| Project Name | High Capacity Electrolyzers Based on Ultrathin Proton-Conducting Oxide Membranes |
| Project Detail | Columbia University proposes a low-temperature water electrolyzer for hydrogen production based on ultrathin oxide membranes that can increase electrolysis efficiency by 20% compared with conventional polymer electrolyte membrane (PEM) electrolyzers. The enhanced performance of Columbia’s proton-conducting oxide membrane (POM) electrolyzers is enabled by the lower ionic resistance of dense oxide-based membranes that are 2 orders of magnitude thinner than conventional catalyst-coated membranes. If successful, the capital cost of POM electrolyzer stacks will be significantly lower than today’s PEM electrolyzers and more efficient to operate. These benefits will be key enablers toward $1/kg hydrogen costs. Potential Impact: Producing carbon-free green hydrogen from low-temperature (< 100 °C) water electrolysis is a highly attractive approach to enabling large-scale decarbonization across a variety of end-use sectors. |
