Clean Energy Driving the Uptake of Ion Exchange Membranes

Ion exchange membrane materials are electrically conductive materials responsible for the selective transportation of ions, and are necessary for applications including green hydrogen production, hydrogen fuel cells, and carbon capture. IDTechEx's report, "Ion Exchange Membranes 2025-2035: Technologies, Markets, Forecasts", covers the latest developments in the sector, with the market expect to surpass US$2.9B each year by 2035.

 

 

Ion exchange materials are renowned for their ion and electrical conductivity, their light weight, and ability to be integrated with electrodes in membrane electrode assemblies. They come in the form of polymer sheets or films that are porous and made from hydrocarbon or fluoropolymer materials and have the option to be reinforced using synthetic fabrics or a multilayer approach, which will create higher mechanical stability durability.

 

The Ion Exchange Membranes report outlines some other key innovations in ion exchange composition and manufacturing alongside reinforcement. These include tuning ionomer chemistry for better conductivity, composite membranes to improve mechanical strength, co-extrusion for simplified production processes, stretching for reduced thickness, and ultrathin membrane technology for maximized ion conductivity. The introduction of ultrathin membranes will also allow for a higher cell count in fuel cell and electrolyzer stacks for increased power density. These innovations will all allow for enhanced performance and extend the lifetime of integrated products.

 

 

Worldwide, there are some major trends impacting the applications for ion-exchange membranes. With sustainability and decarbonization being at the forefront of many developing materials technologies, the market for this technology is no different. In emerging applications such as hydrogen fuel cells and water electrolyzers, the uses for ion exchange membranes are increasing in line with energy decarbonization efforts across many industries. As clean energy production is more prevalent than ever, off-grid power and carbon emissions reductions are being prioritized, outlined within IDTechEx's reports, "Stationary Fuel Cell Markets 2025-2035: Technologies, Players & Forecasts" and "Materials for Green Hydrogen Production 2026-2036: Technologies, Players, Forecasts".

 

Amongst transportation and climate change initiatives, ion exchange membranes are also making a name for themselves, emerging into new markets including hydrogen fuel cells and CCUS. Technologies such as proton exchange membrane fuel cells (PEMFCs) in hydrogen fuel cell EVs aim to reduce emissions while driving by only producing water vapour as a byproduct. For CO₂ electrolyzers for carbon capture and utilization, ion exchange membranes are also up-and-coming as a high value technology. Direct air capture, direct ocean capture, and electrosynthesis processes are some of the technologies whose efficacy will also be benefited by the uptake of ion exchange membranes. IDTechEx's reports, "Fuel Cell Electric Vehicles 2025-2045: Markets, Technologies, Forecasts" and "Carbon Capture, Utilization, and Storage (CCUS) Markets 2026-2036: Technologies, Market Forecasts, and Players", further aim to highlight the significance of ion exchange membranes within the current global decarbonization market.

 

Within other emerging applications such as redox flow batteries, ion exchange membranes are necessary amongst all iron and vanadium RFBs, zinc-bromine RFBs, and organic RFBs. IDTechEx's report, "Redox Flow Batteries Market 2026-2036: Forecasts, Markets, Technologies and Players", goes into further detail.
