Twenty five different hydrogen samples have been taken from 16 different hydrogen plants or occasions and analysed for all contaminants listed in ISO 14687-2. Results of hydrogen fuel quality from the two main production processes (PEM water electrolysis with TSA and SMR with PSA) are presented for the first time in an open-access publication in The Journal of Power Sources. (IF 7.467). NPL piloted successfully the study.
