EDG exclusively distributes The BESSt Company’s zinc polyiodide (ZnI₂) REDOX flow battery technology. This chemistry is licensed from Battelle. It offers non-flammable, non-toxic energy storage using earth-abundant materials sourced from the U.S. and allied nations.

Unlike lithium-ion batteries that store energy in solid electrodes, REDOX flow batteries store energy in a liquid electrolyte. This means energy capacity (kWh) and power output (kW) can be scaled separately—simply add more electrolyte for longer runtime or more stacks for higher output.

• Safety: Non-flammable and non-toxic (no thermal runaway risk).

• Scalability: Energy and power can be scaled independently.

• Longevity: Electrolyte lasts 20+ years, with a 30-year system warranty.

• Energy Density: Up to 20× higher than vanadium flow and 3× some lithium-ion chemistries.

• Cost Advantage: DOE-aligned roadmap to sub-$0.05/kWh-cycle by 2030.

The round-trip efficiency is 75–80%, with lab validation complete and field validation underway.

• Electrolyte life: 20+ years

• System warranty: 30 years

• No performance loss from 100% depth of discharge

• Cold weather: Performs well due to aqueous chemistry.

• Thermal stability: Very stable, no overheating risk.

• Self-discharge: Very low, meaning the battery holds charge longer.

• Proven, patent-pending technology with Battelle backing

• Safe chemistry—no hazmat transport or fire suppression required

• Long product life reduces service calls and warranty claims

• Small footprint allows placement in dense urban or space-limited locations

• Scalable for residential, commercial, industrial, and utility use

• Grid & Utility: Renewable firming, peak shifting, transmission & distribution deferral

• Commercial & Industrial: Demand-charge reduction, backup power

• Renewable & Microgrids: Solar/wind smoothing and off-grid systems

• Residential: Whole-home backup (pending policy adoption)

The BESSt Company uses a design-for-manufacturing (DFM) approach with:

• 3D-printed tooling for rapid iteration

• Contract-manufactured sub-components

• Final U.S. assembly

• Modular design for easy scaling

• Regional suppliers to reduce risk and lead times

When looking only at upfront costs, lead-acid batteries often appear cheapest. However, they typically last only 3–5 years before needing replacement, and they require frequent maintenance, which drives up the total lifetime expense. Lithium-ion batteries have a higher purchase price — often 30–50% more than lead-acid — and last about 8–10 years. While they offer better performance, they still degrade over time, can present safety risks such as thermal runaway, and carry high recycling costs.

The BESSt Company batteries are priced competitively with lithium-ion systems but last 20+ years with little to no performance degradation. They require virtually no maintenance and use a safer chemistry that avoids the costly disposal and safety issues associated with other types. Over the life of the system, The BESSt Company batteries deliver one of the lowest cost-per-kilowatt-hour figures in the industry, making them not only a cleaner choice but also the most economical for long-term energy storage.

The combination of safety advantages, long lifespan, scalability, and favorable cost trajectory positions zinc polyiodide REDOX flow batteries as a strong alternative to lithium-ion and vanadium, especially in long-duration stationary storage markets. Distributors can tap into utility, industrial, and renewable integration projects with high-margin, high-demand solutions.
