WP 1 Flow metering

Flow metering – To develop metrology infrastructure to support new flow metering requirements, including development of new traceable facilities to enable calibration of flow meters for hydrogen and hydrogenenriched natural gas in the gas grid in accordance with the Directive 2014/32/EU Measuring Instruments (MID) with maximum permissible errors as low as ± 1 % depending on the type of flow meter, and metering of carbon dioxide in Carbon Capture and Storage (CCS) processes in accordance with the Emissions Trading System (EU ETS) with an accuracy of ± 1.5 – 2.5 %.

New measurement infrastructure will be developed in the related EMPIR JRP 18NRM06 NEWGASMET and new data will be collected characterising the performance of existing commercial domestic and distribution gas flow metering technologies with hydrogen. There is some field experience for metering of carbon dioxide in CCS applications, but there is a lack of independent flow measurement facilities and primary standards. This project will develop traceable flow calibration facilities and primary standards for pure hydrogen and hydrogenenriched natural gas which will extend the range of flow rates and mixtures that can be tested. A meter testing programme will target existing commercial gas flow meters, but also newly developed domestic gas flow meters designed for use with hydrogen. New primary flow standards will be developed for metering carbon dioxide and representative CCS mixtures, and several flow meter types will be tested. The test programme will include CCS mixtures with carbon dioxide in both gas and liquid states.
