A2.1.4 Technical Report on the current status and future plans within the European gas distribution grid, models for hydrogen flow, and liquid hydrogen supply chains

The objective of this document is to provide input to stakeholders on the issues related to transport and measuring of hydrogen. An overview of the current status and future plans for measurement of hydrogen and transport within Europe is given; emphasis is put on the European gas distribution grid, the models for hydrogen flow, and the liquid hydrogen supply chains; also, the uncertainty of hydrogen flow meter calibrations for relevant supply chains, including relevant flow metering technologies, is discussed. A summary of these outputs can be found at the end of the document.
