Batteries

$1.2B market by 2027. TreadStone is supply-chain-ready today.

Flow batteries are emerging as the critical long-duration energy storage solution for the global renewable grid — and the market is growing fast. Expenditures are projected to hit $1.2 billion by 2027 at a 12% CAGR from 2022, driven by the urgent need for 4+ hour grid storage that conventional lithium-ion batteries cannot economically provide.

As flow battery manufacturers scale from pilot to commercial deployment, they need a Tier 1 coating supplier who is production-qualified, technically validated, and able to ramp output with them. TreadStone is the coating partner with commercially proven technology, demonstrated production scale, and the application expertise to become a qualified supplier in your program today.

Flow batteries store energy in liquid electrolyte and release it on demand, offering unmatched scalability for grid-level, long-duration storage. Most current flow batteries use graphite-based separators; the transition to metal electrodes reduces system volume (increasing energy density), improves economies of scale (reducing cost), and requires coatings with excellent long-term durability to manage ongoing maintenance costs.

In the long-duration storage market (>4 hours), flow batteries are unrivaled, but cost and component durability remain the primary barriers to broad commercial deployment. Solving the electrode coating challenge is the single most effective lever for bringing flow battery system costs down to grid-competitive levels. TreadStone has solved it.

TreadStone's electrode coatings directly address the two primary cost drivers in flow battery systems: capital cost of the cell stack and long-term maintenance. By applying our electrically conductive, corrosion-resistant coatings to lower-cost electrode materials, system designers can cut Capex without sacrificing performance or service life. Our coatings have been independently tested and proven to deliver significant, measurable cost savings in real-world flow battery stacks.

Through U.S. Department of Energy Advanced Manufacturing and Materials Technologies Office programs, TreadStone has developed and validated its DuraC carbon coating technology for commercial flow battery deployment. TreadStone maintains a strong track record of DOE-sponsored research and anticipates ongoing collaboration as the flow battery market continues to scale. DuraC is electrolyte-agnostic, low-cost, and engineered to maintain peak energy efficiency throughout the full storage cycle. As the flow battery market moves to gigawatt-hour capacity, TreadStone is the production-qualified coating supplier building alongside it.
