How do advances in catalysts and membranes enhance electrolyzer performance and lifespan?
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 electrolyzersElectrolyzer cost is not dominated by a single part. Improvements therefore come from multiple material upgrades rather than one breakthrough.Catalysts: precious metals or…
