Impact of Hydrogen Injection on Natural Gas Measurement

Hydrogen is increasingly receiving a primary role as an energy vector in ensuring the achievement of European decarbonization goals by 2050. In fact, could be produced also electrolysis water using renewable sources, such photovoltaic and wind power, being able to perform storage function, well through injection into natural gas infrastructures. However, hydrogen directly impacts thermodynamic properties itself, density, calorific value, Wobbe index, sound speed, etc. Consequently, this practice leads changes metrological behavior, especially terms volume quality measurements. paper, authors present overview on impact particular, mixtures with different H2 contents have been evaluated effects accuracy conversion at standard conditions investigated both theoretical point view experimentally. To end, discuss effect networks static ultrasonic domestic meters, from experimental view. Experimental tests demonstrated that meters are not significantly affected up about 10%.
