Hydrogen regulation/standard in European countries for injecting hydrogen into natural gas grid

Hydrogen emerges as a key element in the journey towards decarbonizing energy systems. One strategy involves injecting limited amounts of hydrogen into existing natural gas networks through blending. Although this practice remains uncommon, a few demonstration projects are operational. However, injecting hydrogen alters the quality parameters of natural gas, a factor subject to varying approaches across European countries. These approaches include national regulations, standards, gas company requirements, and specific contracts with producers. MARCOGAZ has been gathering data on hydrogen injection requirements across European nations to monitor its adoption. This third update of their publication, following editions in 2016 and 2020, incorporates information from 12 European countries, revealing changes in quality parameter requirements in some jurisdictions.
