Sensor for detecting hydrogen leaks
Honeywell presents a new sensor for hydrogen leak detection (HLD) that uses thermal conductivity detection technology to detect even the smallest leaks from 50 ppm in real time.
Honeywell's HLD sensor has been designed to operate without regular manual intervention. If the HLD sensor is installed near a hydrogen tank, gas line, fuel cell or in a vehicle interior, it does not need to be adjusted or manually calibrated for ten years. This minimizes maintenance, downtime and labour costs.
"Hydrogen has tremendous potential to power our global infrastructure - but safety must be a top priority," said Moin Shafai, Chief Technology Officer of Honeywell Sensing Solutions. "Through innovations in leak detection, Honeywell is helping to protect hydrogen-powered systems and the people who operate them in the face of growing global demand."
One user of Honeywell's HLD solution is BWR Innovations. The company's Oncore Energy System, a hydrogen fuel cell generator for residential and commercial use, is equipped with Honeywell's HLD sensors.
As hydrogen is increasingly used in critical infrastructure such as construction machinery, residential generators, heavy-duty trucks and buses, global demand is growing rapidly. According to a report by the Hydrogen Council, there were around 90,000 hydrogen fuel cell vehicles on the road worldwide in 2024 - an increase of 14% compared to 2023.
