High Performance Cation Exchange Media

The Department of Energy, through its contractor Fluor Marine Propulsion (NNL), is seeking information on high-performance cation exchange media with enhanced thermal stability. This requirement addresses the limitations of traditional mixed-bed organic resins, which are currently restricted by an anion resin thermal stability limit of 140°F. The goal is to identify or develop cation media capable of maintaining normal operations at temperatures of 250°F or higher at saturation pressure. Prospective offerings must demonstrate a total mixed-bed ion exchange capacity greater than 0.8 milliequivalents per milliliter and maintain low solubility in dilute alkaline solutions at elevated temperatures.

Solicitation NNL-FMP-0045 requires descriptions of modifications to typical organic resin chemistry and structure or the introduction of new materials that meet the specified performance metrics. Selected materials will undergo testing for cation exchange capacity, physical integrity, and solubility across various temperatures and durations. This research and development effort is classified under PSC AG12 for Energy R&D Services; Energy Supply; Applied Research and is associated with NAICS code 541715 for Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology).

The performance of these services will take place within the United States. Technical inquiries and questions are scheduled for a four-week period following the initial publication, with point of contact support provided by ATIP, Cognizant Scientist John Arnason, and Cognizant Manager Cassandra Dickson. The response deadline for this solicitation is March 17, 2026. No additional attachments are associated with this notice at the time of publication.
