Advancing Non-PFAS Ion Exchange Membranes for Green Hydrogen

Ion exchange membranes sit at the center of green hydrogen production, yet many executive teams underestimate how deeply material choices shape cost structures, safety profiles and long-term scalability. Proton exchange membrane systems currently dominate commercial deployment. Their performance is proven, but they rely on PFAS-based materials and precious metals such as iridium and platinum, alongside titanium hardware. Environmental scrutiny around PFAS and volatility in critical mineral supply chains place pressure on developers, electrolyzer manufacturers and investors to reassess their technology stack.

Anion exchange membranes offer a credible alternative. By operating in an alkaline environment, they open the door to less expensive catalysts and stainless-steel hardware while meeting performance targets. That shift has implications not only for capital expenditure but for the overall economics of hydrogen production. At the same time, liquid alkaline systems that use porous diaphragms introduce hydrogen back diffusion and compression challenges, creating safety and efficiency concerns that limit their appeal in modern installations.

Executives evaluating membrane partners must look beyond laboratory data and focus on three underlying realities. Material chemistry now carries regulatory and reputational risk. Non-PFAS pathways are no longer a niche preference but an emerging expectation across clean energy supply chains. The ability to demonstrate environmental alignment without compromising electrochemical performance is increasingly tied to project financing and government support.

Manufacturing scale is equally decisive. Many anion exchange membrane developers remain at small production volumes, leaving customers exposed to higher costs and supply uncertainty. A viable partner must show a credible path to scaling output and lowering unit cost over a defined horizon, not merely pilot-scale validation. Commercial adoption depends on membranes that are accessible in quantity, not just technically promising.

Platform flexibility also matters. Green hydrogen developers often diversify across electrolyzer architectures or adjacent technologies such as fuel cells, carbon capture or flow batteries. A membrane supplier built around a single chemistry for a single use case limits strategic options. A unified material platform capable of supporting multiple membrane types reduces qualification cycles and simplifies long-term procurement strategies.

Orion Polymer positions itself directly within these pressures. It focuses on non-PFAS ion exchange membranes for clean energy applications, offering anion exchange membranes as an alternative to PFAS-based proton exchange systems. Its approach leverages a shared hydrocarbon material platform that extends across anion exchange membranes, hydrocarbon proton exchange membranes and ion-solvating membranes. That common base is intended to support scalability and cross-application use in hydrogen, fuel cells and related clean energy technologies.

Industry validation has begun to follow. Global electrolyzer manufacturers and fuel cell automotive companies have tested and confirmed its membrane performance. A notable example is its selection as an anion exchange membrane supplier in a 2024 U.S. Department of Energy funding application led by a global electrolyzer company. Orion Polymer’s stated objective is to expand production capacity over the next several years, reduce cost through scale and broaden its portfolio to address liquid alkaline and proton exchange systems under a unified non-PFAS framework.

For executives prioritizing environmental compliance, cost discipline and long-term platform flexibility in hydrogen programs, Orion Polymer stands out as a focused and strategically aligned membrane partner.
