VRFB energy storage project financing options in Dominican 2026

What is VRFB & how does it work?

The VRFB, which was fully energized in December 2021, is combined with a 50 MW Wärtsilä Li-ion system to form a single hybrid energy storage asset, the largest vanadium flow and Li-ion hybrid system ever deployed.

Who makes VRFBs?

Australian Vanadium Limited, another vanadium producer, also entered the VRFB market through its formation of subsidiary company VSUN Energy. VRFBs are continuing to gain traction for various storage applications due to their durability and advantages providing long-duration energy storage.

Why are VRFBs a promising energy storage technology?

VRFBs are a promising energy storage technology because of their energy storage capacity scalability, full DoD, ability to cycle frequently and for long durations, nonflammable construction, and recyclable electrolyte.

Does China own VRFB?

As the global battery storage market races to secure supplies, VRFB manufacturers are also looking to lock in a strong supply chain. For now, the bulk of vanadium material is owned by China, which could result in a strong reliance on the nation for future large-scale VRFB projects.

How does a VRFB compared to a Li-ion battery affect revenue?

The lower round-trip efficiency of VRFBs compared with Li-ion battery systems can affect revenue for applications such as arbitrage that rely on high margins between the price of energy being discharged and the cost of energy for charging.

When will a VRFB be installed in Japan?

Construction on this VRFB began at the end of July 2020 and is expected to be completed by March 2022. The system will be able to provide 17 MW for up to 3 hours or 51 MWh of energy capacity and will serve the grid from April 2022 to March 2043. The installation is part of the phase-one grid expansion plans for the northern region of Japan.
