🔬 Why EZBattery is Essential for the Industry
Flow batteries have long been recognized for their potential to deliver scalable, long-duration energy storage. However, their development has been slowed by the need for extensive physical testing to optimize performance and lifespan. The EZBattery Model, developed with DOE funding, solves this challenge by:
Accelerating Development: Reducing simulation times from days to under a second.
Providing Precision: Offering physics-based insights into intricate battery behaviors, such as solid deposition in hybrid systems.
Enhancing Accessibility: Making advanced tools available through open-source platforms, enabling global collaboration.
💡 Addressing Key Industry Challenges
Traditionally, optimizing flow battery chemistries and architectures required significant time and resources. The EZBattery Model enables researchers to bypass costly prototyping and quickly iterate designs, leading to faster innovation in battery technologies that are essential for scaling renewable energy.
🚀 Flow Batteries as the Future of Energy Storage
Flow batteries, particularly vanadium flow batteries, stand out as best-in-class solutions for long-duration energy storage. Over the past 40 years, vanadium flow batteries have proven their reliability, scalability, and unmatched ability to handle repeated charge-discharge cycles without significant degradation. Their long lifespan, nearly unlimited cycling capability, and ease of scalability make them the gold standard for grid-scale energy storage.
With the EZBattery Model, the DOE is empowering researchers to unlock the full potential of vanadium flow batteries and other advanced systems, ensuring a sustainable and resilient energy future.

The Pacific Northwest National Laboratory (PNNL) has several projects related to flow batteries that are supported by the Department of Energy (DOE), including:
24-hour flow battery
A partnership between PNNL's energy storage researchers and operations and facilities teams, this project will install a vanadium redox flow battery (VRFB) system at PNNL's Richland campus. The battery will be able to sustain critical functions during power outages.
Grid Storage Launchpad (GSL)
This new facility at PNNL will help develop next-generation batteries for grid energy storage. The GSL is funded by the DOE's Office of Electricity.
EZBattery Model
This publicly available software model can simulate individual battery cells and large-scale systems for long duration energy storage.
Long-Duration Energy Storage (ESRA) hub
This DOE investment of up to $62.5 million over 5 years will help identify promising approaches to large-scale energy storage. PNNL will leverage its investments in redox flow battery technology, robotics, and other tools.
Redox flow battery milestones from PNNL and Sumitomo Electric
Flow batteries are designed to store large amounts of energy from renewable sources for long periods. They are made up of two tanks of electrolyte solutions, one for the cathode and one for the anode. Electrolytes pass through a membrane to charge and discharge energy.
