Researchers developing electrolyzers for hydrogen production are turning to anion exchange membranes (AEM) to scale up technology. AEM enables selective ion transport and aids in splitting water to produce hydrogen. Companies like Ecolectro and Re:Build are partnering to deploy advanced AEM electrolyzers in the US, while Michelin collaborates to develop durable membranes for renewable markets. Challenges in scaling green hydrogen include cost and efficiency compared to other methods like proton exchange membranes (PEM) or alkaline electrolysis. AEM offers a promising solution with better efficiency at lab scale. Companies like Enapter, Agastya, and Hygreen Energy are already using AEM electrolyzers at various scales. Ecolectro's AEM electrolyzer stack uses cost-effective materials. Challenges include adapting AEM for renewable energy sources and ensuring membrane durability. Michelin's Alcal'Hylab collaboration aims to deploy a durable membrane in an AEM electrolyzer stack by 2027. Despite skepticism, AEM technology advancements show potential in making green hydrogen a competitive renewable energy source in the future.
