G 404 (M)
Provisions for the Technical Reduction of Methane and Hydrogen Emissions in the Gas Infrastructure

Title (German)

Maßnahmen zur technischen Reduzierung von Methan- und Wasserstoffemissionen in der Gasinfrastruktur

Brief description

Many of the measures listed in this Code of Practice G 404 have already been used in the gas infrastructure for years for safety reasons, but if applied promptly they also lead to a de facto reduction in emissions and thus make an important contribution to reducing the burden on the environment. The main measures used in practice are listed in this leaflet. According to the current state of knowledge, these can also be used in networks for hydrogen-containing methane-rich gases (2nd gas family) and for hydrogen (5th gas family) in accordance with DVGW Code of Practice G 260.
