End user appliances and applications can currently handle 3% H2 except for some sensitive feedstock users and CNG filling stations. However, some applications are only able to accommodate hydrogen if the concentration is not fluctuating much.
This percentage is expected to go up to 20% in the mid-term depending on the sector and natural gas base composition. There are sectors that are not able to accommodate these higher hydrogen concentrations and they prefer to make the change to 100% H2 directly. In the long-term, most sectors have plans that allow for a retrofit to 100% H2.
These are the first conclusions of the work started in September last year by the Prime movers’ group on Gas Quality and Hydrogen handling which is co-chaired by Peter van Wesenbeeck ( EASEE-gas ) and Ruggero Bimbatti (GD4S).
The primary objective of the group is to facilitate the development of innovative and cost-effective ways to handle gas quality in fluctuating blends as well as pure hydrogen grids in our future gas systems. The information gathered during this project will be compiled in a final report.
The group also aims to provide inputs to the European Commission’s work on the “Hydrogen and decarbonised gas market package” expected to be published before the end of this year.
About 40 European organisations from across the whole gas value chain are part of this initiative.
