What’s the world’s largest flow battery?

175MW/700MWh vanadium redox flow battery project completed by Rongke Power – World’s largest vanadium flow battery

• • As of December 2023, the world’s largest flow battery is a 175MW/700MWh vanadium redox flow battery (VRFB) system developed by Rongke Power in Ushi, China. This project exceeds the company’s earlier installation in Dalian (100MW/400MWh) and marks a significant advancement in global long-duration energy storage (LDES) capabilities.
  • The Xinhua Ushi ESS Project, also referred to as the Ushi project, utilizes 4-hour Vanadium Redox Flow Battery (VRFB) technology. It supports key functions like grid forming, peak shaving, frequency regulation, and integrating renewable energy, crucial for enhancing grid stability in areas with a high share of renewables.
  • The Ushi VRFB project sets new benchmarks in size while addressing the critical need for safe, long-duration energy storage in areas rapidly advancing their clean energy goals.
  • While flow batteries face higher capital costs than lithium-ion systems, they are better suited for applications demanding long cycle life, non-flammability, and deep discharge capability. Rongke’s success demonstrates China’s global leadership in deploying large-scale, commercially viable LDES projects.

Vanadium, a critical component in Rongke’s flow battery systems, requires specialized mining and processing equipment. CAMAL Group supports this supply chain through its mining machinery solutions, enabling efficient extraction and production across Africa and Asia.

Do flow batteries have a future?

Vanadium flow battery from Rongke Power

Flow batteries are gaining traction thanks to significant market growth, technical advantages in long-duration storage, and projected cost reductions; while upfront costs, efficiency challenges, and material supply risks remain, advancements in chemistry and manufacturing position them well for a future as critical enablers of renewable grid stability and clean energy scalability.

Market Growth & Demand

The global flow battery market was valued at around USD 961 million in 2023 and is projected to reach USD 2.72 billion by 2032, growing at a CAGR of 12.9%, driven by rapidly expanding renewable energy deployment and grid-scale storage needs.

Key Advantages for Long-Duration Storage

Flow batteries excel in long-duration energy storage, offering scalable energy capacity decoupled from power capacity and low degradation over thousands of cycles, making them ideal for multi-hour renewable capacity firming.

Cost & Technology Trends

According to the U.S. Department of Energy, innovations in electrolyte chemistry and production are expected to reduce the levelized cost of storage (LCOS) from about $0.16/kWh today to $0.052/kWh by 2030, significantly enhancing commercial viability.

Challenges & Remaining Barriers

Despite progress, barriers include high upfront capital costs, efficiency limitations (60–80%), and critical materials supply chain risks, particularly from vanadium sourcing.

Outlook & Strategic Positioning

With forecasted CAGR above 20% through 2030, strong interest in grid resilience, and emerging policy backing (e.g., Australia’s flow battery factory initiative), flow batteries are positioned as a key player in long-duration renewable integration and climate goals.

What’s the life span of a flow battery?

Range Power – Leading Vanadium Flow Battery (VFB)

Vanadium Redox Flow Batteries (VRFBs)

• • Demonstrated cycle durability of 12,000–20,000 cycles, equating to 10–20 years of operational life.
  • Leading vendors like Invinity have engineer systems for 25+ years, with some versions now rated for 30 years.

Iron Flow Batteries (Fe-RFBs)

• • Commercial systems exceed 10,000 cycles, with projected lifetimes of over 20 years.

Emerging Liquid Flow Chemistries

• • Alkaline sulfur liquid batteries and advanced organic variants show promising lifespans in the 20–30 years range

Which one is better: lithium-ion or flow battery?

VRB Batteries vs Lithium-on: Key Differences Explained

For stationary, long‑duration energy storage, where longevity, safety, and scalable capacity matter more, flow batteries—particularly vanadium or iron variants—outperform lithium‑ion in total cost of ownership and reliability.

• • Cycle life & longevity

Flow batteries (especially vanadium or iron‑based) can deliver 15,000–20,000 cycles and remain viable for 20–30 years, with minimal degradation. In contrast, lithium‑ion systems typically last 5–10 years or 500–1,500 cycles before significant capacity loss occurs.

• • Safety & environmental profile
    Flow batteries use non‑flammable, water‑based electrolytes with low fire risk and stable thermal operation. Lithium‑ion chemistries, while improving, still pose flammability and thermal runaway risks; mining and disposal also raise environmental concerns.

For space‑limited, power‑dense applications like EVs or laptops, lithium‑ion remains the superior choice.

• • Energy density & portability
    Lithium‑ion batteries offer high energy density (150–275 Wh/kg), making them ideal for applications with tight space and weight constraints, such as EVs and portable electronics. Flow batteries, by contrast, have much lower energy density and require large, stationary tanks, making them impractical for mobile use.
  • Cost dynamics
    Lithium‑ion benefits from mature production, resulting in lower upfront costs and high energy efficiency (85–95 %). Flow systems exhibit higher initial capital expenditure and lower round‑trip efficiency (50–80 %), but their long lifespan and scalability can drive down the levelized cost for long‑duration storage.
