Delft sensor enables safe and reliable use of hydrogen – TU Delft

Scientists at TU Delft develop sensors that enable the safe and reliable use of hydrogen as a clean energy carrier, particularly in extreme environments such as aviation, polar operations, and liquid hydrogen storage. This innovation accelerates the adoption of hydrogen energy, contributing to the global transition to a carbon-neutral society.

TU Delft scientists team up

To tackle the need for hydrogen sensors for aviation applications, scientists from the Faculties of Aerospace Engineering and Applied Sciences teamed up. Supported by funding from EU projects Overleaf and HYDEA, an interdisciplinary team is now working on developing both the materials making detection of hydrogen possible, as well as the optical components and integration of the hydrogen sensors with other sensor technology. Focussing on hydrogen-powered aircraft, sensors to detect hydrogen leakages are required at various locations to ensure safe operations of the airplane. Think about near hydrogen storage tanks, propulsion systems, but also along hydrogen pipes. At these locations, temperatures can get down to as low as -60 °C during flight.

It remains fascinating that a layer thousand times thinner than a human hair changes its optical properties when a hydrogen leakage is present in such a way that it can even be detected by the naked eye.
