National laboratory research

A water electrolysis technology that splits water into hydrogen and oxygen while shuttling hydroxide ions through an alkaline polymer membrane. AEMWE combines the cost benefits of traditional alkaline electrolysis with the compactness and efficiency of membrane-based technologies.

A nanoscale heterostructure composed of two complementary metal phosphides designed to replace platinum in water electrolyzers. One phosphide phase excels at breaking water apart, while the other facilitates hydrogen atom combination and release.

An oxygen evolution catalyst used in alkaline electrolyzer systems as a complement to the phosphide cathode. It is a proven, earth-abundant alternative to precious metal anodes.
