Description succincte (Anglais)

As one of the measures to reduce greenhouse gas emissions, the use of hydrogen should increase. To achieve this goal, the metrological infrastructure for hydrogen needs to cover all supply lines. This project provides novel and improved standards for the safe application of hydrogen, flow measurement, hydrogen quality assessment and custody transfer. Together with outcomes from previous projects, an infrastructure is established that provides measurement data that are fit for demonstrating compliance with regulations andcontracts. They ramping up the use of hydrogen and society to adapt itself to using hydrogen to replace fossil fuels.

Objectifs du projet (Anglais)

1. To develop calibration and measurement methods to support reliable, traceable, and accurate measurements of hydrogen in production processes and end-user applications, in view of safety, process efficiency and environmental issues, such as for purity, leak detection, odorisation, and
   materials performance, ensuring that online measurement instruments and sensors are operating within their specifications (ISO 14687, OIML R139, and OIML R140) (WP1).
2. To develop measurement standards to enable calibration and validation of flow metering equipmentunder actual conditions (pressure, temperature), used to accurately quantify flow rates of hydrogen (including blended hydrogen) through the hydrogen supply chain, and to ensure compliance with
   respect to, e.g., OIML R137, OIML R139, OIML R140, and the Measurement Instruments Directive (WP2).
3. To develop and improve measurement standards and methods to enable traceable validation and performance evaluation of gas quality measurement methods, to thus improve on the current lack of equivalence for e.g. oxygen, hydrogen sulphide, moisture content, and for reactive components such
   as hydrogen chloride and chlorine. To develop and improve analysers for critical impurities for online monitoring changes in gas quality, through the supply chain and processing equipment, to ensure the gas quality is meeting the required specifications (ISO 14687) (WP3).
