What role do material innovations play in reducing electrolyzer system costs per kilowatt?
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.Key factors shaping the overall cost of electrolyzersElectrolyzer cost is not dominated by a single part. Improvements therefore come from multiple material upgrades rather than one breakthrough.Catalysts: precious…
