Market Trends of Europe Flow Battery Industry
Vanadium Redox Flow Batteries are Expected to Witness Significant Growth
- A vanadium redox flow battery (VRFB) is a redox flow battery (RFB) that stores energy by using V2+/V3+ and V4+/V5+ redox couples of vanadium in the negative and positive half-cells, respectively. The power ratings and energy ratings of these batteries are not related to each other, and each can be optimized for a different type of use.
- The advantages of using vanadium redox flow battery (VRFB) over other flow batteries are higher specific energy and power, a very long lifespan with up to 20,000 charge and discharge cycles, a reduced levelized cost of energy, and no problems with overcharging and deep discharge.
- Furthermore, vanadium redox flow batteries (VRBs) are promising energy storage systems suitable for large-scale solar-battery integrated electric vehicle charging stations. Thus, these batteries are of significant use in EV industry.
- According to the European Environment Agency, in 2023, the share of electric cars accounted for 23.6% of the total cars in Europe, increased from 21.6% share in 2022. Thus, with an increase in the percentage of EVs, the use of these batteries in EVs is expected to be in demand, thereby driving the market's growth.
- Moreover, with technological developments to increase the efficiency of vanadium redox flow batteries, the use of these batteries is expected to increase during the forecast period. For example, in March 2024, Enel Green Power installed 1.1 MW/5.5 MWh vanadium redox flow battery in its Son Orlandis solar PV plant in Spain.
- Thus, owing to the advantages of using these batteries, along with research and development activities, vanadium redox flow batteries are expected to witness significant growth.

The United Kingdom is Expected to Witness Significant Growth in the Market Studied
- The United Kingdom witnessed significant growth in the demand for flow batteries in recent years, particularly after 2021, with a number of projects coming online and proposed to come online in the near future.
- Flow batteries can be used in an integrated ES system to store renewable energy. The country's renewable energy capacity has been increasing consistently, creating a positive scope for the flow battery market. According to the International Renewable Energy Agency, as of 2023, the total capacity installed by the UK renewable energy industry accounted for 55,561 MW, an annual growth rate of 4.7%.
- In May 2024, the UK Infrastructure Bank announced EUR 25 million (~USD 27 million) investment into Invinity Energy System Plc to develop next generation vanadium flow battery products. Furthermore, in January 2023, StorTera Ltd developed a single liquid flow battery that combines the advantages of lithium-ion technology and a long-duration renewable energy storage system.
- Moreover, in April 2023, Invinity Energy Systems PLC announced that it received EUR 11 million (~USD 11.88 million) in funding from the Department for Energy Security and Net Zero under Phase 2 of the Longer Duration Energy Storage Demonstration Competition. Using the funds, the company will deploy a 30 MWh vanadium flow battery, the UK's largest flow battery, and Invinity's largest delivery.
- Overall, owing to the above projects, the country is expected to witness significant growth in the demand and supply of flow batteries, mainly driven by increasing investments in the sector combined with increasing research and development.
