AB This work addresses the potential of hydrogen injection into the transmission high pressure natural gas grid as way to decarbonise the gas system and gas uses. To achieve this potential, knowledge gaps have to be covered considering the current know-how on how different concentrations of hydrogen gas could affect the infrastructure and its components. The activities are developed within the frame of HIGGS (FCH 2JU funded project, No. 875091). An R&D platform working at high pressure has been developed in HIGGS to achieve advance the knowledge on operation of hydrogen admixtures in the high-pressure natural gas grid, simulating the operational conditions from selected equipment, gas quality, etc. The admixture levels consider various hydrogen concentrations until reaching pure hydrogen. So far, the impact of H2/NG blends with up to 20 %vol H2 on steels and equipment has been studied through a mechanical and chemical characterization after been exposed to the blend. Membrane technology has also been tested for hydrogen recovery, using a Pd-based membrane prototype installed in the platform.

NO This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking under Grant Agreement No. 875091. This Joint Undertaking receives support from the European Union's Horizon 2020 Research and Innovation programme, Hydrogen Europe and Hydrogen Europe Research. HIGGS project, funded by the Fuel Cells and Hydrogen 2 Joint Undertaking (FCH 2JU) under Grant Agreement no. 875091, aims to pave the way to decarbonisation of the gas grid and its usage by hydrogen injection. The R&D platform developed in the project will help to perform experiments with materials and equipment present in the transmission gas grid to check their readiness for the transport of hydrogen in the near future. So far, blends with 20% vol hydrogen content has been tackled and the suitability of membrane technology to recover the hydrogen blended in end-uses has also been studied, showing promising results for understanding how prepared the natural gas grid is for the new tendencies of the market.
