In terms of application, electrolysis segment is estimated to contribute the 34.9% share of the market in 2025, owing to benefits it provides over alternative processes. Ion exchange membranes find widespread usage in chloralkali electrolysis for production of chlorine and caustic soda. Compared to mercury cell and diaphragm cell technologies, ion exchange membrane electrolysis cells offer higher energy efficiency and lower capital cost. These allow use of cheaper salt solutions and facilitate co-production. Ion exchange membrane cells are also more environment-friendly with no mercury emissions. Furthermore, ion exchange membranes enable extraction of hydrogen through water electrolysis, which is a key reaction involved in hydrogen production. With growing focus on green hydrogen economy, electrolytic water splitting applications are expected to boost demand for ion exchange membranes. Overall efficiency and cost advantages relative to competition have made electrolysis the leading application segment.
By material, hydrocarbon membranes account for the largest share of the ion exchange membrane market, holding 36.2% in 2025. Their dominance is driven by cost-effectiveness, ease of processing, and broad application across water treatment, energy generation, and separation technologies. Additionally, their use in desalination and wastewater recycling aligns with global initiatives to address water scarcity, further strengthening demand in the coming years.
For instance, June 2025, Imperial College London announced advancements in hydrocarbon-based ion exchange membranes designed for fuel cells and electrolyzers, offering a cost-effective and environmentally sustainable alternative to perfluorinated membranes.
In terms of charge, cation segment is estimated to contribute the 33.9% share of the market in 2025, due to its widespread adoption in water treatment. Cation exchange membranes are used for softening of water by removing calcium and magnesium cations. These find major application in municipal and industrial water treatment plants for producing soft water. Cation exchange also helps to reduce water hardness and total dissolved solids. Given growing freshwater scarcity and stringent drinking water norms, effective water treatment technologies are being increasingly deployed worldwide. This increasing focus on water treatment has propelled the cation segmentgrowth.
By end-use industry, water treatment represents the largest share of the ion exchange membrane market, accounting for a significant portion in 2025. The dominance of this segment is driven by the rising global demand for clean and safe drinking water, coupled with growing investment in desalination plants and wastewater treatment infrastructure. Increasing concerns over water scarcity, particularly in Asia-Pacific and the Middle East, further amplify the need for efficient ion exchange membranes in purification and recycling processes.
For example, in April 2025, Arab News reported that Veolia is positioning Saudi Arabia and the wider Gulf region at the forefront of desalination innovation by advancing membrane-based desalination technologies. The shift from traditional thermal processes to more efficient membrane solutions reflects the company’s strategy to reduce energy use and improve water sustainability in the region.

North America accounted for 25.6% of the global ion exchange membrane market in 2025 and is expected to maintain its leading position over the forecast period. Growth is supported by strong industrial presence across chemical processing, water & wastewater treatment, electrical & electronics, and power generation. The U.S. and Canada, with stable economies and early adoption of advanced technologies, drive demand for innovative membranes. In addition, the presence of leading manufacturers and active R&D initiatives strengthens the region’s dominance.
For instance, September 2024, Industrie De Nora launched the CECHLO-MS 200 ion exchange membrane electrolysis technology for the North American market, establishing a U.S. center of excellence to localize assembly and enhance support for municipal and industrial water treatment applications.
Asia-Pacific represents the fastest-growing regional market for ion exchange membranes, driven by rapid economic development and infrastructure expansion in countries such as China, India, Indonesia, and Vietnam. Rising demand from process industries and strong focus on wastewater treatment and desalination projects accelerate adoption of ion exchange membranes. Furthermore, the availability of raw materials and cost-effective labor continues to attract leading manufacturers to set up production facilities across the region, increasing access to both standard and customized membranes..
For instance, February 2024, Veolia Water Technologies redeveloped a brownfield site in Changshu, China to launch its first ion exchange regeneration facility. This facility will service water purification, industrial deionization and mobile water treatment, regenerate‐and‐recycle ion exchange resins, with ~€10 million investment.
The U.S. remains a key leader in ion exchange membrane technology, driven by clean energy policy support, R&D investment, and strong demand from hydrogen, fuel cell, and water treatment projects.
For instance, August 2025, Advent Technologies entered into an agreement with a U.S.-based global semiconductor and wireless technology company to develop electrochemical gas sensors using its advanced Ion Pair membrane, highlighting the potential of ion exchange membranes in next-generation sensing and medical diagnostics.
China is expanding its role both as a major consumer and producer of ion exchange membranes, particularly through its focus on infrastructure, water treatment, desalination, and green hydrogen programs. There is increasing local capacity to manufacture both generic and customized membranes for regional industrial needs.
For instance, June 2025, Tianhua New Energy debuted a new series of ion exchange membranes at the International Clean Energy Conference and Expo in Tianjin, showcasing high ion selectivity and conductivity membranes designed for energy storage and hydrogen applications, marking a significant domestic technological breakthrough.

Global ion exchange membrane market is expected to witness significant growth due to increasing demand from the water treatment industry. Proper treatment of water is essential before it is supplied for various industrial and municipal purposes. Ion exchange membrane technology is widely being used in desalination plants, wastewater recycling units and purifying brackish water. As the global fresh water reserves are under strain due to rising population and industrialization, more countries are turning to advanced water treatment technologies like reverse osmosis plants which employ ion exchange membranes. Their natural advantages such as high selectivity, energy efficiency and ease of operation as compared to other membranes boosts their usage. The municipal sector has also ramped up spending on water treatment infrastructure to provide clean drinking water.
Ion exchange membrane market consists of companies that manufacture and sell membranes used in various separation processes involving ion exchange. Ion exchange membranes are used to selectively transport either positively or negatively charged ions across the membrane, while blocking the passage of ions with the opposite charge. Key applications of ion exchange membranes include electrodialysis, which uses them to desalinate water or concentrate brine, as well as fuel cells and batteries that utilize them in ion transport.
