Review on the HIGGS Closing Conference in Brussels from 20th November to 21st November 2023

The HIGGS – Hydrogen in Gas Grids- Closing-Conference took place as part of the European Hydrogen Week in Brussels at the Brussels Expo.
For ERIG those have been very eventful days for.
On Monday, 20th November, we discussed our project results on the integration of hydrogen into the transport network alongside the HIGGS consortium and the Advisory Board.
On Tuesday, 21st November, the entire project was publicly presented to more than 50 participants as a side event of the EUH ydrogen Week.

It was a great project conclusion, and we would like to thank everyone who took part. The most important results and experiences made during the HIGGS project were summarized in a brochure that can be accessed through the following link:

The key take aways were:

  • Material and component testing under Hydrogen atmosphere:
    The European transport network is suitable for transporting hydrogen. Currently, the EU Gas Package is aiming for allowing a maximum of 5% hydrogen blending in cross-border transport. However, the technical conditions for higher concentrations are clearly established and noteworthy.
  • Techno-economic modelling of repurposing of European gas grid:
    Repurposing the gas grid is more cost-effective than constructing new infrastructure. This presents clear financial incentives.
  • Potentials, barriers and enablers of Hydrogen injection in Europe:
    There is still much to be done at the regulatory level. Simplification and standardization of regulatory requirements for operating dedicated hydrogen pipelines are necessary.
