The global ion exchange membrane (IEM) market, valued at over $12 billion, is critical for CO2 electrolyzers, water treatment, energy storage, and hydrogen production. However, current IEMs are expensive, inefficient, and reliant on PFAS-based materials, which are environmentally harmful and increasingly regulated. These limitations increase costs, hinder scalability, and slow industrial decarbonization, affecting industries that rely on membrane-based processes for carbon capture and clean energy production. Despite advancements in membrane science, existing technologies remain inadequate for scalable carbon capture, CO2 electrolysis, and hydrogen production, limiting their climate impact. For example, CO2 electrolyzers, which convert carbon dioxide into valuable liquid fuels and chemicals such as ethanol and formic acid, suffer from low efficiency and poor liquid product concentration due to membrane limitations, significantly reducing their economic viability. These inefficiencies stem from poor ion selectivity, high resistance, and high energy consumption, making large-scale deployment costly. Meanwhile, rising CO2 emissions accelerate ocean acidification, weakening the ocean’s ability to sequester carbon and worsening climate instability. Enhancing membrane efficiency is essential for improving CO2 conversion and ocean acidification mitigation, yet existing membranes fail to meet cost, energy, and performance demands, preventing widespread adoption.
