BESSt Unveils Revolutionary Redox Flow Battery With 20x Higher Energy Density
US-based startup BESSt has unveiled a revolutionary redox flow battery technology, boasting an energy density 20 times higher than conventional vanadium systems. The innovation, set to launch in the commercial and industrial market, promises enhanced reliability and safety for government, critical infrastructure, and industrial users.
At the heart of BESSt's new system lies a key innovation: an electrolyte made with zinc-polyiodide (ZnI2), developed by the U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL). This technology, combined with a 'patent-pending' cell stack using unspecified 'earth-abundant' alloy materials sourced in the United States, sets BESSt's battery apart.
The battery is designed for easy deployment alongside solar, with a compact footprint and effectiveness for both hybrid renewable systems and standalone stationary storage. It offers extended-duration storage without degradation, making it well-suited for solar and other renewable projects.
BESSt's residential launch is planned for early 2028, expanding the technology's reach. While the specific developers of the patent-pending zinc-polyiodide electrolyte technology remain unclear, the company's advancements promise a significant leap in energy storage capabilities.
