In air hydrogen has a wide flammability limit from 4 to 77% by volume and an explosive limit from 18 to 59%. The activation energy for ignition is extremely low and can be triggered by a very small spark or static discharge. Hydrogen is an odourless, colourless gas and can go undetected without specialised technology.
Early detection of hydrogen leaks is critical to maintaining safety across the hydrogen lifecycle — from production to storage, transport, usage in fuel cells and H2 ICE. With applications spanning transport, marine, aviation, and industrial sectors, Metis Engineering’s new sensor meets this critical need, creating new benchmarks for safety in hydrogen technologies.
"We’re excited to introduce this advanced sensor, addressing critical safety concerns in hydrogen storage and battery management systems," said Joe Holdsworth, CEO of Metis Engineering. "Our aim is to equip customers with forward-thinking solutions that elevate safety and enhance the resilience of their energy storage infrastructure."
