This report documents the current state of development of five different electrolyzer technologies: proton exchange membranes, liquid alkaline, oxide-ion-conducting solid-oxide electrolyzer cells, alkaline exchange membranes, and proton-conducting solid-oxide electrolyzer cells. Boundary-level techno-economic analysis- using grid scenarios for electricity cost – shows that the current cost of hydrogen produced from these types of electrolyzers ranges from approximately $6/kg to $8/kg (depending […]
