A new technical whitepaper has highlighted concerns over the reliability of hydrogen pressure sensors as discrepancies emerge between datasheet specifications and real-world performance.
The whitepaper authored by pressure sensor maker Druck and available on h2-view.com, warned that many sensors marketed “hydrogen-compatible” can suffer from issues such as drift, embrittlement, and permeation when exposed to harsh, high-pressure hydrogen environments.
Hydrogen sensors are used throughout the value chain – from electrolysers and fuelling stations to pipelines and storage – providing real-time monitoring to ensure safety, efficiency and compliance.
However, the paper argues that long-term drift specifications are often quoted under ideal conditions, which do not account for real-world factors such as temperature swings, hydrogen impurities, and pressure cycling.
