Problem
Industrial and agricultural sites often rely on diesel generators or limited grid connections for backup power, leading to high fuel costs, emissions, and fire risk. Existing stationary battery solutions, such as lithium‑ion systems, can be expensive, have safety concerns, and lack easy scalability for varying power and energy needs.
Solution
Wolf Batteries offers water‑based stationary flow batteries that store energy in liquid electrolytes composed of iron and organic molecules derived from bio‑waste. The flow‑battery architecture separates power (stack size) from energy (tank volume), allowing operators to scale capacity by adding tanks without redesigning the system. The electrolyte is fire‑proof, low‑toxicity, and made from earth‑abundant materials, providing a safe, long‑life alternative to lithium‑ion and diesel solutions. Energy is stored by pumping the liquid through a stack during charging and reversed during discharge, enabling low self‑discharge and high round‑trip efficiency. The system can be installed underground or onsite, supporting renewable integration such as solar‑powered EV fleets, dairy farm cooling, or data‑center backup.
Target Audience
Primary customers include dairy farms, business parks, EV logistics operators, and data‑center owners seeking reliable, low‑cost, and safe stationary energy storage.
Features
