Hydrogen: U.S. National Work Group

Hydrogen: USNWG

The USNWG works to promote, encourage, and participate in the establishment of a comprehensive set of legal metrology standards for commercial measurement of hydrogen for vehicle and other refueling applications including (1) device design, accuracy, installation, and use requirements; (2) method of sale requirements; (3) test procedures; and (4) fuel quality standards. The ultimate goal is that these standards will ensure the accuracy of measurements, enhance consumer protection, foster fair competition, and facilitate economic growth and trade.

The USNWG works through in-person meetings, conference calls, and email. The USNWG is currently accomplishing its goals through two subcommittees; one works to simultaneously refine equipment standards and test procedures and a second works on fuel specification requirements. For questions about meeting summaries and agendas please send a request to the USNWG Contact available through the Resources Helpful Hydrogen Links and Contacts listed below.
