HOBE ENERGY Unveils HOBEFLOW-200

HOBE ENERGY, a pioneering company in next-generation energy storage solutions, is set to launch its revolutionary vanadium redox flow battery (VRFB), named HOBEFLOW-200, on October 22, 2025. This advanced battery integrates essential safety features alongside a 20+ year design lifespan, making it ideal for applications requiring extended discharge times exceeding six hours. Furthermore, it provides excellent lifecycle cost efficiency for long-term energy solutions, aiding stability in renewable energy supply and enhancing grid resilience.

Development Background of HOBEFLOW-200

As the integration of renewable energy sources accelerates, the demand for storage solutions that can accommodate variable generation has increased. The existing lithium-ion batteries predominantly handle short-duration applications, leaving a gap for solutions that can operate consistently for more than six hours. This is where HOBE ENERGY steps forward with its newly designed VRFB, tailored for both domestic and international long-duration energy needs. Our effort has focused on optimizing a module that delivers longevity, high-frequency operation, and intrinsic safety—positioning it as the go-to “infrastructure battery” for future energy demands.

Key Features of HOBEFLOW-200

1. Intrinsic Safety: The non-flammable aqueous electrolyte eliminates the risk of thermal runaway and associated fire risks, offering peace of mind for critical infrastructure and urban sites.
2. Longevity and Durability: Designed for over 20 years of operation with minimal electrolyte degradation, the HOBEFLOW-200 maintains high capacity through frequent cycling, significantly reducing the need for mid-life replacements (repowering).
3. Economic Viability: With independent optimization of output (kW) and capacity (kWh), it excels in longer discharge scenarios in terms of Levelized Cost of Storage (LCOS), particularly beneficial for nighttime renewable energy transfer and sustained peak loads.

Anticipated Deployment Scenarios

• - Grid Storage Facilities: Ideal for long-duration operations (6–12 hours) and base energy storage for frequency regulation.
• - Large-Scale Renewable Energy Integration: Optimizing selling electricity from daytime to night, with flattened output variability.
• - Industrial Facilities: Equalizing continuous peak loads and providing extended backup for business continuity plans (BCP).

Comments from HOBE ENERGY President Koichi Okino

"HOBEFLOW-200 has been designed for customers prioritizing long-term reliability over immediate cost savings. Our focus on safety, durability, and economic efficiency during long durations is key in navigating the next challenges for stable renewable energy supply."
