Global Flow Battery Market - Share, Size, Growth, Trends, and Outlook to 2028

Flow batteries have been gaining significant traction in recent years, driven by a variety of factors, such as the growing energy storage solutions market owing to the renewable energy integration into the grid , grid modernization, and the rising need to enhance grid reliability. It is anticipated that these drivers will continue to fuel the expansion of the flow battery market during the forecast period, with the Asia Pacific and Middle East regions offering significant growth opportunities.

Even though there is substantial room for expansion in the global flow battery market, there are a number of factors that could potentially stunt that expansion. The high cost, the low energy density, the lack of standardization, the competition from other energy storage markets and the availability of raw materials are some of the primary factors restraining the worldwide flow battery market growth.

What are Flow Batteries?

Flow batteries, also known as redox flow batteries, are a type of rechargeable battery that uses two chemical components dissolved in electrolyte liquids to store energy. Unlike conventional batteries, flow batteries can store an unlimited amount of energy by simply adding more electrolytes.

The main advantages of flow batteries include -  

• Easy scalability and design flexibility
• Increased safety
• Longer asset life (decades)
• Less concern with ambient temperature 
• Lower levelized cost of storage (LCOS)
• High round-trip efficiency (RTE)
• Depth of discharge (DoD)
• Negligible environmental impacts

Growing Demand for Energy Storage Solutions

The demand for energy storage systems is rapidly increasing as governments and organizations around the world seek to accelerate the adoption of renewable energy sources. This is in line with their commitment to achieving emission reduction targets and fulfilling ESG (environmental, social, and governance) objectives.

This growing demand for energy storage systems is significantly influencing and propelling the flow battery market. As governments and organizations increasingly turn to renewable energy sources, they will require efficient and reliable means of storing and managing the electricity generated. Flow batteries, with their ability to store large amounts of energy over extended periods, are well-positioned to meet this demand and play a pivotal role in supporting the expansion of renewable energy adoption.

Governments worldwide are actively implementing incentives and supportive regulations to encourage the widespread adoption of renewable energy sources. In regions with the highest energy consumption, such incentives are particularly robust, promoting a shift away from conventional energy options. In Europe, the impetus for renewable energy adoption is driven by the ongoing energy crisis, while in the United States, the recent Inflation Reduction Act of 2022, which earmarks USD 370 billion for clean-energy investments, serves as a major driver for these efforts. 

Battery storage is a critical facilitator for the integration of renewable energy generation, ensuring a consistent and reliable energy supply despite the inherent intermittency of renewable sources. The versatility of battery energy storage systems (BESS) positions them as a crucial component for various applications, including optimizing peak power usage, enhancing self-consumption efficiency, and providing reliable backup power during outages. The distinctive benefits offered by flow batteries, including scalability, flexibility, extended asset lifespan, safety features, and more, render them an excellent choice for renewable energy storage solutions.

Segment Analysis 

The market for redox flow batteries is currently dominated by vanadium redox flow batteries (VRFB), one of the many different forms of redox flow batteries, due to factors such as high efficiency, long lifespan, scalability, safety, and availability of raw materials. The electrolyte in VRFBs is a solution of vanadium ions in different oxidation states. This allows for reversible electrochemical reactions to take place, which is necessary for the storage of energy.

Hybrid flow batteries and other types of redox flow batteries are also gaining traction.
