Honeywell has launched a cutting-edge Hydrogen Leak Detector (HLD) that promises to significantly enhance safety standards across hydrogen-powered systems. Designed to detect even microscopic leaks in real-time, the new sensor uses advanced Thermal Conductivity Detection (TCD) technology to identify hydrogen levels as low as 50 parts per million (ppm).
As the hydrogen economy rapidly expands to support cleaner energy solutions across construction, transportation, and residential sectors, the safe handling of this volatile gas remains a top priority. Hydrogen is odourless, colourless, highly flammable, and capable of escaping through the smallest openings in storage or pipeline systems, making leak detection both critical and challenging.
“With hydrogen playing a key role in the global shift to clean energy, safety must lead innovation,” said Moin Shafai, Chief Technology Officer of Honeywell Sensing Solutions. “Our new leak detection technology gives operators the power to identify and address leaks before they become hazards, reinforcing confidence in hydrogen as a sustainable energy source.”
One of the early adopters of Honeywell’s HLD is BWR Innovations, which has integrated the sensor into its Oncore Energy System, a versatile hydrogen fuel cell generator used in residential and commercial applications.
“The integration of Honeywell’s HLD sensor provides reliable leak detection that enhances the operational safety of our hydrogen-powered systems,” said Adam Jorgenson, COO of BWR Innovations. “It allows us to continuously monitor equipment in real-time, which is essential for maintaining performance and safety.”
Honeywell’s HLD solution is designed with minimal maintenance requirements. Unlike conventional hydrogen detectors that require frequent calibration, the HLD sensor can operate for up to 10 years without manual adjustment. This dramatically reduces downtime and labor costs for operators in sectors like construction, power generation, shipping, and transportation.
The hydrogen economy is gaining momentum. A recent Hydrogen Council report highlighted that approximately 90,000 hydrogen fuel cell vehicles were in use worldwide in 2024, a 14% increase from the previous year. With hydrogen increasingly used to power everything from heavy-duty trucks to residential power systems, Honeywell’s new sensor is expected to play a vital role in ensuring the safe and efficient growth of this critical energy segment.
