This presentation will focus on durable, high-performance materials and interfaces for advanced water splitting, enabling a clear pathway for achieving <$2/KgH2 (on the scale) with an efficiency of 43 KWh/Kg using an anion exchange membrane interface. Advances via a fundamental understanding of hydrogen and oxygen evolution reactions (HER/OER) leading to novel materials will be presented in conjunction with critical improvements in membrane and ionomers and gas evolution electrodes. Mechanistic details of the electrocatalysis, particularly hydrogen evolution reaction, will be given with corresponding characterization and testing. This presentation will show a comprehensive effort to enable such technology. Progress towards the end of the project goal of 1.76 Vcell(no-iR corrected) at 1A/cm2 will be highlighted wherein at the modeled scale of 50,000 kg/day and operating at 1 A/cm2 results in hydrogen cost at $2.15, $1.82, or $1.76/kg, respectively (2, 20, 200 plants). In addition, a road map for achieving $ 1/Kg in a decade will be delineated.
