EU Directive 2014/94/EU includes a mandate that outdoor HRSs must comply with the technical specifications in ISO/TS 20100 (which has now been replaced by ISO TC 19880-1). In order to implement the hydrogen quality control methods specified in this ISO standard and in ISO 19880-8, development and trialling of online purity analysers must be performed to ensure that they can continuously provide low level purity measurements without drifting and that hydrogen refuelling operators can easily install the instruments at HRSs. Without validating these quality control methods, the stations cannot have confidence in the performance and accuracy of the impurity analysers and it could also lead to the instruments providing incorrect measurements (allowing harmful levels of impurities to reach the hydrogen vehicle).
