A flow battery is a form of rechargeable energy storage technology that uses liquid electrolytes stored in external tanks. They are ideal for large-scale applications, including as grid energy storage, due to their ability to discharge for extended periods of time. Flow batteries are more efficient, last longer, and have greater energy capacity flexibility.

Flow batteries offer several technical advantages over traditional rechargeable batteries with solid electroactive materials. These include the ability to independently scale power (dictated by the size of the stack) and energy (determined by the size of the tanks), extended cycle and calendar life, and the potential for a lower total cost of ownership. Supporting this growth, notable projects like the 400 MWh, 100 MW vanadium flow battery that began operations in Dalian, China, in 2022 the largest of its kind at the time demonstrate the scalability and viability of flow battery technology for large-scale energy storage, further driving market adoption.

Flow Battery Market Report Coverage

Flow Battery Market Insights

The transition to renewable energy sources like solar and wind has created a need for efficient energy storage. For instance, according to International Energy Agency (IEA), renewable energy consumption across the power, heat, and transport sectors is expected to grow by nearly 60% from 2024 to 2030 in main-case forecast. This growth will raise the share of renewable in total energy consumption to almost 20% by 2030, compared to 13% in 2023. The expected growth in renewable energy consumption, particularly in the power, heat, and transport sectors, will drive the demand for flow batteries, as they offer efficient, long-duration storage solutions to balance intermittent renewable generation and ensure grid stability.

As power grids incorporate more intermittent renewable sources, grid stability becomes crucial. For instance, the U.S. electric grid is featuring over 9,200 power generation units with a combined capacity exceeding 1 million megawatts, all linked by more than 600,000 miles of transmission lines. Due to the growing complexity of the electric grid and the need for reliable energy storage solutions, the demand for flow batteries is expected to rise as they provide long-duration storage to enhance grid stability.

The upfront costs associated with flow battery systems can be a significant barrier to widespread adoption. While their long-term benefits are clear, the capital required to deploy these systems is often higher than other storage solutions. This cost challenge can hinder adoption, especially in developing markets.

With the rise of electric vehicles, there is an increasing need for reliable and scalable energy storage solutions at EV charging stations. For instance, International Energy Agency states that in 2023, nearly 14 million new electric cars were registered worldwide, bringing the total number of electric vehicles on the road to 40 million, in line with the sales forecast from the 2023 Global EV Outlook (GEVO-2023). Electric car sales in 2023 were 3.5 million higher than in 2022, marking a 35% year-on-year growth. This increase is more than six times the number of sales in 2018, just five years prior. This presents a promising market for flow battery applications.

With the growing adoption of EVs, the proportion of charging from private and public charging stations (measured by electricity delivered to vehicles) is projected to increase over time. By 2035, nearly 45% of electricity for EV charging is expected to come from sources other than home chargers, up from less than 35% in 2023. As the expansion of public and private EV charging infrastructure requires scalable and efficient energy storage solutions to manage high-demand charging loads drives growth of flow battery market.
