- Abstract:
- This work analyzes the readiness of low-carbon hydrogen to be blended to natural gas, or eventually a mixture of natural gas and biomethane, transmission pipelines network in Brazil with metrological traceability. An approach involving Quality Infrastructure, metrological reliability, and the description of both the main parts of natural gas networks and the hydrogen embrittlement phenomenon was used to obtain an overview of their joint effects in pipelines´ parts. On analyzing all aspects described before with the most relevant international standards applicable in pipelines, there was a lack of information on Metrology quantities flow rate, pressure, density, composition, calorific value and measuring stations, so it was possible to conclude what is necessary in Brazil in terms of existing pipelines that transport natural gas to blend with hydrogen.
