One of the final hurdles to hydrogen power is securing a safe method for spotting hydrogen leaks. A sensor, featured in the June issue of Sensor Technology, has a greater sensitivity than other detectors.

“Our spark-free optical-based hydrogen sensors detect the presence of hydrogen without electronics, making the process much safer,” said Tho Nguyen, associate professor at the University of Georgia.

The device features a nanosphere template covered with a Palladium Cobalt alloy layer. Any hydrogen present is quickly absorbed, then detected by an LED.  (Read the Tech Brief for more details.)

What do you think? Will Better Sensors Lead to Greater Adoption of Hydrogen Power?
