DVGW Information GAS Nr. 29 01/2023

Content of DVGW Information GAS No. 29

This DVGW Information GAS No. 29 provides an overview of the requirements that must be met for the use of hydrogen in systems for the pipeline-bound supply of the general public and the connected gas applications so that these can be labelled "H2-ready". 

In this DVGW Information GAS No. 29, a model is proposed to visualise the different levels of assessment in order to classify statements on the readiness of infrastructures for the grid-based supply of hydrogen. The term "H2-ready" is used to describe this readiness for hydrogen use, which is explained in the respective context in this DVGW Information GAS No. 29. 

The proposed model can also be applied analogously to new or existing plants for operational self-supply in which hydrogen is to be used, taking into account the specific legal requirements. 

Safe operation with the hazardous substance natural gas is already guaranteed for gas supply networks and gas applications. If a natural gas network is converted into a hydrogen network, the same level of safety can be guaranteed if the DVGW Codes of Practice applicable to hydrogen are taken into account - without prejudice to other legal requirements.
