Fast hydrogen transport at the atomic level is a fundamental prerequisite for the operation of these technologies. We work on the discovery and design of new hydrogen ion (proton, H+, and hydride, H-) conducting materials with high conductivity at reduced temperatures. These materials will help enabling the widespread use of hydrogen as a zero-carbon fuel for energy generation, as well as for application
