is separated could be a great advantage, but because only small production at the project level and demonstration projects are underway so there is no mass production line unlike rival technologies including LiB and ALAB, reducing costs and securing mass production technologies is also now insufficient. In addition, owing to the upsurge in prices of the raw material vanadium in 2019, there are difficulties in securing price competitiveness, compared to LiB, the rival technology.


In contrast with this, in the case of LiB which is its rival technology, mass production technology has been matured because large companies, such as LG, Samsung, CATL, etc., which have large-scale mass production lines, are participating in the ESS market; as the price drop continues to occur due to this, it is acting as the biggest obstacle to the entry of the Flow Battery into the market. However, because fire accidents have continuously occurred in ESS where LiB is applied since 2019, for Flow Batteries, now could be the best opportunity to enter the market, as it is the time point that the market demand for a high-safety secondary battery that can replace this is increasing. SNE Research has explored the installation performance, current status of major companies, and technical challenges to be solved for Redox Flow Batteries, up to the recent date, and forecasted the mid- to long-term market until 2025.
