Researchers develop a versatile hydrogen sensor

Hydrogen is playing an increasingly important role in the transition to a completely sustainable economy.

However, under certain circumstances, hydrogen is a combustible and sometimes even an explosive gas, so it is important to track down the tiniest hydrogen leaks as quickly as possible. This makes cheap, reliable sensors that can quickly detect small amounts of hydrogen of vital importance. Researchers at TU Delft have now developed a material that is extremely suited to this task.

At present hydrogen is usually detected with relatively large and expensive equipment, which often needs both oxygen and electricity to function properly.
