Orion Polymer Corp’s polymers and membranes are a collaborative commercialization between the RPI, Rensselaer Polytechnic Institute, Chemistry Dept and Xergy Inc, a leading producer of membranes. Orion’s patented polymers are superior in performance to all other ionomers as reviewed in an independent study by NREL, the National Renewable Energy Laboratory, Golden Co. (See Meek, et. al. 2019).

Orion Polymer is a leading provider of ion exchange polymer resins and solutions that deliver unmatched performance, stability, and durability for advanced composite membranes. As a supplier of both anionic and cationic polymers, Orion Polymer has the ability to design, produce, and support a virtually unlimited range of polymer-based ion exchange solutions.

As clients’ needs evolve, Orion Polymer can custom-synthesize its resins and solutions effectively tailoring its products to specific projects and applications. This customization includes everything from the ionomer’s functional group to its intrinsic properties including strength and stability. Correspondingly, with its strategic relationship with Xergy Inc., Orion Polymer can also deliver made to order synthesized membranes (XION™) that offer ultra-thin, ultrastrong, and ultra-high ionic transport capabilities that can be leveraged to support the customized development of a virtually unlimited array of innovative technologies.


Orion Polymer represents a strategic partnership between Xergy Inc., one of the nation’s top innovators in the advanced energy solutions sector and Dr. Chulsung Bae, a leading expert in ionic polymer chemistry and advanced materials science.

Chulsung Bae, Ph.D.

Dr. Bae is currently a professor of chemistry at Rensselaer Polytechnic Institute (RPI). Dr. Bae received a Ph.D. in chemistry at University of Southern California in 2002 under the guidance of G. K. Surya Prakash and Nobel Laureate George A. Olah. After postdoctoral research with John Hartwig at Yale University, he started independent academic career at University of Nevada Las Vegas (UNLV) as an Assistant Professor in 2004. In 2012 Bae relocated his research group to RPI where he is currently a professor at Department of Chemistry & Chemical Biology. Dr. Bae received a number of awards including New Investigator Award of UNLV (2005), National Science Foundation CAREER Award (2008), and RPI School of Science Outstanding Research Award (2016).

In 2017 Dr. Bae received a $2.2 million in funding from the U.S. Department of Energy’s Advanced Research Products Agency-Energy (ARPA-E) to develop innovative solid ion conducting materials for next generation renewable energy conversion and storage technology.

Introducing Anion Exchange Polymer from Orion Polymer: OrionTM1

Non-technical description of OrionTM1

While cation exchange polymers and membranes have been available for over 30 years, there are limited sources for anion exchange polymers and membranes, slowing the development of new, transformational electrochemical technologies that can deliver clean energy solutions at reduced costs.

Orion Polymer is introducing a new class of anion exchange polymers (available as ionomer solution, polymer membrane, and reinforced composite membrane) that can perform as a separator and solid electrolyte in a variety of electrochemical energy conversion technologies such as fuel cells, electrolyzers, and flow batteries.

OrionTM1 provides selective transport of anions (including OH–) across the membrane and electrodes in electrochemical cells, while offering excellent chemical stability in alkaline conditions and tough mechanical properties.

Orion Polymer will enable you to develop your technologies with high-performance, stable polymers.

Technical description of OrionTM1

OrionTM1 is an aromatic polymer containing alkyltrimethylammonium cation groups which exhibits excellent chemical stability in alkaline conditions, tough mechanical properties, good ion conductivity, low water swelling, and good solubility in a variety of solvents including alcohol/water mixtures.

OrionTM1 is available in isopropyl alcohol/water solution, polymer resin, and 20 µm composite membrane forms.
