To inject green hydrogen (H2) into the existing natural gas (NG) infrastructure is one way to decarbonize European energy system. However, asset readiness necessary be successful. Preliminary analysis and experimental results about compatibility of mixtures (H2NG) with actual grids make scientific community confident feasibility. Nevertheless, specific technical questions need more research. A significant topic debate impact H2NG on performance state-of-the-art fiscal measuring devices, which are essential for accurate billing. Identifying addressing any potential degradation in their metrological due critical decision-making. literature lacks data meters' technologies currently installed NG grids, such as a comprehensive overview at different concentrations while fragmented among sources. This paper addresses these gaps by analyzing main characteristics categorizing than 20,000 meters THOTH2 project partners' summarizing traditional pure H2 based review, operators experience manufacturers knowledge. Based insights, recommendations given stakeholders overcoming identified barriers facilitate smooth transition.
