ZSW rolls out inspection system to assure the quality hydrogen and H2 filling stations.

Hydrogen refueling stations for fuel cell-powered cars have one thing in common with conventional petrol stations: They must be inspected and approved before they are put in operation, and regular checked for quality afterwards. The Centre for Solar Energy and Hydrogen Research in Baden-Württemberg (ZSW) has de-veloped a mobile certification system to ensure gaseous hydrogen refueling equipment is in compliance with international standards. This device measures pressure and temperature during refueling, checks the infrared communication between the vehicle and the filling station, and detects the amount of delivered hydrogen. Samples are taken at the same time, and then the hydrogen is analyzed for impurities. All this is aimed to drive the roll out of hydrogen infrastructure and thus the adoption of climate-friendly, alternative mobility solutions.

Further information on this new mobile measurement system for hydrogen fuel cell technology will be presented at the ZSW's booth H71 at the Hannover Messe on April 24 through 28.
