elementarhy develops and manufactures advanced, scalable Membrane Electrode Assemblies (MEAs) for green hydrogen production via PEM electrolyzers, with a focus on efficiency, durability, and sustainability.
About
elementarhy is a Germany-based company specializing in the development, manufacturing, and recycling of Membrane Electrode Assemblies (MEAs) for proton exchange membrane (PEM) electrolyzers. Their innovative technology transforms volatile renewable energy into green hydrogen by water splitting. Originating from research and collaborations with the Leibniz Institute of Plasma Science and Technology, the University of Copenhagen, and the University of Bern, and validated by the German Aerospace Center, elementarhy provides cost-competitive and scalable MEA solutions to electrolyzer manufacturers. The company’s mission is to accelerate the transition to a zero-emission society by making green hydrogen production more efficient, cost-effective, and resource-friendly. Their technology significantly reduces critical raw material usage and is both PFAS-free and recyclable. elementarhy operates from Hamburg with a development center in Greifswald and has received significant backing from the German Ministry of Economics and Climate Protection and institutional partners across Europe.
