Efficient hydrogen sensing with atomically engineered materials

ended

Hydrogen will be a key element of our future decarbonised economy as a sustainable energy vector. In the future economy, efficient hydrogen sensors will be a critical element. The high flammability of air-hydrogen mixtures and the minimal input power required to trigger combustion pose serious safety concerns. The light nature of the hydrogen molecule and its high diffusivity makes detection and leakage-control particularly challenging. Leak detection in a distribution network requires the availability of sensing elements with demanding performance targets. The objective of this project is to harness recent results in fundamental research in oxide electronics to develop an innovative material platform for ultra-sensitive resistive hydrogen sensors.
