The next decade is expected to witness significant growth in green energy technologies, with ion exchange membranes playing a crucial role in various applications. Ion exchange membranes, particularly used as solid electrolytes, are anticipated to see rising adoption in decarbonized energy and transport markets. In hydrogen fuel cells, ion exchange membranes are essential for the electrochemical reaction of hydrogen and oxygen to produce electricity, with perfluorinated membranes dominating the technology due to their high performance and durability. Fuel cell electric vehicles (FCEVs) are increasingly seen as viable options for long ranges and heavy-duty vehicles, especially in countries like Japan, Korea, and China. Water electrolyzers are expected to capitalize on the growing demand for green hydrogen production globally, driven by national hydrogen strategies and private sector investments. On the other hand, redox flow batteries are also embracing ion exchange membranes, particularly cation exchange membranes, with vanadium RFBs leading the demand. Overall, the outlook for ion exchange membranes in green energy technologies is positive, with material suppliers gearing up to meet the increasing demand.
