Techno-economic assessments of electrolyzers for hydrogen production

This review provides a comprehensive techno-economic assessment of four leading electrolyzer technologies such as the Alkaline Water Electrolyzers (AWE), Proton Exchange Membrane (PEM) electrolyzers, Solid Oxide Electrolyzer Cells (SOEC), and Anion Exchange Membrane (AEM) systems for green hydrogen production. Drawing on more than 40 peer-reviewed studies and real-world deployment scenarios, the analysis compares performance indicators such as levelised cost of hydrogen (LCOH), capital expenditure (CAPEX), operating expenditure (OPEX), efficiency, stack durability, and water treatment requirements. AWE is identified as the most cost-effective option for baseload power contexts, while PEM offers superior…
