Hydrogen detection using fiber optic sensors
Überschreitet die Wasserstoffkonzentration in der Luft einen Schwellenwert von vier Prozent, was bei ausreichend Druck in einem Wasserstofftank schnell erreicht werden kann, genügt ein einzelner Funken, um eine Explosion auszulösen.

Hydrogen plays a pivotal role in Germany’s energy and climate policy. In comparison to other gaseous or liquid energy sources, special security requirements have to be considered for applications with hydrogen, because additionally to fire hazard under certain conditions an explosive air hydrogen mixture can arise from leaks in tanks or piplelines. To further increase safety levels when dealing with hydrogen, researchers at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz Institute, HHI are working on fiber-optic-based sensors that can detect hydrogen and are superior to conventional sensors in many respects.
