Breakthrough in Flow Battery Component Manufacturing
TreadStone Technologies Inc. has achieved a major milestone in the commercialization of long-duration energy storage components. The company has officially advanced into Phase 3 of a U.S. Department of Energy (DOE)-funded program. This phase focuses on significantly cutting the cost of flow battery electrodes and bipolar plates by up to 53%. The cost reduction is made possible by TreadStone's proprietary carbon coating technology, known as DuraC, which enhances the durability and performance of critical battery components.
Validation Across Multiple Battery Chemistries
The versatility of the DuraC coating is one of its most significant advantages. The technology is currently being validated across a wide range of flow battery chemistries, including zinc-bromine, all-iron, and aqueous organic systems. By providing a universal solution that improves component longevity and reduces manufacturing costs, TreadStone is addressing one of the primary barriers to the widespread commercial deployment of various long-duration energy storage technologies.
Independent Testing at Pacific Northwest National Laboratory
As a critical component of Phase 3 commercialization, TreadStone is actively building a complete flow battery system. This system will undergo rigorous independent testing and validation at the prestigious Pacific Northwest National Laboratory (PNNL). The validation process at PNNL will provide unbiased, third-party verification of the DuraC coating's performance, durability, and cost-saving claims. Successful completion of this testing phase will pave the way for large-scale manufacturing and integration into commercial grid-scale storage projects.
Reducing the cost of electrodes and bipolar plates by over 50% is a game-changer for flow batteries, bringing long-duration energy storage closer to cost parity with traditional grid infrastructure.
