Nortegas injects into the network a blend of 15% green hydrogen and 85% natural gas in the third test phase of its H2SAREA project.

Nortegas has successfully completed the third test phase of its H2SAREA project, in which it has injected a blend of 15% hydrogen and 85% natural gas into a scale replica of its distribution networks.

The tests conducted by Nortegas enable it to estimate that blending green hydrogen with 15% natural gas would avoid 2.5 million tonnes of CO2 emissions per year, equivalent to the emissions generated by 2.7 million households, or 34% of the total natural gas consumption in Spain.

Nortegas added that the results obtained can be extrapolated to the national distribution network, as this infrastructure is modern and would also safely cater for the introduction into the grid of green hydrogen blended with natural gas. The company pointed out that this represents an opportunity to decarbonise final demand in a cost-efficient way, using existing natural gas distribution infrastructure with little investment required by the gas system.

Nortegas has highlighted that it is also working on the analysis of the compatibility of current gas distribution networks with renewable gases, and in particular with hydrogen, through the H2SAREA project.
