How is the balance between cost and efficiency evolving in electrolyzers through material science?
Electrolyzers split water into hydrogen and oxygen using electricity. Their economics determine whether clean hydrogen can compete with fossil-based alternatives across industry, transport, and power storage. Historically, high capital cost and modest efficiency limited deployment. Over the past decade, *materials science* has become the main lever for change, reshaping catalysts, membranes, electrodes, and structural components. The result is a steady drop in system cost per kilowatt and a rise in efficiency and lifetime.The main cost drivers in electrolyzersThe cost of an electrolyzer is not driven by any single component, so progress emerges from a range of material enhancements rather than…
