In the pursuit of clean and renewable energy, hydrogen plays an important role. But a major challenge facing this transition is that the gas is explosive when mixed with air. For this reason, it is crucial to be able to detect hydrogen leaks as early as possible. Now researchers at Chalmers University of Technology, Vrije Universiteit Amsterdam and Eindhoven University of Technology, have developed an optical sensor that can detect record low levels of hydrogen.
