Electrolyzers

Green hydrogen is the backbone of net-zero. PEM electrolyzers are its engine. TreadStone protects the stack.

Green hydrogen production via water electrolysis is on the cusp of industrial-scale deployment. The shift away from steam methane reforming (SMR) — which has historically produced 90% of global hydrogen — is accelerating under government mandates, corporate net-zero commitments, and falling renewable energy costs.

PEM and alkaline electrolyzers both play significant roles in the green hydrogen landscape. Alkaline systems are well-established, cost-effective at scale, and widely deployed. PEM systems are gaining ground rapidly, driven by higher energy efficiency, faster dynamic response to variable renewable inputs, and higher-purity hydrogen output. As PEM deployments scale, the demand for corrosion-resistant, electrically conductive coatings on titanium and stainless steel components is becoming a first-order engineering constraint — one TreadStone is built to solve.

PEM electrolyzers are extraordinarily demanding on their metal components. The combination of high voltage, acidic electrolyte, and elevated temperatures creates a corrosive environment that degrades uncoated titanium and stainless steel components rapidly — driving up replacement costs and reducing system efficiency over time. This is precisely the challenge TreadStone was built to solve.

TreadStone's coating technologies have been independently tested and validated through U.S. Department of Energy-sponsored programs for PEM electrolyzer applications — demonstrating superior protection of metal substrates against corrosion while maintaining electrical conductivity that outperforms competitors. These are production-ready coatings with a performance record built through rigorous DOE-funded testing, available for integration into your electrolyzer manufacturing program now.

TreadStone coatings reduce hydrogen production costs by lowering contact resistance across the cell stack, extending component service life, and minimizing H2 uptake into the metal substrate over time. Our DOT coating is the leading choice for titanium-based PEM electrolyzer components, delivering industry-benchmark protection against hydrogen impregnation and long-term corrosion — backed by test data that documents performance at every point of the degradation curve.
