Hydrogen Quality Sampling Apparatus (HQSA)

Hydrogen dispensers at fueling station for fuel cell vehicles must confirm that these dispensers meet fuel quality guidelines. The HQSA was designed, developed, and tested to support fuel station certifications. The portable and easy-to-use technology safely collects samples for analysis to measure hydrogen quality at the fuel station’s dispenser nozzle. Additionally, this apparatus was used to support the development of an ASTM standard for collection of pressurized hydrogen gas samples.
