About elementarhy

elementarhy is a Germany-based technology company focused on the development, production, and recycling of Membrane Electrode Assemblies (MEAs) used in Proton Exchange Membrane (PEM) electrolyzers. These components play a central role in the production of green hydrogen through water electrolysis. The company applies a proprietary plasma coating process that enables more efficient use of materials and aims to improve the overall sustainability and scalability of PEM electrolyzer systems.

A notable feature of elementarhy’s technology is the significant reduction in iridium usage—up to approximately 95%—compared to conventional MEA manufacturing methods. This reduction addresses concerns related to the cost and limited availability of critical raw materials. In addition, the MEAs are designed without the use of PFAS (per- and polyfluoroalkyl substances), aligning with emerging environmental standards and regulations.

elementarhy also incorporates circular design principles, offering a closed-loop system that supports both the initial production of MEAs and the recycling of used components. This approach contributes to material efficiency and reduced waste. The company's technology is intended to lower overall electrolyzer stack costs by an estimated 25–50%, supporting the economic viability of green hydrogen as an energy carrier.

With compatibility for existing PEM systems and emphasis on modular, scalable solutions, elementarhy addresses key technical and economic challenges in the green hydrogen value chain. Its offerings are relevant to sectors including energy, mobility, and industrial processes seeking low-emission alternatives.
